Long description
Equalising valves or brake valves provide controlled movement, stopping and holding of loads. They prevent the lag of movements (negative load) and protect the installation against external forces (anti-shock). Overcentre valves provide controlled initiation and stopping of a movement, while holding the load at rest. When mounted directly on the cylinder or motor, they also function as hose breakage protection.
