Valves for HVAC & Building ServicesTirunelveli

Tirunelveli anchors Tamil Nadu's southern wind energy corridor — the Aralvaimozhi Pass and Sankarankovil wind belt host over 2,200 MW of installed capacity (Suzlon, Siemens Gamesa, and Envision turbines), where hydraulic pitch control circuits, gearbox cooling systems, and fire suppression lines require high-cycle SS 316 ball valves, butterfly valves rated for −20°C ambient, and API 607 fire-safe designs; Seshasayee Paper & Boards and local pulp mills drive demand for rubber-seated butterfly valves for pulp slurry, blow-heat recovery, and black-liquor circuits; the SIPCOT estate at Valliyoor houses chemical and auto-ancillary manufacturers requiring Class 150–600 gate and globe valves with full material traceability.

Butterfly, ball, globe, and gate valves for HVAC chiller systems, cooling towers, AHUs, fire suppression, and building plumbing — ductile iron and stainless steel.

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.
