Overview

The HongDa Brand Hydraulic Cylinder Lock and Crane Balance Valve is a high-performance hydraulic control assembly designed for load-holding, motion control, and safety in heavy-duty industrial applications. This integrated system combines a hydraulic lock (piloted check valve), a balance valve (overcenter valve), and a solenoid-operated directional valve to ensure precise and safe control of hydraulic cylinders and motors, particularly in crane, construction, and material handling equipment.

Key Features

Dual-Function Design: Integrates a hydraulic lock for leak-free load holding and a balance valve to prevent uncontrolled descent under gravity or overload conditions, ensuring stability and safety.
Solenoid Actuation: Features an electrically controlled solenoid valve for remote operation, enabling automated or manual override of hydraulic functions with minimal effort.
Lock Nut Mechanism: Includes a robust lock nut design to secure valve adjustments and maintain preset pressure settings, preventing unintended loosening due to vibration or pressure fluctuations.
High-Pressure Resilience: Engineered for demanding environments with pressure ratings up to 350 bar (35 MPa), suitable for heavy-load crane and cylinder applications.
Leak-Resistant Construction: Utilizes precision-machined components and hardened seals (e.g., Viton® or Polyurethane) to minimize internal leakage and extend service life.
Adjustable Control: Allows fine-tuning of cracking pressure and flow rates to match specific system requirements, optimizing performance for varying load conditions.

Technical Specifications

Pressure Range: Up to 350 bar (35 MPa)
Flow Capacity: 30–120 L/min (model-dependent)
Solenoid Voltage: DC 12V/24V or AC 110V/220V options
Mounting: ISO 4401 or CETOP modular mounting patterns
Materials: Carbon steel body, hardened steel valve core, corrosion-resistant coatings

Applications

Crane Hydraulic Systems: Load holding and boom control in mobile and stationary cranes.
Industrial Cylinders: Precision motion control for press brakes, injection molding machines, and metallurgical equipment.
Mobile Machinery: Stabilizing legs, winches, and lifting mechanisms in construction and agricultural equipment.
Safety-Critical Systems: Emergency braking and overload protection in material handling and automation systems.

Advantages

Enhanced Safety: Prevents accidental cylinder drift or load drops through positive mechanical locking and balanced pressure relief.
Energy Efficiency: Reduces hydraulic power consumption by maintaining load position without continuous pump operation.
Low Maintenance: Self-compensating seal design and easily accessible adjustment points simplify upkeep.
Customization: Available in multiple configurations (e.g., port sizes, solenoid types, pressure settings) to meet OEM requirements.
