3:1 pilot ratio, standard capacity counterbalance valve
SERIES 3/ CAPACITY:240 L/min./ CAVITY:T-17A
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.
Other names for this valve include motion control valve and over-center valve.
