Advancing Vertical Logistics: Ningbo Longerfa Unveils Next-Generation Hydraulic Control Valve Groups for Lifting Cargo Elevators

Redefining Hydraulic Performance for Modern Cargo Lifts

Hydraulic cargo elevators rely on the seamless coordination of multiple subsystems to ensure smooth, safe, and efficient operation. At the heart of these systems lies the hydraulic control valve group—a critical component that regulates the flow, pressure, and direction of hydraulic fluid to manage the lifting and lowering of the elevator platform.

Recognizing the industry’s evolving requirements, Ningbo Longerfa’s engineering team has developed an advanced line of modular Hydraulic Valve groups that integrate core functionalities such as:

• Load-holding safety valves

• Speed control flow valves

• Pressure Relief and balance valves

• Electromagnetic directional Control Valves

• Integrated check and throttle valves

This integrated approach minimizes external piping, reduces leakage risk, and simplifies installation—offering a compact yet robust solution ideal for high-frequency industrial lifting applications.

Designed for Industrial Reliability

“At Longerfa, we believe in building components that not only meet current market standards but exceed them,” said Mr. Wang Yu, Chief Product Engineer at Ningbo Longerfa. “Our new valve groups are designed to operate under demanding industrial conditions with high loads, frequent cycles, and varying temperatures.”

Engineered using high-strength alloy steel and precision CNC machining, the new valve groups undergo strict quality control, including:

• 100% pressure and leakage testing before delivery

• High-cycle endurance testing (over 1 million cycles)

• Salt spray corrosion resistance tests exceeding 400 hours

• Certified compliance with ISO 4413, CE, and RoHS standards

The result is a product that delivers outstanding durability and stable performance—ideal for vertical transportation in factories, logistics hubs, airports, and heavy storage facilities.

Smart Control for Enhanced Safety

One of the highlights of Longerfa’s valve group design is its fail-safe hydraulic logic, which prioritizes operational safety at all times. Whether in lifting, holding, or lowering modes, the valves ensure:

• Smooth deceleration to avoid load shock

• Load-holding even in case of sudden power failure

• Precision speed control with anti-cavitation design

• Integrated manual override for emergency operations

Incorporating proportional valve options and electronic feedback modules, the control valve groups can be easily connected to modern PLC or IoT control systems, allowing for remote monitoring, predictive maintenance, and integration into smart factory environments.

Applications Across Diverse Industries

The flexibility and reliability of Longerfa’s hydraulic valve groups make them suitable for a wide range of cargo lifting applications, including:

• Warehouse and pallet elevators

• Freight elevators in industrial plants

• Loading platforms and dock lifts

• Mining and underground logistics lifts

• Vehicle-mounted lifting systems

Thanks to a modular design philosophy, Longerfa offers custom valve configurations based on the load capacity, lifting height, and operational requirements of each customer’s application.

Green Hydraulics: Efficiency Meets Sustainability

With rising energy costs and growing environmental awareness, hydraulic systems are increasingly being judged by their energy consumption and environmental impact. Longerfa’s new valve groups feature low-internal-leakage designs, energy-saving descent control, and optimized flow pathways to reduce energy usage and heat generation.

Additionally, the use of biodegradable hydraulic fluids is fully supported, contributing to greener industrial operations and compliance with stricter environmental regulations.

Customer-Centric Customization and Support

Understanding that each lifting application has unique parameters, Ningbo Longerfa offers full-service customization options including:

• Flow and pressure tuning

• Port threading customization (BSP, NPT, SAE, Metric)

• Mounting design adaptations

• Optional integration of pressure sensors or solenoids

• OEM/ODM branding and labeling services

From initial consultation to final delivery, Longerfa’s technical support team ensures every customer receives a tailored solution that aligns with their operational needs and budget.
