Product Description
1. Self-Operated Upstream Pressure Control Valve consists of control valve, actuator and a spring for pressure setting.
2. Relies on medium pressure to drive top actuator and plug for regulation, no control system, external air or power source required.
3. Pipeline medium pressure signal is fed back to actuator, automatically adjusting plug opening to stabilize pressure.
4. Pressure set point can be adjusted at any time within allowable range during operation.
5. When upstream pressure exceeds set value, plug opens automatically to relieve pressure and stabilize upstream pressure.
6. Suitable for pressure stabilization control of liquids, gases and steam media, with condenser available for use up to 350℃.
Features & Benefits
1. Medium self driven, no external energy source required.
2. Automatically monitors upstream pressure, relieves pressure on overpressure.
3. Plug adopts pressure balanced structure, high sensitivity.
4. Low noise, reliable performance, maintenance free, continuous stable regulation.
5. Adopts standard modular design.
6. By matching different actuator and pressure spring combinations, different upstream pressures can be controlled.
7. Used for overpressure protection of storage tanks and pipelines.
