The LCBCA-H-8T is an L Series counterbalance cartridge valve with a 3:1 pilot ratio, a 1,000 to 4,000 psi spring range and SAE 8 body porting. A counterbalance valve holds a load in position and controls its movement when the load would otherwise run ahead of the pump flow.
The valve works in two directions. A check section lets oil flow freely into the actuator. In the other direction, flow is blocked until pressure reaches the valve setting, so the load stays where it is. Pilot pressure from the opposite actuator line assists opening. With a 3:1 pilot ratio, each psi of pilot pressure counts roughly three times toward opening the valve, so a modest pilot signal can release a load held at a higher setting.
Rated flow is 15.8 gpm, and the listed operating pressure is 3,100 psi. The spring range runs from 1,000 to 4,000 psi; set the valve above the highest load induced pressure in your circuit and inside your system’s pressure rating.
The body is anodized aluminum alloy with SAE 8 ports. Operating temperature range is -30°F to +250°F. Check the pilot ratio and spring range against your actuator and load before you order, since both affect how smoothly the load moves and how well it holds.
