Product Description

Welding vacuum isolation stop valve The valve is suitable for working temperature ≤425ºC and ≤550ºC, the working medium is water, steam or air pipeline, as a opening and closing device; Especially suitable for steam condensing and vacuum negative pressure system in thermal power plant, it plays the role of vacuum isolation and sealing.
1, the main body of this series of valves adopts casting and
forging structure, with parallel double sealing pair semi-forced bidirectional seal, sealing surface in place movement and wedge wedge movement step by step to achieve zero leakage.
2, the sealing surface movement friction is small, light opening and closing, and the sealing surface wear has automatic compensation function.
3, simple structure, compact, easy maintenance, long service life.
4, this series of valve connection forms are divided into flanges, welding two, driving methods are manual, electric two.
