Check-All check valves are available in a wide range of spring settings as well as body and seat materials to meet most application needs. They close quickly and smoothly to eliminate water hammer. Our spring check valves are engineered for silent operation. With proper spring selection, they will perform equally well in either a vertical or horizontal position.
