Rising Stem Gate Valve: body material: cast iron or ductile iron stem:stainless steel applicable media:water gas andetc. pressure:1.0/1.6/2.5MPa The structure of rising stem gate valve is outlay lead screws structure,the leadscrew do the axial movement while rotating the valve flap move up and down to realize the switch function and it can be observed directly the opening of the valve.It is widely used in fire control indusrtial pipe and running water network system. Gate valves normally have flanged ends which are drilled according to pipeline compatible flange dimensional standards. Gate valves are typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels. Applications:The valve is widely used in the water supply,sewage treatment,neutralliquid in the mining industry, enterprise and the high building.
