Overview
The BERMAD Top Pilot Pressure Reducing Control Valve with 2-way solenoid control (model IR-22T-55-2W) provides compact, high-performance pressure reduction for irrigation systems. It reduces higher upstream pressure to a calibrated constant downstream pressure regardless of flow fluctuations and opens when line pressure drops below the setting. The valve is line-pressure driven and hydraulically controlled; it opens and closes in response to an electric signal when solenoid control is used.

Key Features & Benefits

• Line pressure driven, hydraulically controlled On/Off
  • Protects downstream systems
• 2-way integrated pilot — user-friendly design
  • Adjustment knob with high-resolution scale enables easy calibration without a pressure gauge
  • Compact box-size solution
  • Internal self-cleaning control — no external tubes
  • Solenoid control can be added or removed easily
• Smooth valve opening and closing
  • Accurate and stable regulation
  • Low operating pressure requirements
• Composite hydro-efficient globe valve
  • Unobstructed flow path
  • Single moving part
  • High flow capacity
  • Durable, chemical- and cavitation-resistant materials
• Unitized flexible diaphragm and guided plug
  • Excellent low-flow regulation performance
  • Prevents diaphragm erosion and distortion
• Fully supported & balanced diaphragm
  • Requires low actuation pressure

Typical Applications

• Automated irrigation systems
• Systems subject to varying supply pressure
