E-CBIH 10:1 PILOT RATIO, STANDARD CAPACITY COUNTERBALANCE VALVE



SYMBOL

 

OPERATION

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.

 

SPECIFICATIONS:

Max.Setting: 350 bar (5000 psi)

Maximum Recommended Load Pressure at Maximum Setting: 270 bar (3850 psi)

Flow: 120 gpm (480L/min)

Internal Leakage: 5 drops/min

Pilot Ratio: 10:1

Temperature: - 30°C to 100 °C (with Standard Buna N seals)

Filtration: 20μm or better

Cavity: SUN T-19A

Installation Torque: 465 – 500 Nm

 

FEATURES:

l  Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.

l  Full clockwise setting is less than 200 psi (14 bar).

l  Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.

l  Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages.

l  Factory Pressure Settings Established at 30cc/min (2 in³/min).
