Manual metal sealing gate valve
Product details
Features
Light weight: The body is made of high-grade ductile black cast iron, which is about 20% to 30% lighter than traditional gate valves and is easy to install and maintain. Flat-bottomed gate seat: Traditional gate valves often have foreign objects such as stones, wood blocks, cement, iron filings, debris, etc. accumulated in the groove at the bottom of the valve after the pipe is washed with water, which can easily lead to leakage due to inability to close tightly.
The bottom of the elastic seat seal gate valve adopts the same flat bottom design as the water pipe machine, which is not easy to cause debris accumulation and allows the fluid to flow smoothly.
Overall rubber coating: The gate uses high-quality rubber for the overall inner and outer coating. Europe's first-class rubber vulcanization technology enables the vulcanized gate to ensure precise geometric dimensions, and the rubber and ductile cast gate are firmly connected and are not easy to fall off and Good elastic memory. water Precision cast valve body: The valve body is precision cast, and the precise geometric dimensions ensure the sealing of the valve without any finishing work inside the valve body.
Product advantages
The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium. Opening and closing requires less effort. The flow direction of the medium is not restricted, and there is no flow disturbance or pressure reduction. It has a simple shape, short structural length, good manufacturing process, and wide application range.
Precautions
The handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
Double-gate gate valves should be installed vertically (that is, the valve stem is in a vertical position and the handwheel is at the top).
Before opening the gate valve with a bypass valve, the bypass valve should be opened first (to balance the pressure difference between the inlet and outlet and reduce the opening force).
Gate valves with transmission mechanisms should be installed according to the product instruction manual.
If the valve is frequently used on and off, lubricate it at least once a month.
