Foam Concentrate, Hydraulic Pilot Actuated Control Valve ZP HM
This valve is installed downstream of the foam concentrate tank and is closed in its normal, set position by the master’s main line pressure. The valve is forced open through the pilot valve by the upstream pressure of its master valve’s water mains. This allows the foam concentrate valve to open even with zero upstream line pressure, ensuring fail safe supply of foam concentrate through the foam proportioner, downstream of the main master valve.
