High Quality Industrial threaded globe valve China factory supplier Manufacturer
What's the Threaded globe valve ?
Threaded globe valve is a special design of small sizes globe valves.
As a globe valve,it has all the characteristics of globe valve,quick open and close.
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. The wedge gate valve can only be fully opened and fully closed and can not be adjusted and throttled.The gate valve was designed to be used either fully open or fully closed
but the Threaded globe 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 Threaded globe valve
Main features of the API602 forged steel globe 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.
- 5)Backseat designed to relieve back pressure on the stem packing when fully seated. Replacing stem packing under pressure is not recommended.
- 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.
