Description
Fixed-setting, 3-port Counter Balance Valves with pilot assist function similarly to the adjustable versions except the fixed setting is pre-set to a nominal value.
Operation
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.
