Sun Hydraulics CBCALAN Counterbalance Valve
Sun Hydraulics CBCALAN Counterbalance Valve
Product Description :
- It is a type of valve used in hydraulic systems to provide control over the motion of loads, particularly in applications involving cylinders or motors.
- They 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.
