Overview
A swing check valve allows forward flow to move a hinged closure away from the flow path. When forward flow stops or reverses, the closure swings back onto its seat to limit reverse flow through the connected pressure-control assembly.
- Automatic nonreturn operation without an external actuator
- Hinged swing closure moves with the forward flow path
- Seats automatically when flow stops or reverses
- Flow direction must be verified during installation
- Final pressure class, materials, and connections confirmed per configuration
