Socket Welded Forged Steel Gate Valve
Introduction
Socket weld forged steel gate valve is a kind of most common open/close valve. It is mainly composed of valve body, disc, bonnet, valve gland, gasket, bolt and nut. This socket weld valve uses disc to connect or cut off medium in pipeline. Disc functions like a sluice gate to connect or cut off media, so it is called gate valve or sluice valve. The on-off component of valve is valve disc. The movement direction of disc is perpendicular to the flowing direction of fluid. Sluice valve can only be opened or closed fully. Flanged sluice valves can be classified according to fluid’s pressure grades (such as 900LB, 1500LB and 2500LB).
Applications
Socket weld forged steel gate valve can be widely applied as fluid regulating and intercepting equipment in various pipelines, such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, and energy pipeline systems.
Advantages
1. Numerical control processing is utilized on valve disc.
2. Valve body adopts precision casting technique.
3. Sealing material can be selected according to fluid so as to increase sealing property and wear resistance of the socket weld valve and decrease cost.
4. Valve seat is replaceable, which makes maintenance more simple and convenient.
5. Socket weld forged steel gate valve needs small torsion to open.
6. Twice shot blasting processing on outer surface makes the forged steel valve look fine and smooth.
7. Lifelong technology service is provided for all our products.
