Diaphragm valve IR-22T-55-3W-X

Product overview
BERMAD Top Pilot pressure reducing control valve IR-22T-55-3W-X with optional solenoid control reduces higher upstream pressure to a calibrated constant downstream pressure for irrigation systems. The integrated 3-way pilot includes a high-resolution adjustment dial for quick, accurate calibration. When line pressure falls below the setpoint the valve opens fully; when equipped with the solenoid the valve opens and shuts in response to an electric signal. This valve is intended for irrigation use only; manufacturer warranty is limited to permitted use.

Line pressure driven, hydraulically controlled On/Off

• Protects downstream irrigation equipment and networks
• Opens fully upon line pressure drop

3-way integrated pilot – user-friendly design

• High-resolution adjustment dial and scale for calibration without a pressure gauge
• Compact, box-size integrated solution
• Solenoid control is plug & play (easily added or removed)
• Suitable across sizes up to 3"

Smooth valve opening and closing

• Accurate, stable pressure regulation
• Low operating pressure requirements

Composite hydro-efficient globe valve

• Unobstructed flow path for high flow capacity
• Single moving part for simplified internals
• Durable, chemical- and cavitation-resistant construction

Unitized flexible diaphragm and guided plug

• Excellent regulation at low flow rates
• Prevents diaphragm erosion and distortion

Fully supported & balanced diaphragm

• Requires low actuation pressure

Typical applications

• Automated irrigation systems
• Systems subject to varying supply pressure
• Plot/zone valves in drip and sprinkler irrigation
• Energy-saving irrigation installations

Additional features

• Plastic test point
• ½" anti-vacuum at valve downstream
