Feature

RV Cylinder type pneumatic control valve is produced in accordance with international standard (ISO 6431). QGB pneumatic actuator is powered by compressed air and outputs thrust or pull force through rectilinear motion of piston and piston rod to open or close the valve with linear travel, The pneumatic control valve is provided with an intelligent electro-pneumatic valve positioned to receive a 4-20m ADC control signal of adjuster from computer, and at the same time outputs a 4-20m ADC valve position feedback signal corresponding to actuator travel in order to adjust the opening of valve by remote control. The pneumatic actuator may adopt double acting form: spring return single action form, hand wheel form etc.
