socket weld check valve Description
Socket weld check valve is a check valve connected to the pipeline by socket welding, belonging to the compact check valve, through the valve flap (such as spring-assisted flap or rotary flap) to automatically control the one-way flow of the medium to prevent backflow.
Characteristics
Structural characteristics
Compact design: socket welded port reduces the space for flange or threaded connection, suitable for pipeline dense area.
High sealing: welded connection without leakage risk, valve and valve seat with cobalt-based alloy or elastic sealing material, adapt to high pressure (such as PN320) and high temperature (550 ℃) working conditions.
Impact resistance: spring-assisted closure design can buffer the impact of water hammer and reduce valve vibration.
Performance Advantages
Low pressure loss: Y-type flow path optimises the fluid path and reduces flow resistance (refer to similar Y-type check valve design).
Fast Response: Spring preload adjusts flap opening and closing speed, suitable for frequent pressure fluctuation scenarios.
