Product description

Due to the unique characteristics of valves for long-distance pipelines, their ability to bear pipeline stress, safety, weather resistance and long-term reliability are fully considered in the design; The whole part and parts of the valve are forgings. Forged steel ball valves are mainly used in various high-pressure medium transmission pipelines in chemical, metallurgical, petroleum, pharmaceutical and other industries. The main design features of forged steel ball valves are: full diameter / reduced diameter; 90 degree positioning and locking structure; Special form of "Y" head handle; Fire protection and anti-static design; A pair of opposite butterfly springs; Anti blow out valve rod; Double sealing structure in the middle of valve stem; Seal the bonnet with bolts, threaded gaskets.

Applicable temperature: - 196 ~ 450 ℃

Driving mode: manual, pneumatic, electric and hydraulic;
