Automation Components Inc (ACI) EPW2GFS Control 318423-701 The robust 5/8 inch orificeThe Automation Components Inc (ACI) EPW2GFS Control is a high performance PWM to pneumatic transducer designed to convert pulse width modulation or digital signals into a proportional pneumatic output (0 to 20 psig). This dual valve pneumatic interface is engineered with a fail safe 3 way branch exhaust valve that automatically depletes branch line air during a power failure, ensuring system safety. The unit features jumper selectable input timing and
