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

Liquid-filled gauges are recommended for use in applications which are subject to pulsating pressures or mechanical vibrations. Stainless steel gauges are suited for applications where conditions such as corrosive fluids, or environments with pulsations or vibrations, are present.                                         

Specifications
Socket Material: AISI 316L Stainless - 1/4" NPT
Dial: 2.5" White Aluminum with black markings
Case: AISI 304 Stainless, Plexiglas window

The Penguin plastic gauge guard is a unique, compact, molded design consisting of two threaded fluid chambers. There is no possibility of leakage due to uneven screwed components. Each piece contains a matching groove which confines the true o-ring incorporated on the OD of the impermeable diaphragm. A bleed plug and o-ring are included in the design for proper filling or the incompressible liquid in the gauge side chamber. This prevents air entrapment, thus providing an accurate reading with no needle vibrations.

Features
• Choice of materials CPVC, PVDF or Polypropylene   • Impermeable and resilient Viton diaphragm   • 1/4" FPT instrument (gauge) connection   • 1/2" FPT bottom system connection   • No metallic fasteners to corrode
