6. Overall System Diagram

Figure 1

The ADV consists of a pressure balanced valve which opens periodically to allow fluid from the discharge

line to bypass the discharge check valve and flow back into the pump head. The valve is actuated by a solenoid

controlled by a solid-state timer. The ADV Valve Assembly incorporates a dual sealing design to insure the valve

function even if the Primary Bellows seal fails. The Leak Detection Port (1/8” NPTF) allows visual indication of a

Bellows failure while allowing the ADV to keep functioning. At the discretion of the user, this port may be used to

pipe any leakage to a safe vessel or a leak detection device.
