Counter Balance Valve 136937350 CP440-4-B-0-E-B-350-3.0-015

Product Overview

This Counter Balance Valve is a high-performance cartridge valve designed to provide modulated motion control and leak-free load holding in hydraulic circuits. This Counter Balance Valve effectively prevents loads from drifting or dropping due to spool leakage or unexpected hose failure. It is an essential safety and performance component for operators of heavy machinery requiring precise hydraulic actuator control.

Key Features & Performance

• Three-ported externally piloted design for precise pressure-sensitive operation
• Low-leakage check section ensures stable load holding and prevents drifting
• Integrated relief valve activates when load pressure exceeds the specific setting
• Hydraulic vent feature allows for consistent performance in various circuit configurations
• Durable construction maintains reliability under high-pressure operating conditions

Fitment & Compatibility

• Danfoss Hydraulic Systems
• Comatrol Hydraulic Assemblies
• General 12-size Cartridge Cavities

Common Uses

• Load holding for aerial lifts, cranes, and winches
• Motion control for over-running loads in hydraulic motors
• Hose-break protection when installed directly near an actuator

Frequently Asked Questions

Q: How does this valve prevent a load from falling if a hose breaks? A: The valve is designed to block flow from the actuator until pilot pressure is applied, acting as a safety lock in the event of a line failure.

Q: Can this be used for bi-directional load control? A: While this is a single valve typically for unidirectional loads, dual configurations can be used for bi-directional applications like motors.
