Product Details

Product Overview
The self operated front pressure regulating valve is composed of components such as the valve body and balance spring, without the need for external energy. It uses the pressure of the regulated medium as the power source to introduce the actuator to control the position of the valve core, change the pressure difference and flow rate at both ends, and make the front pressure stable. It has sensitive operation, good sealing performance, and small pressure set point fluctuations. Widely used for automatic control of pressure reduction and stabilization of gas, liquid, and steam media.

Performance characteristics
1. The pressure setting value of the self operated front pressure regulating valve can also be adjusted during operation;
2. Adopting fast opening flow characteristics, with sensitive action, high adjustment, and good sealing performance;
3. Automatic control of medium pressure such as gas, liquid, and steam in various industrial equipment;
4. Customized high-pressure or high-temperature types can be selected based on the pressure and temperature used on site.
