The BLG balancer valv is a multi pressure control valve which supplies freely slected balanced pressure to the auxiliary cylinder for smoth ascent/descent drive operation of large load tables, etc. The valve integrates reducing and counterbalance (relief) functions and balance pressure can be freely changed by handle operation in the case of increasing or decreasing load.
Compared to conventional circuits which utilize reducing valve, counterbalance (relief) valve, and check valve, these functions can be integrated into a single valve with the BLG.
