HAWE BVG Series Seated Valve | BVG 3 R-G 24-PYD | BVG 1 R-XM 24

The BVG Series directional seated valves manufactured by Chengyuan Hydraulic are high-performance, 100% interchangeable alternatives designed to meet the rigorous German HAWE standards. Unlike traditional spool valves, the BVG series utilizes a poppet/seated design. The primary engineering advantage lies in its metal-to-metal seal, which ensures zero-leakage performance in hydraulic circuits. It is the premier choice for hydraulic cranes, attachment locking, and pressure-holding loops. For specific codes such as BVG 3 R-G 24-PYD and BVG 1 R-XM 24, we employ precision lapping processes for the valve cores. Every unit undergoes 100% simulated load testing at 400 bar to guarantee robust performance in demanding mobile and industrial applications.

Key Technical Advantages:

• Absolute Zero-Leakage: The precision-lapped ball-seat interface eliminates microscopic internal leakage under high pressure. This prevents actuator drift in boom cylinders, ensuring maximum operational safety.

• High Pressure Rating (400 bar): The all-steel forged body is surface-hardened to withstand 400 bar continuous pressure, far exceeding the limits of standard industrial spool valves.

• High-Response Solenoid Control: The wet-pin solenoid assembly is optimized for rapid switching and excellent heat dissipation, meeting the precision requirements of crane micro-movements.

• Modular Interchangeability: Fully compliant with HAWE BVG mounting patterns and electrical interfaces. No modification to the existing manifold or wiring is required, allowing for a “plug-and-play” replacement.

Application Areas:

• Cranes & Lifting: Boom extension locking, outrigger pressure holding, and load-holding control.

• Mobile Machinery: Attachment control for tractors and hydraulic distribution in harvesters.

• Machine Tools: Hydraulic chuck clamping and safety cut-off circuits for stamping presses.

Expert Maintenance Tips:

• Installation Check: As a manifold-mounted valve, ensure the mounting surface is flat and burr-free. Verify that the O-rings are correctly seated and undamaged to prevent external leaks.

• Voltage Stability: For G 24 or XM 24 solenoids, ensure the 24V DC power supply fluctuates within $\pm 10\%$. Over-voltage causes coil overheating, while under-voltage may prevent full spool actuation.

• Contamination Control: Seated valves are sensitive to particulates. A single particle trapped in the seat can cause leakage. We recommend 10-micron high-precision filtration at the pressure inlet.
