Chexter™ Check Valves

Mueller Steam Specialty's 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.

Non-slam Sealing to Prevent Reverse Flow

• Raised face and flat face valves in 2–36in.
• Ring type joint face valves in 2–24in.
• Many types of metals and trims available
• Replaceable seal ring
• Slim body design
• Silent operation
• Low pressure drop
• Horizontal or vertical upflow services
• Lightweight, easy to install
• For gases and liquids

Commercial Construction

Economically used in chilled and hot water air conditioning systems, refrigeration and other piping and plumbing lines in multiple-story buildings, shopping centers and institutions. Meets General Services Administration requirements. Low-cost, lightweight.

Industrial and Marine

Meet rigid requirements in all kinds of industrial and marine piping systems. 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.
