Variable function voting solenoid-operated valve apparatus having air-to-move valve actuators and testing method therefore

摘要

A variable function voting solenoid-operated valve apparatus is provide, wherein the apparatus includes a first solenoid-operated valve (SOV1), a second solenoid-operated valve (SOV2) and a bypass valve (B/P) disposed in mutual fluid communication, wherein one or more of said first solenoid-operated valve (SOV1), said second solenoid-operated valve (SOV2) and said bypass valve (B/P) further comprises one or more air-to-move valve actuators; an air supply (7) for delivering a supply of compressed air to said one or more air-to-move valve actuators; a plurality of pressure sensors, including a first pressure sensor (PS1) disposed in fluid communication with said first solenoid-operated valve (SOV1), a second pressure sensor (PS2) in fluid communication with said second solenoid-operated valve (SOV2), and a third pressure sensor (PS3) disposed in fluid communication with said bypass valve (B/P); and an exhaust vent (4) for venting pressure accumulated within one or more of said first solenoid-operated valve (SOV1), said second solenoid-operated valve (SOV2) and said bypass valve (B/P) to an external environment. Numerous alternative embodiments of the apparatus and testing methods therefore are also provided.
