Bermad

IR-22T Top Pilot

Pressure reducing
Pressure
Rated 150 psi; operating range 10–150 psi; adjusting scale and spring 12–40 psi (2-way only) or 12–80 psi
Sizes
3/4", 1", 1½", 2" (DN20–DN50) — globe or angle
Best for
The 200 Series Top Pilot — same integrated pilot and adjustment dial as the IR-12T in the compact 1½"–2" body most greenhouse and nursery zones use. Bermad restricts the warranty to irrigation use only

IR-220-55 (solenoid controlled)

Pressure reducing
Pressure
Rated 150 psi; operating range 10–150 psi; pilot springs 3–25 psi (green), 7–43 psi (grey), 12–95 psi (natural), 15–150 psi (blue/white)
Connection
Threaded globe or angle; 3-way control loop. AC solenoid S-390-T-2W, or S-982 for DC latching
Sizes
1½" & 2" — globe or angle, threaded; Cv 43–47 on 1½", 54–60 on 2"
Best for
Regulates and switches from one body — it holds a constant downstream pressure regardless of demand, and opens or shuts on an electric signal from the controller. That is the combination an automated block wants: no separate zone valve upstream of the regulator. Composite hydro-efficient globe body, single moving part, unobstructed flow path. Excellent low-flow regulation and smooth opening and closing, so it will not slam the line. Four pilot springs cover 3 to 150 psi

IR-220

Pressure reducing
Pressure
Rated 150 psi; operating range 10–150 psi; pilot spring 3–25 psi (green)
Sizes
1½" & 2"
Best for
The 200 Series answer for small agricultural blocks — same pressure-reducing function as the IR-120 in a compact 1½"–2" body. Available with solenoid control for combined regulation and on/off

IR-12T Top Pilot

Pressure reducing
Pressure
Rated 150 psi; operating range 7–150 psi; adjusting scale and spring 12–40 psi (2-way only) or 12–80 psi
Connection
Threaded or PVC; 2-way or 3-way control loop
Sizes
1½", 2", 2½", 3" (PVC on 3" and 3"L)
Best for
Bermad’s newer 100 Series design — the pilot is built into the valve top with a high-resolution adjustment dial, so you set the downstream pressure by turning a numbered scale instead of swapping springs. Compact, plug and play, and quick to calibrate accurately in the field. Reduces higher upstream pressure to a constant downstream pressure regardless of flow, and opens fully when line pressure drops below setting

IR-120 hYflow

Pressure reducing
Pressure
Rated 150 psi; operating range 7–150 psi; pilot spring 3–25 psi (green) and higher ranges
Connection
Threaded, flanged or Victaulic PVC adaptors (3", 4")
Sizes
1½", 2", 2½", 3", 4" (6" on some builds)
Best for
Reduces higher upstream pressure to a lower constant downstream pressure regardless of fluctuating demand, and opens fully if line pressure drops. hYflow "Y" body with a look-through design gives very high flow capacity at low pressure loss. Engineered composite body — no internal bolts or nuts, chemical and cavitation resistant. Unitized Flexible Super Travel (FST) diaphragm regulates accurately and closes smoothly. Available with solenoid control (-55) so one valve both regulates and switches on/off

IR-420

Pressure reducing
Connection
Threaded or flanged; cast iron body
Sizes
1"–16" (DN25–DN400)
Best for
The metal 400 Series — over 30 years in the market and the best value in the Bermad line. Full-bore seat with an unobstructed flow path; one-piece elastomeric diaphragm vulcanized to a radial seal disc, peripherally supported so it will not distort. Reduces higher upstream pressure to a lower constant downstream pressure. Suits computerized irrigation systems, distribution centers and filter stations

IR-920 Hydrometer

Pressure reducing
Pressure
Rated 250 psi; operating range 7–250 psi; pilot spring 12–95 psi (natural) or 15–150 psi (blue/white)
Connection
Ductile iron body, reinforced nylon and brass internals
Sizes
1½", 2", 3", 4"
Best for
A hydrometer and a pressure reducing valve in one unit — meters the water and regulates downstream pressure from the same body, so a zone needs one fitting instead of two. Highest pressure rating in the Bermad irrigation line at 250 psi
Catalog ↗

IR-820 Hydrometer (solenoid controlled)

