Solenoid Valves & Pressure Control

AC 24 V and DC latching globe valves from 3/4″ to 3″ (1-68 m³/h) plus the PR20 regulator – nylon-glass bodies, EPDM diaphragms, manual bleed standard.

RWV AC / DC Valves

3/4″ to 3″, 0.5-8.8 bar, manual override, slow-close.

PR20 Regulator

1.0-6.9 bar adjustable downstream pressure, ±0.2 bar accuracy.

AC or DC latching? AC 24 V valves pair with powered controllers in valve boxes near a transformer. DC latching (pulse 9-15 V) valves run on battery timers and solar controllers – no mains power needed. Both share the same hydraulic body.

Size	Model (AC / DC)	Flow	Working pressure	Coil
3/4″	RWV-75A / RWV-75D	0.98-8.66 m³/h	0.5-8.8 bar	AC24V ±10% / DC12V ±10% (9-15V), <100 ms pulse
1″	RWV-100A / RWV-100D	1.14-9.08 m³/h	0.5-8.8 bar	same
1¼”	RWV-120A / RWV-120D	6.18-20.30 m³/h	0.5-8.8 bar	same
1½”	RWV-150A / RWV-150D	6.81-22.70 m³/h	0.5-8.8 bar	same
2″	RWV-200A / RWV-200D	9.08-34.05 m³/h	0.5-8.8 bar	same
3″	RWV-300A / RWV-300D	34-68 m³/h	0.5-8.8 bar	same

Valve features

Manual flow control

Turn the flow stem to balance each zone; close it fully for service.

Manual bleed

Twist the solenoid a quarter turn to open the valve without the controller.

Anti water-hammer

Slow-close diaphragm design protects laterals and fittings.

Reversible diaphragm

Reverse-flow tolerant design keeps the valve sealed even with pressure loss.

Engineering polymer body

Nylon filled with glass fiber; brass inserts at thread bosses.

Media temperature ≤60 °C

EPDM diaphragm rated for landscape and treated water.

How do I size a solenoid valve?

Match the valve flow range to your zone demand at design pressure: 3/4″ covers up to 8.66 m³/h, 1″ up to 9.08 m³/h, 2″ up to 34.05 m³/h and 3″ up to 68 m³/h. Keep the valve in the middle of its range for stable regulation.

Can one valve run on both AC and DC controllers?

No – order the A version for AC 24 V controllers or the D version for DC latching battery and solar controllers. The coil differs; the body is identical.

Why does my valve not close?

Typical causes: debris under the diaphragm, a reversed flow without anti-siphon fit, or a trapped solenoid. RWV valves disassemble from the top for cleaning without cutting pipe.
