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 .
Pilot assist at port ③ lowers the effective setting of the relief valve at a rate determined by the pilot ratio.
FEATURES
Counter Balance Valves should be set at least 1.3 times the maximum load induced pressure.
Back pressure at port ② adds to the effective relief setting at a ratio of ① plus the pilot ratio times the back pressure.
Reseat exceeds 85% of set pressure when valve is standard set.
Settings lower than the standard pressure may result in lower reseat percentage.
