Product Description
The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm-actuated control valve that reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop.
Features & Benefits
- Line Pressure Driven, Hydraulically Controlled
- Protects downstream systems
- Opens fully upon line pressure drop
- Smooth valve opening and closing
- Accurate and stable regulation
- Low operating pressure requirements
- Plastic Globe Hydro-Efficient Valve
- Unobstructed flow path
- 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-220-3W-XZ establishes a reduced pressure zone, protecting laterals and the distribution line.
2. BERMAD Kinetic Air Valve Model IR-K10
3. BERMAD Combination Air Valve Model IR-C10
Typical Applications
- Drip Systems

Technical Data
Operation
The Pressure Reducing Pilot 1 commands the main Valve to throttle closed should Downstream Pressure P2 rise above the pilot setting, and to open fully when it drops below the pilot setting. The Manual Selector 2 enables local manual closing.
