Product Features
● The setting value of the balance valve should be at least 1.3 times of the load pressure value.
● Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure
● Reset exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reset percentages -

Counterbalance Valve 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.
