Product Description

This OS&Y Rising Stem Gate Valve is engineered for reliable isolation control in fire protection systems and industrial water supply networks. The outside screw & yoke (OS&Y) design provides clear visual indication of valve open/close status, making it ideal for safety-critical applications such as sprinkler systems, hydrant loops, fire pump rooms, and industrial piping.

Constructed from high-strength ductile iron with stainless-steel internal components, the valve offers excellent durability and corrosion resistance.
The resilient-seated wedge and EPDM sealing ensure tight shutoff performance, while the fusion-bonded epoxy coating (inside and outside) enhances long-term protection against corrosion.

The valve conforms to AWWA, BS, ANSI, and EN standards and is available with flanged and grooved ends to suit multiple piping requirements.
