Product Description
The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm-actuated control valve that accurately reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand or varying upstream pressure.
Features and Benefits
- Line Pressure Driven, Hydraulically Controlled
- Protects downstream systems
- Pressure Reducing Servo Pilot Controlled
- Dynamic integrated needle valve
- Easily settable to 0.5 bar; 7 psi
- Very low hysteresis
- Plastic Globe Hydro-Efficient Valve
- Unobstructed flow pat
- Single moving part
- High flow capacity
- Highly durable, chemical and cavitation resistant
- Unitized Flexible Diaphragm and Guided Plug
- Excellent low-flow regulation performance
- Prevents diaphragm erosion and distortion
- Fully Supported & Balanced Diaphragm
- Requires low actuation pressure
- User-Friendly Design
- Simple in-line inspection and service
1. BERMAD Model IR-220-bZ establishes a reduced pressure zone, protecting laterals and the distribution line.
2. BERMAD Solenoid Controlled Valve Model IR-110-N1
3. BERMAD Vacuum Breaker Model ½”-ARV
Typical Applications
- Drip-Tape Systems
- Low Set Pressure Applications
- Low Supplied Pressure Irrigation Systems
- Energy Saving Irrigation Systems
Technical Data
Operation
The Pressure Reducing Servo Pilot [1] commands the Valve to throttle closed, preventing Downstream Pressure [P2] from rising above the pilot setting, and to modulate open when [P2] drops below the pilot setting. The Manual Selector [2] enables local manual closing.
