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.
-
A Counterbalance Valve is a specialized hydraulic valve designed to control and maintain load stability in hydraulic systems. It prevents uncontrolled lowering of loads, regulates cylinder movement, and protects hydraulic components from shock and overload, ensuring safe and precise operation of lifting or lowering equipment.
-
Constructed from high-quality, durable materials, counterbalance valves provide reliable, leak-free performance in demanding industrial, construction, and mobile applications.
