Counterbalance Valve

Counterbalance valve returns hydraulic fluid once pressure is present on hydraulic supply side of valve. Counterbalance valve works in conjunction with hydraulic system flow setting. When system hydraulic flow is changed, counterbalance valve requires adjustment.

A counterbalance valve is required when machine hydraulic system does not regulate return flow. A counterbalance valve is not required when utilizing an external valve.

For optimal and consistence performance, install and properly adjust counterbalance valve.

The following machine models utilize CAN-based selective control valves (SCVs) requiring a counterbalance valve and must be adjusted for optimal performance:

• 8030 series wheel tractors (S.N. 40001–).
• 8030 series track tractors (S.N. 905001–).
• 9030 series wheel tractors (S.N. 013000–).
• 9030 series track tractors (S.N. 911000–).
• All 7R, 8R, 8RT, 9R, and 9RT series tractors.
