The water-sealed gate valve is suitable for opening and closing the pipelines with nominal pressure of 100 MPa and working temperature of 425 C. The working medium is water, steam, oil and non-corrosive gas. It is especially suitable for vacuum condensing system of steam turbine in thermal power plant.


Product features of water seal gate valves


1, S/Z series adopt double gate two-way elastic seal, open and close flexible, fast and reliable sealing.


2, the product structure is simple, compact and reasonable, convenient maintenance, long service life.
