Description
Pressure Reducing Valve with Solenoid IR-420-55-BK (for tape)
The Bermad Model IR-420-55-bK is a hydraulically operated, diaphragm actuated control valve.
This valve accurately reduces higher upstream pressure to very low and stable preset downstream pressure, regardless of fluctuating demand or varying upstream pressure. It either opens or shuts in response to an electric signal. The valve is designed specifically to regulate irrigation low pressure tape products
Applications:
- Computerized Irrigation Systems
- Drip-Tape Systems
- Low Set Pressure Applications
- Remote and/or Elevated Plots
- Distribution Centers
- Low Supplied Pressure Irrigation Systems
Line Pressure driven, Solenoid Controlled PRV
- Protects downstream systems
Pressure Reducing Servo Pilot Controlled
- Dynamic integrated needle valve
- Settable to 0.5 bar; 7 psi
- Very low hysteresis
Advanced Globe Hydro-Efficient Design
Unobstructed flow path
- Single moving part
- High flow capacity
Fully Supported & Balanced Diaphragm
- Requires low actuation pressure
- Excellent low-flow regulation performance
- Progressively restrains valve closing
- Prevents diaphragm distortion
User-Friendly Design
Simple in-line inspection and service
Operations
The Shuttle Valve hydraulically connects the Solenoid or the Pressure Reducing Servo Pilot (PRSP) to the Valve Control Chamber. When the solenoid is closed, the PRSP commands the Valve to throttle closed, preventing Downstream Pressure from rising above pilot setting.
In response to an electric signal, the solenoid switches, directing line pressure thought the shuttle valve into the control chamber. This causes the Valve to shut. The solenoid also features local manual closing.
