COUNTERBALANCE VALVE CP441-1-B-0-E-B-XXX-4.5-015
CP441-1, Hydraulic Vent Valve
Operation
This 3-ported, externally piloted unit is a 12-size cartridge style, low leakage counterbalance valve with hydraulic vent. The check section allows free flow from the directional valve (port 2) to the load (port 1), while normally blocking flow from port 1 to port 2. Reverse flow is blocked until pilot pressure is applied at port 3. When the load pressure at port 1 rises above the pressure setting, the integral relief valve is activated, and pressure is relieved from port 1 to port 2.
Applications
Single counterbalance valves are normally used when the load is unidirectional, such as aerial lifts, cranes, or winches. In load holding applications, they can be used as hose-break valves when installed near or within an actuator. Dual valves can be used for controlling loads bi-directionally in motor applications, or for cylinders going over center.
