Socket weld Gate valve refers to a Gate valve with socket weld ends.
Simple welding is performed by inserting the pipe into the gate valve connection part for welding.
The connection form of welding is mainly used for small diameter valves and piping, fittings, and pipe welding. Small diameter pipeline is generally thin in wall thickness, edge dislocation and erosion, difficult to weld, is more suitable for socket weld. In addition, the socket weld port of plug and plug welding has a reinforcing effect, so it is also mostly used under high pressure.

Both NRS socket end flanged gate valves and flanged end gate valve's material can be CI/DI/WCB/SS
Both NRS socket end flanged gate valves and flanged end gate valve's pressure can be Class125/150, PN10/16,5K/10K/16K
Stardard:BS, DIN, ANSI, AWWA, SABS
Face to face:BS, DIN, ANSI, AWWA, SABS
Connection flange type:Socket end
NRS Socket End Flanged Gate Valves do not require bolting, they are sealed directly with the pipe end socket filled with rubber and can accommodate a range displacement and vibration of the pipeline.
If you leave the gate valves partially open or partially closed, there are a view disadvantages to this as listed below:
(1)A ripple effect being sent through the water, causing a noise or vibration.
(2)Restriction of flow.
(3)More chance of catching dirt.
(4)More wear to the gate valve than usual.
