TRUE UNION BALL CHECK VALVE
FEATURES & BENEFITS
The True Union design provides easy access for in-line installation and servicing. The True Union ball check valve is designed for quick, positive sealing with minimal turbulence, low restriction, and efficient fluid transfer. Ball check valves prevent backflow in piping systems. They are installed to protect pumps, filters and other process equipment from damage. They are also effective at preventing liquid storage tanks from unwanted drain down. Used in a variety of industrial and chemical processing applications, True Union ball check valve is available in 1/2 through 2" sizes with socket and FIPT end connectors.
SPRING CHECK VALVE
Spring Check valves are used to prevent backflow and siphoning. The 1/2 lb. SS spring maintains a positive seal even when no backpressure is present. Suggested applications of Spring Check valves: pool/spa assemblies and installations, potable water systems.
FEATURES AND BENEFITS

2-psi minimum flow pressure required to open valve
-
Pressure rating: 150 psi, non-shock water at 73o F
-
Flow direction indicator molded into body for accurate installation
-
304 SS spring for corrosion resistance
-
1/2 - 2'' socket (solvent weld) end connections
-
Corrosion resistance PVC body with EPDM seal
-
Low-cost operation
SWING CHECK VALVES
1/2 - 2'' White Swing Checks
For use in irrigation, swimming pool, and commercial plumbing applications to prevent backflow. The open position allows for unobstructed continuous flow with minimal head loss, making it a favorable choice for sump pump disposal lines, sewage lift stations, and waste water lines. Swing check valves are designed for horizontal installation, but can be installed vertically with flow going upward. All check valves must be installed with the flowarrow pointing in the direction of the flow of the system. Swing check valves must NOT be installed upside-down. The flow velocity should not exceed 5 ft./second.
Features and Benefits
-
Thermoplastic design eliminates process and atmospheric corrosion.
-
Pressure rated up to 150 psi in full flow (open) position, and 75 psi in the closed position (non-shock water at 73º F).
-
High-impact PVC Type II Material
2-1/2, 3 & 4'' Gray Swing Checks
