CPF Industriale Srl is pleased to be the first manufacturer to introduce into the European market the first valve complete of trim alarm, entirely produced in Italy, certified CE 1922 in conformity with the UNI EN 12259-2 norm. The wet valves are used in the water fire extinguishing systems with water presence upstream and downstream. They mainly have two purposes: the first one is to allow the passage of the water in the event of break-up of one or more sprinklers, the second is the activation of an alarm that doesn’t depend from power supply. Additional alarm systems can be implemented by using pressure switches. Wet valves characteristic is the extreme simplicity to access to the clappet for the inspection and for the starting. With the system idle, the water in the distribution pipelines maintains the disc of alarm valve in closed position. With water’s spillage from one or more sprinklers, the pressure in the pipeline decrease . Therefore the pressure of the feeding water prevails and determines the automatic opening of the disc necessary to feed the working nozzles. Once the fluid flows, the valve signals the opening of the sprinklers operating a hydraulic bell. With the use of the delay room of the possibilities of false alarms due to the normal pressure variations in the hydraulic network are eliminated. The purpose is that to protect the building, the people and the content from the danger of fi re. It can cover up to 12.000 sqm. of surface in one fi re compartment only and it can be fed both by a system of water pumping and by the aqueduct network. C.P.F Industriale has decided to propose a preparation trim/ wet valve at variable pressure with test valves of alarm muting in view to allow the technicians to try the plant once installed getting the test and inspection certifi cation of the plant from the responsible persons.