Pressure reducing
Pressure
Rated 150 psi; operating range 7–150 psi; pilot spring 12–95 psi
Connection
Threaded or flanged; solenoid control
Sizes
1½", 2", 3", 4"
Best for
All-in-one mainline flow meter and pressure reducing valve, with solenoid control added — it meters the water, regulates downstream pressure and switches the zone from one body. Saves fitting a meter, a regulator and a zone valve in series

Netafim

Series 80 Nylon (Pressure Reducing)

Pressure reducing
Pressure
7–150 psi; spring ranges 7–30 psi (yellow), 14–65 psi (green), 30–90 psi (red); max water 140°F
Connection
Nylon threaded; all pilots and solenoids assemble on the bonnet — no tubes run to the valve body
Sizes
1½" & 2" — globe or angle
Best for
Pressure regulation for small blocks, greenhouse and nursery including hydroponic and mist systems. Three colour-coded spring ranges cover 7 to 90 psi. Clog-free labyrinth inlet for the command water makes it usable on dirty water. Quick to react and seals drip-tight. Order codes PRTH, or PRELTH for the pressure reducing electric version

Series 75 Nylon (Pressure Reducing)

Pressure reducing
Pressure
5–145 psi (low-pressure diaphragm), 10–145 psi (high-pressure diaphragm); max water 140°F
Connection
Threaded; reinforced nylon body and bonnet, natural rubber diaphragm, SST 302 spring
Sizes
3/4", 1", 1½", 2", 3" threaded — Cv 26 to 110; max flow 9–75 gpm
Best for
Field crops, vineyards, orchards and greenhouses. One moving part — the diaphragm — and it sits out of the water passage, so there is very little to foul or service. Flexible diaphragm over a hydrodynamic body gives high flow at low head loss. Highly resistant to fertilizers and chemicals; polypropylene body and ALD or EPDM diaphragm available for aggressive chemistry

Series 90 PVC (Pressure Reducing)

Pressure reducing
Pressure
Max 145 psi; minimum operating 4 psi; minimum recommended flow 5 gpm
Connection
uPVC body; slip or threaded, for PVC networks
Sizes
3", 4", 6" — threaded or slip
Best for
Purpose-built for PVC mainlines — solvent-weld it straight into the run. Available with the full selection of control functions and an optional underground configuration

Series 100 Iron (Pressure Reducing)

Pressure reducing
Pressure
Max water temperature 176°F — the highest in the Netafim valve range
Connection
Cast iron (ASTM A126 CLB); threaded, flanged or grooved
Sizes
1", 1½", 2", 3", 4", 6", 8", 10", 12" — threaded, flanged, grooved or angle
Best for
Straight flow pattern with the lowest friction loss in the industry, per Netafim. The size range runs well past the plastics — up to 12" — so this is the mainline and pump-shed valve. Also offered manual and electric

Rivulis

V2000 (Pressure Reducing)

Pressure reducing
Pressure
To 145 psi (10 bar)
Sizes
1.5"–8" straight; BSP/NPT or flange
Best for
Reduces pressure downstream of the valve to keep every block uniform. Available as a straight pressure reducing valve or as pressure reducing electric, so one valve both regulates and switches
Catalog ↗

V2500 (Pressure Reducing)

Pressure reducing
Pressure
To 145 psi (10 bar)
Sizes
2"–6" — angle and straight
Best for
Piston-operated plastic pressure reducing valve for finer control of the regulation curve

V3000 (Pressure Reducing)

Pressure reducing
Pressure
To 145 psi (10 bar); over 6" rated to 232 psi (16 bar)
Sizes

Superior

950PRS Brass Valve with Pressure Regulation

Pressure reducing
Flow
5–320 gpm
Pressure
Inlet 20–200 psi; integrated module holds outlet constant between 10 and 125 psi. To 180°F
Sizes
3/4" to 3" — 950PRS075, 950PRS100, 950PRS125, 950PRS150, 950PRS200, 950PRS250, 950PRS300
Best for
The 950 with pressure regulation built into the valve rather than bolted on, so zone pressure is held whatever the mainline does. Regulation is maintained during manual operation, which a separate downstream regulator cannot promise, and it is fitted with a Schrader valve so the setting can be read with a normal pressure gauge. Red brass, internal bleed
