Ductile Iron DN150 Handwheel Flange Gate Valve 200 PSI Light Weight

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.

Technical Parameters:

Gate valve characteristics:
1. Light weight
2. Flat bottom brake seat

3. Overall encapsulation
4. Precision casting valve body
 

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.
5. If the valve is frequently opened and closed, lubricate at least once a month.
6. The gate valve is only used for the operation of all kinds of pipelines or media in the fully open and fully closed equipment, and is not allowed for throttling.
7. For gate valves with hand wheels or handles, no auxiliary levers should be added during operation (if the sealing is not tight, the sealing surface or other parts should be checked and repaired). Turn the handwheel and handle clockwise to close, otherwise open. The gate valve with transmission mechanism should be used in accordance with the product manual.
