Pressure Relief Valve Application

Tips: How does a pressure relief valve work?

The pressure relief valve adjusts the flow of the medium by controlling the opening of the opening and closing parts in the valve body and reduces the pressure of the medium. Inside, spray cooling water into the valve body or behind the valve to reduce the temperature of the medium. This valve is called a pressure reducing and temperature reducing valve. The characteristic of this valve is to keep the outlet pressure and temperature within a certain range under the condition of constant change of inlet pressure.
