OS&Y Resilient Seated Gate Valve
The BLAZE OS&Y Resilient Seated Gate Valve is designed for high performance in potable water systems, HVAC, mechanical services, and industrial applications. With an outside screw and yoke (OS&Y) design, it provides clear visual indication of valve position, enhanced maintenance accessibility, and reliable shut-off capability. Constructed with a durable ductile iron body and coated with Fusion Bonded Epoxy (FBE) in RAL 5015 blue, this valve is built for long service life, corrosion resistance, and hygienic performance. A resilient seated, fully encapsulated wedge ensures tight sealing and smooth operation.
