Product Description

Light weight: The body is made of high-grade ductile black cast iron, which is about *0% to *0% lighter than traditional gate valves and is easy to install and maintain. Flat-bottom 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 not easy to fall off and Good elastic memory. Precision cast valve body: The valve body is precision cast. The precise geometric dimensions ensure the sealing of the valve without any finishing work inside the valve body.

Advantages of national standard gate valve

1. The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium. 2. Opening and closing requires less effort. 3. The flow direction of the medium is not restricted, and it does not disturb the flow or reduce the pressure. 4. Simple shape, short structural length, good manufacturing process, and wide application range.
