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.
