Steam Glove Valves

Steam Glove Valves

Steam Valves are all characterized by a closer member, usually in disc or plug form, which is moved by the actuator perpendicular to a ring shaped seat. The flow passes from the inlet port through the seat to outlet port. The types differ mainly in the orientation of the seat to the direction of flow through the valve. There are many variations in seat, stem and bonnet design in Steam Valve. All the working parts are generally of stainless steel to avoid wear and tear.

Steam Valves are used primarily for steam purpose. They are used where pressure condition are severe and hence are heavier than most of the other type of valves. Steam valve can control flow and provide tight seal when fully closed. Steam valves are faster to open or close. Due to stainless steel working parts, there seating surface are less subject to wear and their high pressure drop makes them useful in controlling pressure. Due to heavy structure, such valves are costlier than other valves. In large size they require considerable power to operate, thus necessitating gearing, levers etc.
