Irrigation Valve Attributes

Irrigation valves are the remote control valves that open and close a zone: 3/4 in to 3 in diaphragm bodies in globe, angle and anti-siphon patterns, in glass-filled nylon for landscape work and in brass, bronze or cast iron for golf, sports turf and high-pressure mainlines. Pool, spa and irrigation distributors sell them three ways at once — to contractors buying a box at the counter, to techs replacing a failed body in a valve box, and to designers writing a submittal against CSI 32 84 23.

The data is hard for a structural reason: almost everything a buyer filters on lives in a part-number suffix rather than a field. Size is encoded in the model prefix (100PESB is the 1 in), the scrubber is a letter, the pressure-regulating module is a separate line item, and the reclaimed build is a purple handle kit ordered on its own. The numbers that decide the sale — pressure loss at flow, inrush and holding current, regulation range — are printed in tech-spec PDFs and never reach the record.

Then three manufacturers spell the same thing four ways, and the catalog inherits all four.

Core

Every SKU needs these. Without them the record is not a product, it is a row.

Nominal Valve Size
enum · in (DN)
1 in (DN 25)

First filter on every rail. Contractors buy to match the lateral — a 1 in valve on 1 in pipe. Drives flow range, pressure loss and price band.

Body Pattern
enum
Globe/Angle (convertible body)

Globe takes inline flow; angle takes the inlet from below and cuts pressure loss on a riser; anti-siphon adds the vacuum breaker. Not swappable on a job.

Inlet x Outlet Connection
enum
1 in FNPT x 1 in FNPT

FNPT, slip, male-by-barb, union and BSP bodies are separate SKUs. Wrong end and the contractor is cutting the manifold apart at the truck.

Actuation Type & Fail State
enum
Electric solenoid, normally closed

Normally closed zone valve vs. normally open master valve vs. manual. A normally open body on a zone leaves the zone running when the controller is off.

Solenoid Rating
enum · VAC / VDC
24 VAC, 50/60 Hz

24 VAC is the standard; 9 VDC latching is required for battery controllers. A latching valve on a 24 VAC controller never opens, and the tech blames the valve.

Operating Pressure Range
range · psi
20-200 psi (1.38-13.8 bar)

Below the minimum the diaphragm won't seat and the valve weeps; above the maximum the body is out of spec. Filtered on every commercial job.

Flow Range
range · gpm
0.25-200 gpm (1.2-757 L/min)

The manufacturer's recommended envelope. Under-flow a valve and it chatters; over-flow it and it burns the pressure the heads needed.

Body Material
enum
Glass-filled UV-resistant nylon

Glass-filled nylon covers most landscape work. Brass, bronze and cast iron go where pressure rating, vandalism or a golf spec demands it.

Diaphragm Material
enum
Nylon-reinforced nitrile (Buna-N)

Nitrile is the default; EPDM and chlorine-resistant compounds are what survive effluent. The diaphragm is the first thing that fails in the field.

Manufacturer Part Number (MPN)
identifier
100PESB

The only string contractors actually type. It also encodes size and options, which is exactly why the options still need their own fields.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

Flow Control Stem
boolean
Yes (external flow control handle)

Lets the tech throttle a zone at the valve. Rain Bird advises turning the stem down two full turns below 10 gpm. Sold as a distinct model, not a note.

Pressure Regulation
enum
PRS-D module, 15-100 psi (+/-3 psi), ordered separately

Regulating module holds outlet pressure regardless of inlet. Buyers need the range and whether it ships in the box or is a separate line item.

Debris Handling
enum
Self-cleaning scrubber, stainless steel screen

Dirty, effluent or well water decides the sale. A scrubber scrapes its stainless screen every cycle; a plain body needs a Y-filter upstream instead.

Pressure Loss at Design Flow
number · psi
5.6 psi at 30 gpm (100-PEB, flow control fully open)

What the designer actually hydraulically calculates with. Flow range says the valve will pass it; loss says what it costs you at the head.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

Backflow Prevention Listing
enum
ASSE 1001 atmospheric vacuum breaker; IAPMO and CSA listed

Anti-siphon bodies integrate an atmospheric vacuum breaker and must carry the listing the AHJ will look for. Blank on globe/angle bodies.

Reclaimed-Water (Non-Potable) Configuration
enum
Purple handle + chlorine-resistant diaphragm (NP)

Reclaimed sites require purple identification and a chlorine-resistant diaphragm. Inspectors check the handle, not the invoice.

GTIN / UPC
identifier
00610116347119

Gate for marketplace listing and for any customer scanning at the counter or on a truck. No GTIN, no Amazon Business listing.

Country of Origin
identifier
Mexico

Required for customs and USMCA claims, and asked for on public-agency and federally funded landscape work.

The fields that aren't in the schema at all

What most irrigation valves catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Supplier signal
+ Solenoid Inrush / Holding Current

Every manufacturer tech spec publishes it — 0.41 A (9.84 VA) inrush, 0.14 A (3.43 VA) holding at 60 Hz, 30-39 ohm coil. Distributor records carry 'Voltage: 24V' and stop there.

Two-wire and decoder designers can't count valves per decoder or size the wire run, so the BOM gets built on the manufacturer's site instead of yours.

