Counterbalance Valves

Counterbalance valves are also known as over-centre valves or motion control valves. They are designed to control the motion of overrunning loads.

Technical requirements:
* Load holding at "zero leakage"
* Excellent control of negative loads during operations and throughout flow range
* Quick response time
* Pressure relief protection against overloads
* Energy saving
* Tolerance to oil contamination
* Compact design

The check valve function allows free flow from the directional valve (port 2); when load pressure at port 1 rises above the pressure setting, the relief function is activated and flow is relieved from 1 to 2.
Pressure compensated counterbalance valves are available in different versions: relief compensated, 3-ports atmospherically vented, 4- ports vented. Fixed setting versions available. Special setting versions available.
