Hydraulic Cartridge Valve VBCD-M18-L.5-DE-FL Hydraulic Control Valve Solenoid Operated

Product Introduction

The VBCD-M18-L.5-DE-FL is a compact, high-performance hydraulic cartridge valve designed for precise flow control. It features a direct-acting, poppet-type check valve configuration with a free-flow direction and controlled reverse flow. The model name indicates its key specifications: a cartridge style with "B" size cavity (ISO 7368), a 1.8 mm nominal pilot orifice. The "DE" suffix denotes a two-port (dual) design with an elastomer seal, suitable for manifold mounting. Its robust construction from hardened steel ensures high pressure capability and excellent resistance to contamination. This valve is known for its low leakage, fast response, and reliable operation in demanding hydraulic systems, making it a core component for creating custom hydraulic circuits in integrated blocks.

Product Summary

Hydraulic valves are crucial components in fluid power systems, directing and regulating the flow of hydraulic fluid to control the force, speed, and direction of actuators. The main categories are:

1.  **Directional Control Valves:** Manage flow paths (e.g., spool, poppet, check valves).
2.  **Pressure Control Valves:** Limit system pressure for safety and control (e.g., relief, reducing, sequence valves).
3.  **Flow Control Valves:** Regulate actuator speed by adjusting flow rate (e.g., throttle, flow dividers).

They operate via mechanical, solenoid, or proportional/electro-hydraulic actuation. Constructed from high-strength materials like steel, they are designed to withstand extreme pressures, shock, and contamination. Selecting the correct valve is essential for system efficiency, safety, and precise control in mobile equipment, industrial machinery, and manufacturing automation.

Product Application

The VBCD-M18-L.5-DE-FL is primarily used as a pilot-operated check valve or a core element in more complex hydraulic control functions. Its main application is to securely hold loads by blocking reverse flow in cylinders or motors until a pilot pressure signal allows controlled release. This makes it essential in safety-critical systems. Common uses include locking hydraulic cylinders in material handling equipment (like lifts and loaders), securing actuators in industrial automation and presses to prevent unintended movement, and providing load-holding in mobile machinery such as crane outriggers or boom sections. Its compact size and reliable performance also make it suitable for use in compact valve manifolds for machine tools and plastic injection molding machines, where precise motion control and safety are paramount.
