UL / FM OS&Y Gate Valve Manufacturer in India
Outside screw & yoke fire-main gates with verifiable UL and FM listings — not generic “fire duty” castings.
Why OS&Y on fire pumps and risers
OS&Y rising stem shows open/closed position from a distance and is required on many NFPA 20 fire-pump suction/discharge and NFPA 13 riser control locations. Pair with supervisory switches where the spec demands electronic monitoring.
