Product Description
The BERMAD Model 123-X is a hydraulically operated, diaphragm-actuated control valve that sustains minimum preset upstream (back) pressure and reduces downstream pressure to a constant preset maximum.
Features and Benefits
- Line Pressure Driven, Hydraulically Controlled
- Protects downstream system
- Prioritizes pressure zones
- Controls system fill-up
- Engineered Plastic Valve with Industrial Grade Design
- Highly durable, chemical and cavitation resistant
- No internal bolts and nuts
- hYflow ‘Y’ Valve Body with "Look Through" Design
- Ultra-high flow capacity –Low-pressure loss
- Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug
- Accurate and stable regulation with the smooth closing
- Requires low opening and actuation pressure
- Prevents diaphragm erosion and distortion
- User-Friendly Design
- Easy pressure setting
- Simple in-line inspection and service

Operation
![Bermad - 123 - Operation](https://deeco-production.s3.amazonaws.com/images/Bermad_-_123_-_Operation.width-1000.png)
The Pressure Reducing Pilot (PRP) [1] is hydraulically connected to the Valve Control Chamber [2] through the Pressure Sustaining Pilot (PSP) [3]. The PSP commands the Valve to throttle closed should Upstream Pressure [P1] drops below the setting. When [P1] rises above the setting, the PSP switches and allows the PRP to control the Valve, commanding it to reduce Downstream Pressure [P2]. The Manual Selector [4] enables local manual closing
