Gala OS&Y Resilient Seated Gate Valve – Flanged MJ Ends
The Gala OS&Y (Outside Screw & Yoke) Resilient Seated Gate Valve is a heavy-duty isolation valve designed for fire protection systems, water distribution networks, and industrial piping applications. Engineered for reliable shutoff performance under high-pressure conditions, the valve features a rising stem design for clear visual indication of open or closed status.
Manufactured from high-strength ductile iron with fusion-bonded epoxy coating, the valve offers excellent corrosion resistance, long service life, and leak-proof operation. The resilient EPDM-coated wedge ensures bubble-tight sealing, making it ideal for fire sprinkler and suppression systems.
