2.3:1 pilot ratio, standard capacity counterbalance valve
SERIES 4 / CAPACITY: 480 L/min. / CAVITY: T-19A
3-Port Non-vented
3-Port Non-vented, Fixed Setting
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.
