Valves for the Fire Industry
At Rendifield, we understand that reliability in high-risk environments is non-negotiable. That’s why our specialised range of fire industry valves is engineered to meet the critical demands of fire protection systems. Designed for fast response, durability, and compliance with international safety standards, our fire valves support applications across commercial, industrial, and municipal settings — ensuring safe, controlled flow when it matters most.
Key Features
- High Pressure & Temperature Ratings
- Minimum 175 psi (12 bar), up to 300 psi (20–21 bar) for valves > DN300
- Suitable for temperatures typical in emergency systems
- Quick & Smooth Operation
- Valves like OS&Y and control gate types close slowly (≥5 seconds) to prevent water hammer
- Features like indicating stems provide clear open/closed status
- Standards Compliance & Listing
- UL-listed / FM-approved valves with compliance to NFPA 13, 14, 20, 25
- Manufacturers (e.g., OCV, NIBCO, Victaulic) provide fire-rated valve lines
- Variety of Valve Types
- Ball Valves: Fast shut-off for test/drain lines; full bore designs
- Butterfly Valves: Compact, manual-indicating, suitable for control and tank systems; pressure ratings up to ~300 psi
- Gate Valves (OS&Y): Low head loss control valves with indicating stems
- Check Valves: Swing, dual‑door, tilting‑disc; prevent backflow in sprinkler risers
- Pressure-Reducing & Relief Valves: Protect system integrity in high-pressure zones
- Air/Vacuum & Level Control Valves: Prevent surge, cavitation; maintain pressure/hydraulics (Victaulic, Val-Matic)

Main Applications
- Sprinkler & Standpipe Systems: Control, isolation, and backflow prevention (control gates, check valves, butterfly valves).
- Fire Pump Assembly: Suction/discharge control and test lines featuring OS&Y, gate, and ball valves.
- High-Rise Pressure Management: Pressure-reducing valves for floor zones in tall buildings.
- Fire Water Storage Tanks: Butterfly valves for manual control and tank isolation.
- Air/Gas Relief Systems: Air release valves to expel trapped air preventing system damage
