ABSTRACT:
A pressure control valve and transducer package for use in combination with a pneumatic actuator which incorporates a double acting pneumatic cylinder includes, in a single multi-component unit, a valve assembly constructed for direct coupling into the pneumatic pressure loop for operating the actuator, and a second component which comprises a fixture housing one or more continuously operating sensors for measuring the pressures supplied to the opposite ends of the cylinder in the actuator and transmitting appropriate signals conveying that information to a microprocessor which in turn regulates the supply flow rate of pressure gas to the cylinder through a closed loop feedback system.
