VCB12-CN-2-B-00-N-XXX
Product Name: Counterbalance Valve
Application:This counterbalance valve is a 12 size metric, 3-ported, externally piloted low leakage, cartridge style valve with atmospheric vent. The check section allows free _x001f_ow from the directional valve (port 2) to the load (port 3), while normally blocking _x001f_ow from port 3 to port 2. Reverse _x001f_ow is blocked until pilot pressure is applied at port 1. When the pressure at port 3 rises above the pressure setting, the integral relief valve is activated and vents the area behind the pilot piston.
Atmospheric vented valves are applied when it is not practical to connect a separate vent line to the tank. Use a single counterbalance valve when the load is unidirectional, such as aerial lifts, cranes, or winches. In load holding applications, they are suitable for use as hose-break valves when installed near or within an actuator. Dual cartridges can be used for controlling loads bi-directionally in motor applications, or for cylinders going over center. Since this valve is piloted at port 1, no cross port drilling is required when dual cartridges are mounted nose to nose in an HIC
- Product Description
VCB12-CN-2-B-00-N-XXX Danfoss Counterbalance Valve - Professional Hydraulic Control Solution
Looking for reliable hydraulic control in your industrial applications? The VCB12-CN-2-B-00-N-XXX Danfoss counterbalance valve delivers exceptional performance for your critical operations. This 12 size metric, 3-ported cartridge valve features external pilot control and atmospheric venting capabilities. You get superior load holding with minimal leakage for applications like aerial lifts, cranes, and winches. The check section allows smooth flow from your directional valve to the load while preventing unwanted reverse flow.
This advanced counterbalance valve blocks reverse flow until you apply pilot pressure at port 1. When pressure at port 3 exceeds the preset limit, the integral relief valve activates automatically. You can use single valves for unidirectional loads or dual cartridges for bidirectional motor control applications.

FAQ
Q: Can I use this valve for bidirectional motor control?
A: Yes, you can install dual product cartridges nose-to-nose for bidirectional applications.
Q: What's the advantage of atmospheric venting?
A: Atmospheric venting eliminates the need for separate tank return lines, simplifying your hydraulic circuit design.
Q: Is this suitable for hose-break protection?
A: Absolutely. Install the valve near your actuator for effective hose-break protection in lifting applications.
Q: What industries commonly use this valve?
A: Construction equipment, material handling, marine applications, and industrial machinery frequently utilize this counterbalance valve.
Q: How does the pilot control work?
A: Apply pressure at port 1 to open the valve for controlled load lowering. Remove pilot pressure to hold the load securely.
