The first Check-All Valve was
designed and built for use as a pump foot valve in 1958.
Soon, Check-All grew from one valve to many series of valves; from one
to multiple uses; from one material to a wide variety and from one man
to a factory.
Today 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 flanged connections and with pressure ratings from full vacuum to
10.000 PSI.
Located in West Des Moines, Iowa,
Check-All uses the latest technology to design, test and manufacture
each valve. From the oldest standard lines to the newest patented
innovations, Check-All Valve is THE SOURCE for your check valve needs.
While the check valves are often used as vacuum breaker or pressure
relief devices, they are the only company dedicated solely to the
design and manufacture of high quality, innovative check valves.
