Proudly Manufactured in the USA!

Whether you need a high-quality check valve for your standard application or have special requirements, make Check-All your first choice. You will find that our quality, innovation, and service will exceed your expectations. 



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 nay 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. 

Check-All Valve Manufacturing

Check-All Valve manufactures a complete line of in-line spring-loaded piston-type check valves for practically every service application. Valves are available with metal-to-metal or soft seats in sizes from 1/8NPT to 20-inch flange connections and with pressure ratings from full vacuum to 10,000 psi.
