All-welded ball valves Marshall
Control all-welded ball valves Marshall with flange connection 15-200/150 were put into production. Operating pressure of the valves is 1.6, 2.5 and 4 MPa.
Unlike standard ball valves the new ones possess the reduced thickness of casing wall made of steel 20 and the lock body (ball) made of 12X18N10T. It made it possible to reduce the weight of the valve and its cost. The valves are designed for use as a locking device on the pipelines that transport, water, gas, petroleum products and other non-toxic environment temperatuoy from -40 to +180°C.
