The LCBCA-H is an L Series counterbalance cartridge valve with a 3:1 pilot ratio and a 1,000 to 4,000 psi spring range. A counterbalance valve holds a load in place and controls its descent, so a cylinder carrying an overrunning load moves only when the circuit commands it.
In a typical circuit, oil flows freely to the actuator through the valve’s internal check. Flow back out of the actuator stays blocked until load pressure plus pilot pressure overcomes the spring setting. The 3:1 pilot ratio means each psi of pilot pressure counts about three times toward opening the valve, so a modest pilot signal releases the load in a controlled way.
The body is anodized aluminum alloy. The valve is rated for 3,100 psi operating pressure and a temperature range of -30°F to +250°F. The H spring option adjusts from 1,000 to 4,000 psi. Set it above the highest pressure the load can generate, and keep the setting within the 3,100 psi operating rating of the valve.
The cartridge installs in a manifold or line body machined for its cavity. Confirm the cavity size and your circuit’s peak flow against the valve before ordering, and check the setting after installation with a gauge on the load side.
