Check-All Valves For Water, Oil and Gas Applications. 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. Check-All has grown in all respects - but one element remains the same - SERVICE TO EACH CUSTOMER. They will never permit this to change.
Design Features - The complete line of Check-All Valves are in-line spring-loaded piston-type check valves. Many series are available which provide check valves for practically every service application. All valves are available with metal-to-metal or soft seats. Sizes range from 1/8 NPT to 20 inch flanged connections. Pressure ratings are available from full vacuum to 10,000 psi. Special alloys available are Titanium, Hastelloy, Monel, Alloy 20, Nickel, lnconel and many others. A wide range of spring settings is available for all valves. FEP encapsulated springs are available for special corrosion applications.
The following are some of the reasons Check-All® is an outstanding check valve:
SILENT - engineered for silent operation! Check-All valves close quickly and smoothly to minimize hammer noise.
ORIFICE SIZE - engineered from experimental data to give a minimum pressure drop over the full flow range of the valve.
BASIC DESIGN - streamlined so that fluid flows through the valve over smooth contoured surfaces with a minimum change in direction.
INDUCED TURBULENCE - on seating surfaces just before the valve closes, insures positive sealing by removing minute foreign particles suspended in the fluid.
SEATING SURFACES - on all metal valves are mated and precision lapped to insure effective sealing. The mated parts remain mated through the assembly process.
DESIGNED - to function equally well in either a vertical or horizontal position, with proper spring selection.
DESIGNED - to reduce installation costs. Insert series Check Valves easily fit into existing line components that reduces both initial cost and installation time.
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.
