Description:

The Sun Hydraulic Valve CWIG-LGN is a high-performance, cartridge-type counterbalance valve manufactured by Sun Hydraulics, primarily used for controlling overrunning loads. This valve allows free, one-way flow of hydraulic oil from the directional valve (port 2) to the load port (port 1). It also functions as a direct-acting, pilot-assisted relief valve, controlling reverse flow from port 1 to port 2. Its design features include pilot-assisted

opening and an external bleed port, effectively controlling load movement.

Applications:

Construction Machinery: The CWIG-LGN is widely used in the hydraulic systems of construction machinery such as excavators, cranes, and loaders. It effectively controls the load on hydraulic cylinders or hydraulic motors, ensuring stability and safety under complex operating conditions.
Industrial Machinery: In industrial machinery such as injection molding machines, hydraulic presses, and hydraulic presses, the CWIG-LGN can be used to control the movement of hydraulic cylinders, ensuring precise operation. For example, during the mold opening and closing process of an injection molding machine, the valve precisely controls the speed and direction of the hydraulic cylinder, improving production efficiency and product quality.
Aerospace: In the aerospace sector, hydraulic systems require extremely high precision and reliability. Due to its high performance and reliability, the CWIG-LGN is widely used in aircraft landing gear retraction and extension systems, flight control surface actuation systems, and other applications.
Marine and Offshore Engineering: Ship hydraulic systems, such as steering gear, cranes, and anchor winches, must operate reliably in harsh marine environments. The corrosion resistance and high reliability of the CWIG-LGN make it an ideal choice for ship hydraulic systems.
Oilfield and Mining Machinery: Hydraulic equipment in oilfield and mining machinery must operate under high loads and harsh environments. The CWIG-LGN's high load capacity and pollution resistance enable it to meet the demands of these demanding conditions.

Advantages:

Pilot-Assisted Opening: The CWIG-LGN utilizes a pilot-assisted opening design, enabling fast response and high flow control at low pressures. This design not only improves system response speed but also reduces energy consumption.
Drain Port: The valve features a drain port, which effectively reduces the impact of backpressure on valve performance, improving system stability and reliability. High Load Capacity: The CWIG-LGN can withstand high loads and is suitable for applications requiring high torque and pressure.
Floating Construction: Sun Hydraulics' floating cartridge valve construction is a significant advantage. The free-floating design at the valve tail allows the closely fitting working components to float within the valve body, reducing installation torque sensitivity and preventing the possibility of seizure of internal moving parts.
Durable Materials: The valve is constructed of high-quality carbon steel and heat-treated for excellent wear, impact, and fatigue resistance, ensuring a long service life.
Precision Manufacturing: Sun Hydraulics is renowned for its precision manufacturing processes and stringent quality control. Every component of the CWIG-LGN is precisely machined and rigorously tested to ensure high performance and reliability under various operating conditions.
Compact Design: The CWIG-LGN's compact design, small size, and lightweight make it easy to integrate into existing hydraulic systems.
Multiple Mounting Options: The valve offers a variety of mounting options, including direct mounting in the actuator housing, increasing system flexibility and protection. Easy Maintenance: The CWIG-LGN's simple design allows for easy maintenance. Its floating structure reduces wear on internal components and lowers maintenance costs.
Low Pressure Loss: The CWIG-LGN's design optimizes the hydraulic oil flow path, reducing pressure loss and improving overall system efficiency.
Precise Control: By precisely controlling the flow and direction of hydraulic oil, the valve avoids unnecessary energy waste and achieves energy-efficient operation.
