The LCBEG-J is an L Series counterbalance cartridge valve with a 4.5:1 pilot ratio, a 1,000 to 5,000 psi spring range and a 31 gpm flow rating. It holds a cylinder or motor load in position and meters it down under control when the directional valve calls for movement.
Oil passes freely to the actuator through the built-in check. Return flow from the load side stays blocked until the combined effect of load pressure and pilot pressure exceeds the spring setting. With a 4.5:1 pilot ratio, each psi of pilot pressure counts about four and a half times toward opening, so the valve opens with a relatively low pilot signal.
Rated operating pressure is 5,076 psi, and the listed temperature range is -30°F to +250°F. The body is anodized aluminum alloy, which keeps the cartridge light.
The J spring option adjusts from 1,000 to 5,000 psi. Set the valve above the highest pressure the load can produce, and stay within the 5,076 psi rating. Size the valve so 31 gpm covers the peak return flow from the actuator, including any area ratio gain on the rod side of a cylinder. The cartridge installs in a manifold or line body machined for its cavity.
