PNEUMATIC DIAPHRAGM LINEAR ACTUATOR
SINGLE ACTING TYPE
The PROVAL diaphragm actuator spring opposed diaphragm actuator provides precise, high thrust performance in a lightweight, compact format. The diaphragm actuators are designed afresh applying multi-spring type, so that these actuators are materialized to be miniaturized and light weighted as a new style. The PROVAL diaphragm actuators provide the operation to control the valve travel balancing between the force on the diaphragm by the signal air pressure, and the spring force.
By combining PROVAL positioner, the series brings about high accuracy of positioning.
