The Helesul Double Counterbalance Hydraulic Valve is widely used in lifting, steering, and implement-holding systems for combine harvesters, self-propelled sprayers, cutting platforms, agricultural cranes, and load-handling equipment. Its dual-locking function is essential in circuits where two cylinders operate in a synchronized manner, such as booms, articulated arms, and tilting systems.
In sprayers, for example, the valve ensures that boom arms remain in the adjusted position even in the event of an accidental engine shutdown or hose rupture, preventing equipment damage and reducing risks to operators. In combine harvesters, it ensures that headers and platforms do not experience unexpected drops during maintenance or transport.
Its versatile design allows installation in both new equipment during the design phase and retrofit projects for machines already in operation, adapting to different hydraulic circuit configurations and safety requirements.
The valve operates through a pilot-operated double counterbalance system that locks hydraulic flow in both directions until a specific pilot pressure is reached. This principle ensures that the load remains suspended and stable even in the complete absence of system pressure, making it an essential component for lifting applications.
Key benefits include reducing the risk of load-drop accidents, minimizing unplanned downtime caused by hydraulic failures, and extending the service life of cylinders and hoses by absorbing pressure spikes and preventing mechanical shock.
Installation is simplified through standardized connections compatible with the main hydraulic circuits used in the agricultural industry. This reduces assembly time on production lines and facilitates field replacements. Preventive maintenance is also faster thanks to the robust design and easy access to internal components.
In daily operation, these features provide greater productivity and operational safety, allowing operators to perform lifting and load-holding maneuvers with confidence, without the need for additional mechanical locking devices or manual restraint procedures.
