Flanged Forged Steel Gate Valve

Description
Flanged 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 flanged gate valve (flanged sluice 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 gate valve is valve disc. The movement direction of disc is perpendicular to the flowing direction of fluid. Gate valve can only be opened or closed fully.

Applications
Flanged 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.

Features
1. Sealing material can be selected according to fluid so as to increase sealing property and wear resistance of the flanged gate valve and decrease cost.
2. Flanged sluice valves can be classified according to fluid’s pressure grades (such as 900LB, 1500LB and 2500LB).
3. Flanged forged steel gate valve needs small torsion to open.
4. Valve body adopts precision casting technique.
5. Twice shot blasting processing on outer surface makes the flanged steel valve look fine and smooth.
6. Numerical control processing is utilized on valve disc.
7. Valve seat is replaceable, which makes maintenance more simple and convenient.
