Pressure Reducing Valve IR-420-54-3W-KX
The BERMAD Normally Closed, Pressure Reducing Valve with Hydraulic Control, is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand, and opens fully upon line pressure drop. It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.
- Hydraulic Pressure Control, Normally Closed
-Line pressure driven
-Closes upon control failure
-Protects downstream systems
-Opens fully upon line pressure drop
-Amplifies and relays weak remote command
- 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
-Easy pressure setting
-Simple in-line inspection and service
