Introduction
Forged steel butt weld end 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 forged steel gate 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. Butt weld end 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.

Maintenance of Butt Weld End Gate Valve
1. Hand wheel, handle and transmission mechanism are not allowed for lifting things. Collision of them is strictly prohibited.
2. Please open the bypass valve in advance before opening the valve to balance the pressure differential and to decrease opening force.
3. If the valve opens and closes frequently, please lubricate it regularly (at least one time every month).
4. The valve for long-term storage should be checked regularly. The surface of the valve must be clear of dirt and coated with anti-rust oil.
