Profile: Forac Ltd. manufactures compact pneumatic valve actuators for the process industry. We manufacture and supply ball and butterfly valve packages for the food, pharmaceutical and petrochemical industries. We also offer free valve sizing for modulating applications due to our economic 4-20mA positioner. The F-series is the spring return pneumatic actuator for its size, due to its large central piston and concealed springs. The DF-series takes advantage of the uniform shape of the F-series by enclosing it in a polished stainless steel dome. The dome also houses limit switches and solenoids.
