Silent Check Valves

Spring Loaded Check Valves

Circle Circle
Engineered for silent operation. Check-All valves close quickly and smoothly prior to reverse flow, thereby preventing water hammer noise associated with hydraulic shock. Read More! Function equally well in either vertical or horizontal position with proper spring selection. Designed with the spring upstream of the seat, strategically placing it outside any mixing and potentially aggressive solutions. Read More!

Poppet Check Valves

Inline Check Valves

Circle Circle
Designed to reduce maintenance costs, the Check-All design is simple, rugged and efficient. The seating surfaces are parallel to each other, thereby preventing the excessive wear occurring in plug, cone, and ball seats.Read More! Streamlined so that fluid flows through the valve over smooth contoured surfaces with a minimum change in direction, thereby minimizing pressure drop. Induced turbulence on the seating surfaces just before the valve closes, ensures positive sealing by removing minute foreign particles suspended in the fluid Read More!
