Quick Detail

DIN/GOST flange gate valve is one of the most common on-off valves, which use the upper and lower working of the gate to connect (open) and cut off (fully close) the fluid medium in the pipeline. Such gate valves are widely used as regulating and shut-off devices in pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, marine, metallurgy, and energy systems.


Characteristics

1. The fluid resistance is small, and the sealing surface is less washed and eroded by the medium (the shutter opening height is high).

2. The opening is more powerful, the sealing performance is good, the flow direction of the medium is not restricted, the flow is not disturbed, and the pressure is not lowered.

3. Simple shape, good manufacturing process and wide application range.
