Critical Valve Requirements

FM Global or UL listing mandatory for all valves on automatic sprinkler systems (NFPA 13 Clause 6.1) - unlisted valves are not accepted by insurance underwriters
OS&Y (Outside Screw and Yoke) design mandatory for sprinkler system control valves - the screw position provides immediate visual indication; alternatively, post-indicator or wall-indicator valve types are used outdoors
Supervisory tamper switch mandatory for all fire system valves - connected to fire alarm panel to alert when valve is partially or fully closed
No pressure drop - full-bore gate valves only; no globe valves on sprinkler mains (excessive pressure drop reduces sprinkler design density)
IS 15105 compliance for Indian projects - Indian standard for fire fighting valves; requires BIS certification for some valve types
Firewater main valves must be car-sealed open (CSO) or locked open - cannot rely on procedural controls alone

What certifications are required for fire protection systems valves in Yeosu?
For fire protection systems in Yeosu, the applicable standards are: NFPA 13 (Sprinkler Systems), IS 15105 (India Fire Valve), UL 262 / FM 1210 (Gate Valves), UL 668 / FM 1112 (Butterfly Valves), EN 1074-6, AWWA C509 / C515, IS 5290 (Fire Hydrant).

What is the delivery time for fire protection systems valves to Yeosu?
Standard stock sizes: export documentation and delivery to Yeosu in 7–14 business days. Custom sizes and special materials (Duplex, Hastelloy, P91): 4–8 weeks manufacturing lead time. Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
Why must fire protection valves be FM or UL listed?
FM Global and UL (Underwriters Laboratories) are independent testing organisations that verify that fire protection equipment performs as specified under fire and flow conditions. Insurance companies (FM Global insures many large industrial facilities) and building codes (NFPA 13) require listed equipment because unlisted equipment has not been tested to a known standard - an unlisted valve might fail to open in an emergency, potentially causing catastrophic loss. In India, IS 15105 provides the equivalent national standard, and BIS-certified valves meet IS 15105 requirements.
What is the difference between an OS&Y valve and a post-indicator valve (PIV)?
Both are tamper-indicating valves used as fire system control valves. OS&Y (Outside Screw and Yoke) gate valves show valve position by the exposure of the threaded stem - when the stem is visible (screwed out), the valve is open. They are used indoors (inside riser closets, valve rooms). Post-Indicator Valves (PIV) are used outdoors - a cast iron post extends from the buried valve with a window showing 'OPEN' or 'SHUT'. PIVs don't require an above-ground valve room and are preferred for large outdoor industrial complexes and warehouses.
