Gate valve introduction:
Surface of the valve was covered with advanced epoxy and flashboard was covered with rubber. Other parts which will contact with medium are all made of stainless steel or copper alloy, which fundamentally prevent it from being contaminated by medium. It fits pipelines of drinkable water, food industry, fire water and sewage treatment.
Valve seat was particularly designed and surface of rubber covered flashboard has reliable performance. The valve has small torque of opening and closing and easy to operate or maintain. For there is no groove under pipeline of the valve that lowers the flow resistance in it and eliminates the damage of impurity depositing in valve, improving the service life of the valve.

Gate valve characteristics:
The body is made of high-grade nodular cast iron, the weight is about 20%~30% lighter than the traditional gate valve, and the installation and maintenance are convenient.
Flat bottom brake seat
After the traditional gate valve flushes the pipeline with water, foreign matter such as stone, wood, cement, iron filings, sundries and other foreign objects often silt up in the bottom groove of the valve, which can easily cause water leakage.
The bottom of the gate valve is sealed by an elastic valve seat. It adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris accumulation and makes the fluid flow unimpeded.
The gate adopts high-quality rubber for overall inner and outer rubber. European rubber vulcanization technology enables the vulcanized gate to ensure accurate geometric dimensions, and the rubber and ductile cast gate are firmly connected, not easy to fall off and have good elastic memory.
Precision casting valve body
The valve body is made of precision casting, and the precise geometric dimensions make the inside of the valve body without any finishing to ensure the sealing of the valve.
Note for gate valve:
1. Handwheels, handles and transmission mechanisms are not allowed to be used for lifting, and collisions are strictly prohibited.
2. The double gate valve should be installed vertically (that is, the valve stem is in the vertical position and the handwheel is on the top).
3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force).
4. The gate valve with transmission mechanism should be installed according to the product manual.
