Product Details
This series of pressure reducing valve is a direct acting membrane spring pressure relief valve. Mainly by the adjustment of the spring, diaphragm, piston, valve seat, valve and other parts of the composition. Using the diaphragm direct sensing downstream pressure driven valve, control valve opening to complete the function of pressure relief. The product is in the hot and cold water supply system of urban buildings and high-rise buildings, which can replace conventional water pipes and save equipment. Can also be in the usual hot and cold water pipe network, the role of pressure relief. The product is adjustable and stable, and is suitable for the pipeline of water and non corrosive 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.
