Introduction to Gate Valve
1. Scope of application
Gate valves are widely used as regulating and intercepting devices on the pipelines of tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, and energy systems.
2. Specifications and models
Pressure range: PN1.0—4.0
Nominal diameter: DN15—500
3. Connection method
(1)Internal thread
(2)External thread
(3)Flange type
(4)Welded
4. Performance characteristics
(1)Simple shape and short structure length.
(2)Small flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.
(3)Less effort when opening and closing. It is compared with the stop valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the direction of medium flow.
(4)Compact structure, good valve rigidity, smooth passage, small flow resistance, stainless steel and hard alloy sealing surface, long service life, PTFE packing, reliable sealing, light and flexible operation.
(5)The structural length (the distance between the two connecting end faces of the shell) is small.
(6)The medium can flow in any direction on both sides, easy to install.
