Specification of this Forged Steel Gate Valve Gate Valve Forged Steel Gate Valve
Forged steel Gate valves are mainly used for the pipelines on various systems of thermal power station, especially for non-corrosive mediums like water and steam. Forged steel valves are characterized by close texture, better physical performance, so means high temperatures, high pressures. Usually it also has unique sealing design. The forged steel gate valves are available in three bonnet designs. The first design is the Bolted Bonnet, with male-female joint, spiral wound gasket, made in F304/graphite. Ring joint gasket are also available on request. The second design is the welded bonnet with a threaded and seal welded joint. On request a full penetration strength welded joint is available. The third design is the pressure seal bonnet, with a threaded and pressure seal bonnet joint.

Product advantage of this Forged Steel Gate Valve Gate Valve Forged Steel Gate Valve

Forged steel gate valve offers the following advantages:
1 forged steel gate valve fluid resistance is small, medium distressed by the sealing surface brush and water erosion.
(2) forged steel gate valve for Class150 ~ 2500, operating temperature -29 ~ 425 ℃ (carbon steel) or -29 ~ 500 ℃ (stainless steel) of small diameter pipeline, the pipeline used to cut off or connected to the media.

3 simple welded forged steel valve body, a short length of the structure, manufacturing process, good for a wide range.

4 gate is placed perpendicular to the valve body, and the level of cut-off valve flap is placed in the valve body, valve and thus shorter than the length of the structure.

5 forged steel gate valve of the internal media channel is through the medium flowing through the valve does not change its flow direction, so the fluid resistance.

6 forged steel gate valve movement direction perpendicular to the direction of the fluid can be fully open and fully closed.

7 use of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.

8 socket weld forged steel gate valve medium flows unrestricted, non-spoiler, not reduce the pressure.

9 very good sealing performance by the erosion of full-time small sealing surface.

10 stainless steel forged steel gate valve opening and closing more effort.

11 is relatively simple shape, the casting process is better for a wide range.
