Features and benefits

Large-stroke valves with electrohydraulic actuators

For applications, where great forces and safety are of prime importance, large-stroke valves in connection with electrohydraulic actuators are the number one choice.
On district heating applications with their demanding requirements and, generally, on large plants, electrohydraulic actuators are unmatched.
They excel in great positioning forces, robustness, spring return facility, and a host of extra functions. The electrohydraulic actuators are ideally suited for the control of primary plant and for distribution circuits with large volumetric flow.

  • Powerful for large volumetric flows and great differential pressures

  • Lower costs thanks to a robust and long service life

  • Greater safety and improved energy efficiency

  • Ideal for safety applications with spring return times below 8s

  • Safe against dirt and low noise level thanks to optimised plug design

  • Metallic sealing for temperatures up to 220 °C – thermo oil up to 350 °C


Large- and short-stroke valves with electromotoric actuators

The right combination of valves and actuators for all types of small and medium-size HVAC plants, offering straightforward planning, installation and commissioning.
Electromotoric actuators are the ideal drives for the majority of standard applications in the fields of heating, ventilation and air conditioning.

  • Excellent price performance ratio for all types of HVAC standard applications

  • Reliability and longevity thanks to a high-quality, high-performance product range

  • Low noise level for more comfort

  • Single seat, metallic seating

  • 3-port valves can be used as mixing or diverting valves
