Sun Cartridge Valve NQEB-XAN Floating Design Quick Start Automatic Reopening

Product Specification

Description:

The Sun Cartridge Valve NQEB-XAN is an air bleed and priming cartridge valve manufactured by Sun Hydraulics. Its primary function is to evacuate trapped air from the hydraulic system during startup, thereby reducing startup power requirements and facilitating pump priming. This Series 2 valve is suitable for T-3A cavities, has a flow range of 4 to 50 gallons per minute (GPM), and a maximum operating pressure of 5000 psi. The valve features a floating design, which effectively reduces the possibility of internal parts seizing due to excessive installation torque or cavity/cartridge machining errors. It also features a 150-micron stainless steel filter to protect the mainstage orifice and extend product life.
 

Applications:

Industrial Hydraulic Systems: The NQEB-XAN is widely used in various industrial hydraulic systems, such as injection molding machines, hydraulic presses, and hydraulic presses. In these equipment, air is often trapped in the hydraulic system during startup, increasing startup power requirements and potentially damaging the hydraulic pump. The NQEB-XAN effectively resolves these issues by purging air from the system, ensuring smooth and efficient startup of the hydraulic system.
Construction Machinery: Hydraulic systems in construction machinery such as excavators, loaders, and cranes require frequent starting and stopping. The NQEB-XAN's fast response and efficient air purging capabilities ensure rapid air purging during startup, reducing hydraulic shock and improving equipment reliability and service life.
Metallurgy and Heavy Machinery: Hydraulic systems in the metallurgical and heavy machinery sectors often operate at high pressure and flow rates. The NQEB-XAN's high pressure resistance and high flow capacity make it an ideal choice for these applications. It effectively reduces air entrapment during startup, lowers the hydraulic system's power requirements, and improves overall system efficiency.
Testing and Simulation Equipment: In systems requiring high dynamic response, such as hydraulic test benches, flight simulators, and automotive test equipment, the NQEB-XAN provides high-frequency, high-precision hydraulic control to meet complex testing requirements.

Advantages:

Floating Design: The NQEB-XAN utilizes a floating design, allowing its closely fitting working components to float within the valve body, reducing sensitivity to installation torque and preventing the possibility of internal moving parts seizing.
Durable Design: The valve body and internal components are heat-treated for excellent wear, impact, and fatigue resistance, ensuring a long service life.
Protective Device: The main-stage orifice is protected by a 150-micron stainless steel filter, effectively preventing contaminants from entering and extending product life.
Quick Start: When the hydraulic system is started, the NQEB-XAN quickly purges air from the system, reducing power requirements during startup and facilitating rapid pump priming.
Automatic Reopening: When system pressure drops below 25 psi (1.7 bar), the valve automatically reopens, ensuring there is no trapped air in the system.
High Installation Torque: The floating design allows for higher installation torque, ensuring a secure installation and preventing loosening or oil leaks.
Easy Maintenance: Cleaning or inspecting the cartridge valve does not require changing the existing valve settings or disassembling piping. Multiple Configuration Options: The NQEB-XAN offers a variety of configuration options to meet diverse user needs.
Wide Applicability: Suitable for a variety of hydraulic systems, including open and closed circuits.
