The following is the introduction of high quality Hispeed® PN16 Wet System Valve, We supply PN16 Wet System Valve.The Wet System valve works as a check valve by preventing the reverse flow of water from the system piping to the water supply. The valve is trimmed with a water bypass line,which has an in-line swing check valve. The bypass line allows pressure surges to enter the system and to be trapped above the alarm check valve's clapper without the clapper lifting and causing false alarms.When significant flow of water occurs, such as from an open sprinkler, the valve's clapper lifts and allows water to enter the system. Simultaneously, water enters an intermediate chamber, which allows the water to activate an alarm either through a water motor alarm or through a water pressure alarm. These alarms continue to sound until the flow of water is stopped.We are expecting to become your long term partner in China.
