Pressure Reducing Valve IR-420-54-bK
The BERMAD Model IR-420-54-bK is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand or varying upstream pressure. It is a Normally Closed valve, which opens in response to a remote pressure drop command and shuts in the absence of that command.
- Line Pressure Driven Normally Closed PRV
-Protects downstream systems
-Closes upon control failure
-Amplifies and relays weak remote command
- 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
- Simple In-Line Inspection and Service.
Typical Applications
- Computerized Irrigation System
- Drip-Tape Systems
- Low Set Pressure Applications
- Remote and/or Elevated Plots
- Distribution Centers
