Wedge gate valve

Short Description:

Wedge gate valve because of its valve sealing surface and vertical center line into a certain angle, good sealing, so it can withstand large pressure. In general, the valve stem of wedge gate valve has good corrosion resistance and scratch resistance after quenching and tempering and surface nitriding treatment; the seal between gate and valve seat is made of cemented carbide, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant and has long service life; the valve body has complete materials, and the packing and gasket are based on the actual working conditions or user requirements.
