Description

Counterbalance valves are also referred to as over-centre valves or motion control valves. Their design permits the control of the motion of over-running loads. The valve features two ports, port-1 and port-2. The check valve ensures a free flow from the directional valve (port 2). When the load pressure at port- crosses the pressure setting, relief function is activated to relieve the flow from 1 to 2.

These compact valve operates with quick response time, ensuring load holding at "zero leakage". Negative loads are excellently controlled over the entire flow range while operating. It has low power consumption, provides pressure relief type of overload protection and tolerance to oil contamination.

These pressure compensated counterbalance valves come in various versions such as relief compensated, 3-ports atmospherically vented, 4- ports vented as per need. They also come in special setting and fixed setting versions.
