Universal stop valve (valve installed at the end of the suction pipeline) intended for industrial installations. It can be used for water, chemicals, petrochemical products, etc., considering the chemical resistance of the valve material. The valve must be installed according to the flow direction indicated on the body, in a vertical position. Maximum constant working pressure across the full temperature range. Minimum opening pressure is directly proportional to the height of the water column above the valve, e.g., for 10 m, the opening pressure is 1.0 bar, for 5 m, the opening pressure is 0.5 bar. Body material: brass. Disc: brass. Disc sealing: NBR. Connection: BSP female thread. Operating temperature: from -10°C to +90°C.
