Description

RK swing check valves are engineered to ensure unidirectional flow, automatically closing to prevent reverse flow and safeguard your fire protection system

Swing check valves are normally recommended for water and wastewater systems applications because of the simple construction, low pressure drop across the valve, and field serviceability

Swing check valves are available in either metal-to-metal seat or resilient seating. Resilient seated swing check valves are usually recommended for wastewater or services where dirt or other particles may be present in the fluid and positive shutoff is required.
