What certifications are required for hvac & building services valves in Guangzhou?
For hvac & building services in Guangzhou, the applicable standards are: ASME B16.34, EN 12266 (Industrial valve testing), UL Listed (Fire suppression valves), FM Approval (Fire protection), IS 778 / IS 780 (Indian plumbing valves), NFPA 13 (Sprinkler systems), BS 1010 / EN 12614 (Bronze valves).

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What valves are required for fire suppression systems in buildings?
Fire suppression systems (sprinkler, deluge, foam) require UL-listed or FM-approved valves for all isolation and control functions. Common types: OS&Y (Outside Screw and Yoke) gate valves — the stem position visually indicates open/closed, required by NFPA 13 for fire service mains; butterfly valves with tamper switches for zone control; check valves for backflow prevention. In India, IS 15105 and NBC (National Building Code) fire systems also reference UL-listed components.
What is an OS&Y valve and why is it used in fire sprinkler systems?
An OS&Y (Outside Screw and Yoke) gate valve has a threaded stem that rises visibly when the valve is open and is flush (retracted) when closed. This visible indicator allows fire safety inspectors, sprinkler maintenance teams, and fire brigades to confirm the valve position from a distance without opening any covers. NFPA 13 requires OS&Y gate valves (or equivalent listed valves with position indication) for all supply isolation points on automatic fire sprinkler systems.
