This device is designed to operate at a flow rate of 1,600 lpm and a nominal pressure of 16 bar. The mechanism, which comprises two opposing valves, also balances the pressure between the inlet and outlet. In the event of a pressure difference in the chamber, the water is immediately discharged through the vents located at the top of the body.
