Swing Check Valve
Compact swing check valve for general water, oil, and gas service, available with metal or soft seat.
Inquire NowProduct Overview
The swing check valve uses a hinged disc that swings open under forward flow and closes under gravity and reverse flow. Its simple, robust design has decades of proven reliability in water, HVAC, and process service.
Available with metal-to-metal seat for high temperature or soft EPDM/NBR seat for tight shutoff, the valve is a versatile choice for general-purpose non-return duty.
