The OS&Y Resilient Seated Gate Valve is a high-performance isolation valve designed for reliable shutoff in water supply, irrigation, and general industrial applications. Manufactured from ductile iron with fusion-bonded epoxy (FBE) coating, it provides exceptional corrosion resistance and long service life, even in harsh environments.
Featuring an Outside Screw and Yoke (OS&Y) design, this valve offers a clear visual indication of valve position while keeping the stem threads isolated from the process media, improving operational reliability and safety. The resilient EPDM seat ensures tight sealing, low torque operation, and long-term leak-free performance.
Flanged to AS2129 Table E, the valve is compatible with standard Australian piping systems. Designed for ease of operation and maintenance, it is ideal for use in water treatment plants, pumping stations, fire protection systems, and general industrial pipelines.
This valve is ideal for water supply, irrigation, fire protection, and general industrial pipelines. Its robust ductile iron body with FBE coating ensures excellent corrosion resistance, making it suitable for both above-ground and underground installations in demanding environments.
The Outside Screw & Yoke (OS&Y) configuration provides a clear, visual indication of whether the valve is open or closed. By keeping the stem threads external to the fluid, it reduces wear and corrosion, improves operational reliability, and simplifies maintenance.
The resilient EPDM seat ensures bubble-tight sealing and low operating torque, providing leak-free performance even under low-pressure conditions. EPDM material offers excellent resistance to water, chemicals, and moderate temperatures, enhancing valve longevity.
The valve body is constructed from high-strength ductile iron coated with fusion-bonded epoxy (FBE) for corrosion protection. The EPDM-coated resilient wedge ensures tight sealing, while the handwheel-operated OS&Y stem provides smooth, reliable operation. Flanged ends are machined to AS2129 Table E standards for secure connections in standard Australian piping systems.
The OS&Y design and handwheel operation allow easy inspection and control of the valve’s position. The flanged design simplifies installation and removal without disturbing adjacent piping, and the FBE coating and resilient seat minimize maintenance requirements while providing long service life.
