Description
Features

1.With pressure balancing function and high sensitivity

2.Low noise, reliable performance, and maintenance free

3.Adopting standard modular design

4.Multiple combination controls can be achieved through assembly component

 

Self-operated pressure control valve consist of a control valve, an actuator, and a spring for setting pressure.Suitable for non-corrosive liquids, gases, and steam, and can be used for pressure control either upstream (when the upstream pressure increases, the control valve opens) or downstream (when the downstream pressure increases, the control valve closes) in the system pipeline. It is widely used in the petroleum, chemical, power, metallurgy, medicine, food, textile, machinery, and HVAC industries.
