Why You Should Choose CHEXTER™

The CHEXTER™ check valve is a self-actuating valve that responds automatically to changes and pressure and flow within a system. Its slim face-to-face dimension saves space by allowing the valve to fit in close piping arrangements.

There is only one moving part, the eccentrically mounted, contoured disc that opens at very low differential pressure. It also adapts to all flow conditions and closes prior to reverse flow in the system, thereby preventing water hammer. The eccentric mounting and contoured design yield flow coefficients much higher than most check valves.

Interchangeable and field-replaceable parts allow for a variety of seating options that include metal-to-metal, PTFE, Viton® and Buna-N.

CHEXTER™ available complete with companion flanges,
studs, nuts and gaskets, fully assembled as unit.

Typical uses are on oxygen systems, boiler feed lines, water filtration, centrifugal pump and compressor systems, loading dock lines, ship air conditioning systems and other gas and liquid applications. Approved for use by the U.S. Navy, the U.S. Coast guard, U.S. Air force and N.A.S.A.

Utilities

Used on gas and liquid pipelines from the well to city distribution systems. Meets all utility industry requirements for performance, giving water, gas and compressed air lines positive backflow protection.

Process Industries

Effectively handle corrosive flows in all types of process plants including refineries, chemical and petrochemical, textile, paint, plastics, food processing, paper and pulp, mining and explosives. A broad combination of metal trims allows quick selection of the right valve for the application.


Operation


Valve Open

The contoured disc of the CHEXTER™ lifts easily off the seat to open the valve. The airfoil design of the disc allows it to "float" on the flow. Rugged disc stops built into the body position the disc for optimum flow characteristics. The large body cavity helps minimize flow restriction. The valve functions smoothly and silently in both horizontal and vertical up-flow lines.

Valve Closed

The CHEXTER™ disc has definite design advantages: it is counterweighted, spring-loaded, and mounted eccentrically. As flow decreases, the disc starts closing and seals before reverse flow takes effect. Back pressure against the disc moves it across the soft seal into the metal seat for tight shut off.
