Axial Flow Check Valves Series S.OK, Type S.OKOF for Energy and Petrochemical Applications

Backflow valves with axial movement of the gate, are used in pipeline systems of heat and power engineering and petrochemical industry to prevent the movement of the working medium in the opposite direction. They guarantee high tightness and low pressure losses, as well as ease of installation and operation. Diameter |mm|: from 80 to 500; Design pressure |MPa|: from 0.6 to 25; Medium temperature |C|: from 20 to 560; Medium |liquid, vapour, gas|: liquid, vapour, gas.
