The gate valve is an opening and closing gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

Gate valve features

• light weight

The body is made of high-grade ductile iron, which is about 20%~30% lighter than the traditional gate valve, and is easy to install and maintain.

• Flat bottom brake seat

The traditional gate valve often accumulates in the groove of the bottom of the valve due to foreign objects such as stones, wood blocks, cement, iron filings, sundries, etc. after the pipe is washed with water, which is easy to cause the phenomenon of water leakage that cannot be closed tightly, and the elastic seat seals the bottom of the gate valve. It adopts the same flat bottom design as the water pipe machine, which is not easy to cause debris to accumulate, so that the fluid can be unobstructed.

• Precision casting valve body

The valve body is made of precision casting, and the precise geometric dimensions make it possible to ensure the tightness of the valve without any finishing inside the valve body.

Applications

This valve widely applied in the liquid pipes for opening or closing fixing in such water, sewage disposal, electric power, energetics pipe , chemical, shipping, energy sources etc.
