The Model 770-U Flow Control Valve is a hydraulically operated, diaphragm actuated control valve that maintains pre-set maximum flow, regardless of fluctuating demand or varying system pressure.
Features and BenefitsThe Model 740 Booster Pump Control Valve is a 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
Features and BenefitsThe D-070 Combination Dynamic Air Valve is a unique valve operating without a float, utilizing the rolling diaphragm principle. This unique structure allows the dynamic valves to discharge air from the water system in a controlled and gradual manner, preventing slam and local up-surges. When vacuum occurs , the valves fast reaction will draw in large volumes of air into the water system, impeding down-surges and, consequently, all pressure surges in the line. The valves are normally closed when the line is not operating, thus preventing the infiltration of foreign particles and insects into the water system.
ApplicationsProtects from water hammer effects in the pipeline system , in situations such as column seperation , deep well pumping and rapid filling of mains
Operation in deep well pumpingIn deep well, the long suction pipe in the well shaft is full of air .As water is pumped rapidly up the suction pipe, air is forced through the pump air valve in great velocity .If the air valve were to slim shut suddenly , by the approaching water , instantly reducing velocity to 0, it could cause a sever water hammer or surge .
The D-43 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.
