China Forged Steel 800lb High Pressure Gate Valve China factory
What's the 800lbs gate valve ?
800lbs gate valve API602 Forged Steel Gate Valve is a special design of small sizes gate valves.
it has all the characteristics of gate valves.as normal,the opening and closing parts are the gate,in shape of a wedge,that's the reason that they are named as wedge gate valve.the direction of motion of the gate is perpendicular to the fluid direction.
but the800lbs gate valve has its own features.it's made in forged carbon steel,stainless steel,alloy steel,with compact body,suitable for high pressure fluid.the bonnet could be bolted,welded and pressure sealed,according to the working conditions.
Main features of the 800lbs gate valve
Main features of the API602 forged steel gate valve
- 1)Rising stem with precision acme double thread for quick operation.
- 2)Body to bonnet joint designed to apply a uniform load to the gasket to assure a leak proof seal.
- 3)Solid wedge.
- 6)Stem packing is designed for optimum control of fugitive emissions leakage to the atmoshphere. The ultra-low emission leakage rate is assured by the fine finish on the stem sealing area, the reduced diametrical clearences and the stem straightness control.
- 7)Bellows seal is available on request
- 8)Stellite seat rings provide increased resistance to wear, abrasion and erosion of the sealing surfaces.
- 9)expanded Seat Rings.
- 10)Low fugitive emissions control.
