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.

HEINZMANN Australia offers a cost effective direct “bolt-on” replacement for Woodward governors. For direct allocations see table overview.

Key features:

  • Product accepted by SNM, Allen (WEIR) & NG steam turbine manufactures
  • Main housing made from high spec 500-7 Nodular Graphite Iron (Ductile Iron)
  • Power piston & output shaft made from EN36, for extra durability and reliability
  • Output shaft has oil fed support bush, for improved side loading
  • High efficiency oil motor, excellent performance even in harsh oil conditions
  • Internal actuator oil accumulator, for improved stability (“E” only)
  • Optional oil filter, for improved service life and reliability (“E” only)

Please contact Heinzmann Australia for a price and availability.
