Product Description
The BERMAD Top Pilot Pressure Reducing Control valves offer top performance, compact design, and intuitive plug-and-play operation, thanks to an innovative integrated pilot, equipped with a high-resolution adjustment dial for easy, quick & accurate calibration. Model IR-12T-55-3W-X reduces higher upstream pressure to a calibrated constant downstream pressure, regardless of flow fluctuations, and opens fully when line pressure drops below setting. The valve opens & shuts in response to an electric signal.
Features and Benefits
- Line Pressure Driven, Hydraulically Controlled (on/Off)
- Protects downstream systems
- Opens fully when line pressure drop
- 3-Way Integrated pilot - user-friendly design
- Adjustment knob and high-resolution scale for easy calibration without a pressure gauge
- Compact “Box-Size” solution
- Solenoid control is easily added or removed
- Uniquely suitable to all size range up to 3”
- Engineered Plastic Valve with Industrial Grade Design
- Adaptable on-site to a wide range of end connection sizes and types
- Highly durable, chemical & cavitation resistant
- hYflow ‘Y’ Valve Body with “Look Through” Design
- Ultra-high flow capacity at Low-pressure loss
- Unitized Flexible Super Travel Diaphragm with a Guided Plug
- Accurate and stable regulation with smooth closing
- Requires low actuation pressure
- Prevents diaphragm erosion and distortion

Operation
![12T- Operation](https://deeco-production.s3.amazonaws.com/images/12T-_Operation.width-750.png)
The Pressure Reducing Pilot 1 commands the Valve to throttle closed should Downstream Pressure P2 rise above and to open fully when it drops below setting. The Integrated Trio Selector 2 enables manual closing and opening override or electric control, in which the solenoid 3 connects valve control chamber 4 with line pressure to shut the valve or vents it through the pilot to open the valve.
