Booster Pump Control Valve IR-WW-740Q

The Model 740Q Booster Pump Control Valve is a
double chambered, hydraulically operated, diaphragm
actuated active check valve that opens fully or shuts
off in response to electric signals. It isolates the pump
from the system during pump starting and stopping,
to prevent pipeline surges.
