Product details
Overview of ZSPC Oxygen Quick Cut off Valve
The ZSPC oxygen quick cut-off valve consists of a pneumatic piston type actuator and a low flow resistance, dual sealing structure cut-off mechanism. The actuator has fast action speed, high thrust, spring reset function, and a manually operated mechanism; The valve body flow path is unobstructed, the flow coefficient is large, and the valve core and seat have elastic and rigid cascade dual seals. The novel and unique structure makes this product a high-performance new type of shut-off valve with fast action, tight shut-off, safety and reliability.
The sealing surface material of the cut-off valve core can be divided into hard seal and soft seal; According to the structure of the valve core, it can be divided into single guide flat plate type and single guide balanced type. It has the characteristics of simple structure, reliable action, tight cutting, and fast switching. Suitable for gas and liquid media without particles or impurities, requiring quick and tight closure, quick venting, and emergency shutdown. This product has excellent performance, complete specifications, small size, and light weight, and is widely used in automation control systems for industrial production processes such as chemical, petroleum, metallurgical, and textile industries.
