Sun CBCALAN Standard Capacity Counterbalance Valve

Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow
from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow
from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the
pilot ratio.
