Due to our ever-increasing Residential and Domestic flow of enquiries, and the recent demands of BS 9251:2021, SEP is pleased to present our monitored ball valve in sizes from 1”/25mm up to 2”/50mm.
BS 9251:2021, section 5.15 states that “except for category 1 systems, all valves which control the flow of water to the system should be electrically monitored for the open position” – SEP can help ensure that all R&D (Residential and Domestic) fire sprinkler system installers meet this requirement, along with many others.
The valve and monitor switch can be purchased stand-alone, or as part of our resi-riser assembly, and the small assembly is simple and lightweight.
As required, the spring switch ensures that the valve is monitored to be ‘in the fully open position’ – even if slightly closed, a signal will be transmitted to the monitoring panel.
Monitored Ball Valves Comprising the Following:
- PN40 brass ball valve with BSP female threads
- WRAS-approved
- Fully lockable handle (keyed-alike padlocks also available)
- Micro-switch monitoring that the valve is fully open and not tampered with or damaged
- Flexible NC and NO connection options
- Flow switch connections also provided
- ABS enclosure with low flammability rating (UL94-HB)
- IP54-rated enclosure with min IP54-rated cable glands.