Marketplace signal
+ Pressure Regulation: module included, and its range

Product Q&A on the same SKU keeps asking whether the regulator ships in the box. The module is a separate line item; the only trace of it is a 'PRS' fragment inside the title string.

Valve arrives without the regulator. Return, restock, a second trip to the branch, and the zone runs at line pressure until the module shows up.

Search signal
+ Reclaimed-Water (Non-Potable) Configuration

Site search for 'purple handle', 'non-potable' or 'reclaimed valve' returns nothing, because the configuration exists only inside a part-number suffix like -NP-HAN1.

Reclaimed jobs get built with standard handles and standard diaphragms. The inspector flags the identification and the valves come back out.

Competitor signal
+ Bonnet Access Type (jar-top vs. bolted)

'Jar Top' is the reason contractors buy it and it shows up in competitor product titles and copy — but no filter rail exposes it as a facet you can select.

A service buyer who wants tool-free bonnet access can't filter for it, scans two pages of results, and calls the counter that can answer.

Supplier signal
+ Installed Dimensions (H x L x W)

Tech specs give height, length and width per size and note that the pressure-regulating module adds about 2 in of height. Catalogs carry carton dims and ship weight instead.

Retrofit buyers can't tell whether valve plus module clears an existing valve box lid. Guess wrong and the box gets dug up and replaced.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way pool, spa & irrigation suppliers spell it. A filter only works once they agree.

Nominal Valve Size
1"1 in1.0 IN25mmDN25100 (26/34)
1 in (DN 25)

Model prefixes encode size (100 = 1 in); metric price files use the 26/34 BSP designation. All four land in the same catalog.

Solenoid Rating
24V24 VAC24VAC 60Hz24 volt AC9V DC latching6-9 VDC
24 VAC, 50/60 Hz

'24V' alone doesn't say AC or DC. A DC-latching valve on a 24 VAC controller won't open, and the return comes back as 'defective'.

Inlet x Outlet Connection
FNPTFIPTF.I.P.T.1" FPTFemale NPTBSP
1 in FNPT

FPT, FIPT and FNPT are one thread. BSP is a different form that won't seal against NPT and must never merge into the same bucket.

Body Pattern
GlobeGLOBE/ANGLEGlobe or AngleInlineIn-line globeAngle Pattern
Globe/Angle (convertible body)

Most plastic RCVs are one body that installs either way. Splitting a convertible body into two values invents SKUs and splits inventory.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

  • Will a 1 in valve pass 30 gpm without eating more pressure than I have?
  • Is this the globe or the angle version, or does the same body do both?
  • Does the pressure regulator come with the valve, or do I order the module separately?
  • Can I run this off a 9 V battery controller, or does it need 24 VAC?
  • What's the inrush and holding current — how many can I hang on one decoder?
  • This zone is reclaimed. Does it come with the purple handle and chlorine-resistant diaphragm?
  • The water here is full of grit. Do I need the scrubber model or a Y-filter upstream?
  • Can I get the bonnet off in the valve box without tools?

Irrigation Valves data, in practice

Do irrigation valves need NSF/ANSI 61 or lead-free certification?

Usually not — and stamping the claim on a record that doesn't carry it is a real exposure. Section 1417 of the Safe Drinking Water Act, as amended by the Reduction of Lead in Drinking Water Act, covers products conveying water for human consumption. Products used exclusively for irrigation and outdoor watering fall outside that scope, which is why most zone valves downstream of the backflow preventer carry no NSF/ANSI 61 or 372 listing and their manufacturers claim none. What does belong on the record is the backflow listing on anti-siphon bodies: those integrate an atmospheric vacuum breaker and carry ASSE 1001, IAPMO and CSA listings.

Should globe and angle be one SKU or two?

Follow the body, not the marketing. Most plastic remote control valves in the 3/4 in to 2 in range are a single convertible body that installs either inline (globe) or with the inlet from below (angle) — one part number, one bin. Model that as Body Pattern = 'Globe/Angle'. Dedicated angle bodies and anti-siphon bodies are genuinely different parts and get their own value. Distributors that split a convertible body into two records to fill a globe filter and an angle filter end up with phantom SKUs, split inventory, and two price rows that drift apart. The filter rail should let a buyer select 'Angle' and see both the dedicated angle bodies and the convertibles.

If I already publish flow range, why carry pressure loss too?

They answer different questions. Flow range is the manufacturer's recommended operating envelope — it tells you the valve will pass 30 gpm without chattering. Pressure loss tells you what passing 30 gpm costs: a 1 in PEB drops about 5.6 psi at 30 gpm with the flow control fully open, rising to roughly 10 psi at 40 gpm, while the 1-1/2 in body drops about 3.5 psi at that same 40 gpm. That number goes straight into the designer's hydraulic calculation and often decides whether they upsize the valve. Flow range wins the filter; pressure loss wins the specification.

How should the option suffixes be modelled?

As attributes, not as part-number soup. A single family can ship as globe or angle, with or without a scrubber, with or without a pressure-regulating module, with a purple non-potable handle kit, and with either a 24 VAC or a latching solenoid — before you get to NPT versus BSP threads. Encoding that combinatorial spread into title strings is what produces catalogs where nothing is filterable and the same option reads three ways across three brands. Give each option its own governed field, keep the MPN as the identifier it is, and record explicitly whether an option ships in the box or is a separate line item. That last flag prevents most of the returns in this category.
