Material of Construction — Resilient seated (water service)
- Body & bonnet: Ductile iron DI, internally & externally epoxy / CED coated
- Wedge: Ductile iron, fully encapsulated in EPDM rubber
- Stem: Stainless steel SS 410 / SS 304
- Stem nut: Brass / bronze
- Stem seal: Multiple EPDM O-rings, replaceable under pressure
- Bonnet bolts: Stainless steel SS 304 (encapsulated head)
- Operating element: Hand-wheel (above ground) / cap-top (buried)
Material of Construction — Metal-seated (process / steam)
- Body & bonnet: Cast steel WCB / WC9 / SS 304 / SS 316
- Wedge (solid / flexible): Forged steel / SS, hard-faced (stellite)
- Seat ring: Hard-faced (stellite) — renewable
- Stem: Stainless steel SS 410 / SS 316
- Gland packing: Graphite / PTFE braided
- Bonnet joint: Bolted with spiral-wound gasket
- Stem type: OS&Y for visible position indication
Salient Features
- Full-bore design — minimal pressure drop when fully open
- Bi-directional flow capability
- Resilient seated (rubber wedge) — 100% bubble-tight shutoff
- Metal-seated for high-temperature & abrasive service
- Non-rising stem (NRS) — compact in buried installation
- OS&Y variant for above-ground installations (visible position)
- EPDM o-ring stem seal — leak-free, replaceable
- Internal & external CED / epoxy coating (water service)
- Suitable for potable water (WRAS / NSF on request)
- Conforms to IS 14846 / EN 1171 / API 600
Applications
- Municipal water supply mains (resilient seated)
- Wastewater treatment plants
- Fire-fighting isolation valves
- Industrial mainline isolation (on/off only)
- Refineries & process plants (metal-seated)
- Building services & plumbing mains
- Pumping station inlet & discharge isolation
- Underground & buried installation (cap-top)
Not suitable for throttling / flow control — use only fully open or fully closed.
For buried installation, use cap-top with extension spindle and surface box.
