Product Description

The flange gate valve is a gate valve with a flange connection. This type of connection is the most common. Flange gate valves are stable and reliable when used in pipelines, so flange gate valves are often used in high pressure pipelines.

Light weight: The body is made of high-grade ball black cast iron (nodular cast iron), which is about 20%~30% lighter than traditional gate valves, and is easy to install and maintain.
Flat-bottomed gate: Traditional gate valves are often deposited in the groove of the valve bottom due to foreign objects such as stones, wood blocks, cement, iron filings, debris, etc. after the water is washed, which is easy to close and form a water leakage phenomenon. The bottom of the elastic seat sealing gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation, so that the fluid is unobstructed.
Integral encapsulation: The ram is made of good quality rubber for the whole inner and outer rubber. The rubber vulcanization technology in Europe enables the vulcanized ram to ensure precise geometrical dimensions, and the rubber and spheroidal cast slabs are firmly secured, not easy to fall off and elastic. it is good.
Precision cast valve body: The valve body is precision cast, and the geometric size allows the valve body to be sealed without any machining.
1. The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium.
2, opening and closing is more labor-saving.
3. The flow direction of the medium is not restricted, no disturbance, no pressure reduction.
4. Simple shape, short structure length, good manufacturing process and wide application range.
