Pipe joining specialist Victaulic has launched a new range of FireLock NXT dry, alternate (wet/dry), wet, deluge and pre-action devices for fire protection systems. The company says they are quick and easy to fit and claims they have the smallest installation footprint in the industry.
FireLock NXT devices are rated to 20.65bar/ 300psi (series 764 rated to 16bar/232psi by LPCB) and are available in sizes ranging from 40mm to 200mm. With an integral Victaulic-patented low pressure actuator, they all operate at 0.89bar/13psi pressure regardless of application, due to an eliminated air-to-water differential, ensuring faster water delivery to sprinkler systems. In addition, each valve has a pre-set air supervisory switch, speeding up the installation process and eliminating the potential for human error.
The innovative diaphragm design, the one-piece design of the air feed manifold and combined check valve, strainer and restrictor – as well as the reduced size of the air compressor – all contribute to the small footprint. In addition, there are fewer moving parts and easy-to-access components.
The Firelock NXT alternate valve not only provides both wet and dry functionality in a single valve, but also requires the adjustment of only three valves to drain and re-pressurise the system for warm or cold weather. For speedy installation, the valve (weighing as little as 43kg) also can be shipped pre-trimmed with the need for only a pressure gauge connection on arrival.
Victaulic also offers the Series 751 and 759 FireLock Alarm Check Valves for wet systems.
