IMPACT™ - Spring Assist
In a failsafe actuator compressed air inside the actuator preloads the springs. During normal
operation, each time the solenoid valve is tripped the compressed air is released into the
atmosphere through the solenoid valve’s exhaust port.
SPRING ASSIST
The patented IMPACT™ unit diverts part of this energy to the spring chamber in order to boost
the torque of the actuator by at least 50%.
The IMPACT™ also functions as a Breather Block that isolates the spring chamber from the
atmosphere, and as a check valve that ensures that the temporary reduction of the compressed
air pressure does not trigger movement of the valve and actuator to the mid-position.
The IMPACT™ is used for on/off systems only, and cannot be used for control applications.
