Description
Features & Benefits
- Three Modes of Operation:
- Automatic – Controls pre-set pressure from 15 – 115 psi (1.0 – 7.9 bars)
- Open – Full flow to rated capacity:
- WPRV/3 – 500 gpm (1,893 Lpm) w/ 7 psi (0.5 bars) drop
- WPRV/4 – 1,500 gpm (5,678 Lpm) w/ 20 psi (1.4 bars) drop
- Closed – Bubble tight shut off
- NFPA 1901, 14-6 compliant – Exclusive WPRV pilot control also provides bubble tight shut off to comply with NFPA 1901,19-3.6, TIA 99-1 preventing foam solution back flow into a potable (hydrant system) water supply
- Pressure ratings – 230 psi (15.9 bars) max. and 20 psi (1.4 bars) Min. (prevents reducing hydrant system pressures below 20 psi or 1.4 bars)
