Custom Hydraulic Lock Valve

Key Features & Customization Capabilities

1.Core Function: Reliable Load Holding:The valve operates as a pilot-operated check valve, allowing free flow in one direction while sealing off the reverse flow until a pilot signal is applied. This creates a positive, leak-tight lock that holds hydraulic cylinders in position, preventing unintended movement due to load pressure or system leakage. We offer both single and dual pilot check valve configurations for single-acting and double-acting cylinder applications.

2.Full Customization Support:We provide one-stop customization services to match your specific requirements:

• 2-1 Pressure & Flow: Custom pressure ratings (up to 350 bar or higher) and flow capacities to suit your system’s needs.

• 2-2 Port & Manifold Design: Custom port sizes, thread types (BSPP, NPT, metric), and manifold mounting configurations for direct integration into your hydraulic circuits.

• 2-3 Materials & Treatments: High-strength carbon steel, alloy steel, or stainless steel construction, with optional phosphating, black oxide, or plating for enhanced corrosion resistance.

• 2-4 Mounting Styles: Available as cartridge-style valves for manifold blocks or line-mounted valves for direct piping connections.

  3.High Precision & Leak-Proof Performance:Manufactured with advanced CNC machining, our hydraulic lock valves feature precision-matched spool and seat components, ensuring minimal internal leakage. Each valve undergoes rigorous pressure testing, leakage testing, and functional testing to guarantee reliable performance under continuous use, shock loads, and temperature variations.

  4.Wide Range of ApplicationsOur custom hydraulic lock valves are widely used in applications requiring precise load holding, including:

• Mobile machinery (cranes, forklifts, aerial work platforms)

• Construction equipment (excavators, boom lifts)

• Industrial automation presses and lifting equipment

• Hydraulic power units and cylinder control systems

• Any application where preventing load drift is critical for safety and performance.
