The valve has a simple structure, making manufacturing and maintenance easy; it has a short working stroke and fast opening/closing time. The sealing surface between the closing element (disc) and the valve seat adopts a conical seal, which requires low closing force, offers erosion resistance, and ensures good sealing performance. The valve seat is replaceable and can be arbitrarily combined with the sealing surface materials of the closing element to meet the requirements of working conditions and extend service life.
