• Check-All Valve

  • Since their inception in 1958, Check-All Valve has expanded from producing one valve with one material to manufacturing a series of valves in a wide range of materials. Many companies manufacture check valves in addition to other product lines; however, Check-All Valve is dedicated solely to the design and manufacture of spring loaded check valves.



  • Silent

    Engineered for silent operation. Check-All valves close quickly and smoothly to minimize hammer noise.


    Spring Loaded

    Functions 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.



    Designed to reduce maintenance costs, the Check-All design is simple, rugged and efficient. The seating surfaces are parallel to each other, thereby eliminating the excessive wear occurring in plug, cone, and ball seats.
