Check-All Valve

In the beginning . . . the first Check-All® valve was designed and built for use as a pump foot valve; the year was 1958. Since then Check-All® has grown from an idea to a reality; from one valve to many series of valves; from one use to multiple uses; from one material; to a variety of materials and from one man to a factory.

Design Features — The complete line of Check-All® valves are in-line spring-loaded poppet-type check valves. Many series are available to provide check valves for practically every service application. Check-All® valves are available with metal to metal or soft seats. Sizes range from 1/8” NPT to 20 inch flange connections. Pressure ratings are available from full vacuum to 10,000 psi.

Special materials include Titanium, Alloy C-276, MONEL® 400 or Alloy R405 , Alloy 20 and many others. A wide range of spring settings is available for all valves.
