Description Material Performance Product Size Specifications

This series of pressure reducing valve is a direct acting bellows spring relief valve. Mainly consists of bellows, spring, valve seat, valve and other parts of the composition, the use of bellows sensing valve pressure valve, change and control valve opening to achieve the function of pressure relief. By adjusting the adjusting bolt to set the outlet pressure. The valve product pressure regulating and pressure stabilizing action is sensitive and balanced, and is suitable for the use of the pipeline of the gas and the liquid medium.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
