This 25mm (1") Spears PVC swing check valve provides automatic non-return operation in solvent-welded water pipework. Forward flow opens the internal check and reverse flow closes it. The socket ends join matching PVC pipe. Correct flow direction, body orientation and pipe support allow the check to move freely without imposing stress on the valve.
PVC body; EPDM seat; no metal parts.
Pressure: Maximum pressure at 23°C: 1034kPa open (full flow); 517kPa closed (back pressure).
Follow the flow arrow and keep the valve upright in horizontal installations. Vertical installation requires upward flow. Limit flow velocity to 1.5m/s. These valves are not suitable for compressed air or gas.
Connections: 25mm (1") slip x slip socket connections.
