FlexJet™ Pneumatic Servo Actuators
Utilizing a single-coil design with 0-10 VDC input, this pneumatic FlexJet servo-actuator provides powerful position control up to 2” that is directly proportional to input voltage. An internal spring provides position feedback to the servo, resulting in exceptional control capabilities in a small package. Read More
Proportional Solenoid Valve
Proportional Solenoid Valve operates a single arm variable bridge pneumatic flapper valve that controls actuator position by balancing magnetic and feedback spring forces. Magnetic forces increase with solenoid thus creating the movement of the main actuator until the feedback spring force is equal to the solenoid magnetic force. The Proportional Solenoid assembly is fully integrated within the main actuator cavity thus enhancing the speed of response and overall stability of movement. The Proportional Solenoid valve offers low threshold and low power consumption of 1.5 watts max. Read More
The FlexJet servo is based on JASC’s extensive work with servos in harsh service conditions. The FlexJet servo features high contamination resistance and is a more robust design compared to traditional jetpipe servos. The FlexJet eliminates the wear- and fatigue-prone elements of the jetpipe, minimizing the effects of vibration, extreme temperature and mechanical wear, leading to a longer, more trouble-free service life.
