Hydraulic Amplifiers

The HA series Hydraulic Amplifiers from HEINZMANN Australia provide the force to operate heavy control valves of steam turbines or fuel control linkages of large reciprocating engines. This may be done via a mechanical input (i.e. HEINZMANN all electric actuator) or via a 0 – 200 mA input signal to the built in internal actuator.
