Valves & Actuation
Hayward Y-Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters or process equipment. Hayward Y-Check Valves operate without the need for any adjustments or settings. A plastic coil (not a spring) supports the disc inside the body. When the inlet flow stops, back pressure (a minimum of 2 psi is required) moves the disc with its elastomer o-ring onto a plastic seat - shutting off the flow.
Features
• 150 psi @ 70°F (non-shock) • Full flow design, works in any position
Wafer Check Valves
MATCO Norca is a leading supplier of high quality check valves to all phases of industry. Metal hinged dual plate check valves are designed and rated in accordance with industry (ANSI and ASME) standards.
• Minimal pressure loss. 200 psi rated @ 150°F • Minimal installation space and time • Cast iron body, bronze plates, NBR seat and stainless steel trim
• Ideal for pools, water parks and water features
Note - install minimum 5 pipe diameters downstream from pump discharge or elbow to avoid turbulence
Engineered and Flow Tested for Superior Performance
Designed for quick, positive seal-off with minimum turbulence, low restriction and maximum fluid transfer, this industrial-grade ball check valve is used in a wide variety of industrial and chemical processing applications.
Heavy-Bodied PVC or CPVC Construction
Spears True Union Ball Check Valves never rust, scale or pit, providing exceptional chemical and corrosion resistance. Strong buttress-type threads on the union nuts allow higher pressure-handling capability and quick in-line installation and servicing.
- Spears computer-engineered design provides superior fluid flow with minimum turbulence. Eliminates “chatter” often encountered in ball check valves.
- Maximum Internal Pressure of 235 psi at 73°F for the most demanding applications of 1/2" - 4" valves.
- All Spears True Union Ball Check Valves are NSF Certified for potable water use.
