QPV1T | Internal Sense
The QPV1 is a complete closed loop control valve consisting of valves, manifold, housing and electronic controls. Pressure is controlled by the use of two solenoid valves. One valve functions as inlet control, the other as exhaust. The inlet valve operates proportionally to the command supplied by the control circuit. This variable orifice effect allows precise control of pressure at low flow conditions and avoids the digital steps of traditional ON/ OFF solenoids. The exhaust solenoid is a standard ON/OFF solenoid and allows excess media to be vented from the system.
QPV2T | External Sense
The QPV2T has similar operation to the QPV1T, but uses an external pressure transducer to maintain pressure downstream should the application need to be controlled further downstream from the QPV2T. This external feedback is sent to the electronic controls. This feedback signal is compared with the command signal input. A difference between the two signals causes one of the valves to open, allowing flow in or out of the system. Accurate pressure is maintained by controlling these two valves. The feedback signal can come from a variety of different transducer types.
