Check Valves: Full-Service Valve Series
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. Positive sealing is achieved by turbulence introduced upon closing. This agitation removes minute foreign particle suspended in the fluid near the valve seat. The seating surfaces are parallel to each other. thereby eliminating the excessive wear occurring in plug, cone and ball seats.
