MB Counterbalance Valves with 3 Ports – Load Control

Load control counterbalance valve (MB) include:

  • Lowering velocity control and stationary load holding
  • Providing protection against hydraulic line failure and pressure shocks when placed next to actuator
  • Suitability for diverse applications such as lifting applications, hydraulic cylinder, winches, extensible movable bridge, etc
  • A MB counter balance valve is normally used in proporational valve circuit

Specifications for Load control counterbalance valve (MB):

  • Rated flow of up to 480 LPM
  • Pressure range of 70 Bar- 350 Bar
  • Leakage of up to 5 drops per min at Reseat at 85% of setting

Special features of MB valves:

  • Stable at wide range of flow, especially at low flow
  • Port 1 seats as a poppet valve and modulates as a spool valve, allowing these valves to modulate over a broader range of flows than the standard counterbalance (CB) designs. The longer stroke allows a uni-directional damping device to smoothen the opening and let the valve close quickly.
