Description

ABSTRACT:
A four-way stacking air valve with a common exhaust passageway that extends through all of the valves in a stack of valves and a pair of end plates, and with each of the valves being provided with a pair of adjustable flow control valves mounted in the valve body in separate exhaust passages connected to the common exhaust passageway. A common electrical wire passage extends through all of the valves and end plates in a stack of valves. Each of the valves has a wire tuck chamber in the valve body, on each side of the electrical wire passage. Each of the valves can be operated by one, or two solenoid operated pilot valves. The pilot air valves may employ either internal or external pilot air which is provided through common pilot air supply passageways in the valves and end plates. The pilot air is exhausted through a common pilot air exhaust passageway that extends through all of the valves in a stack of valves to exhaust ports in the end plates of the stack of valves.
