BUCHER SECTIONAL VALVES

Sectional Directional Valves

Bucher Series HDS

Bucher HDS

HDS series directional control valves represent a flexible unit construction, the elements of which may be combined into one valve unit as required.

They are available in 5 different sizes, and with parallel, series, series/parallel or load sensing circuitry. In addition, the range includes inlet and intermediate flow control sections with either manual or electro-proportioanl operators. Where accurate control of speed and actuator position is needed, the valves satisfy the most complex hydraulic circuit requirements.

Advantages

  • Wide choice of hydraulic circuitry and maximum flexibility
  • Electrical and mechanical operators can be combined in the same valve
  • Spools can be customised with differing metering ranges
  • By-pass solenoid valve and manual safety control in order to prevent unauthorised movement of actuators
  • Wide range of valve sections with flow control and priority flow control
