Hawe BVG Series Solenoid Directional Valve | BVG 1 BVG 2 | Leak-Free Poppet Valve

The BVG Series Solenoid Directional Poppet Valves by Chengyuan Hydraulic are engineered for high-pressure applications where absolute sealing integrity is paramount. Fully interchangeable with Hawe BVG 1 and BVG 2 series, our valves feature a precision-engineered poppet design that ensures zero-leakage in the closed position. Unlike standard spool valves, the BVG series eliminates internal bypass, making it the premier choice for load-holding and clamping circuits. Every valve undergoes 100% simulated condition testing to guarantee reliable switching performance at pressures up to 400 bar.

Technical Specifications :

Key Technical Advantages:

• Leak-Free Poppet Technology: The valve core and seat are crafted from hardened steel and precision-lapped. This metal-to-metal seal provides superior shut-off performance, preventing any drift in hydraulic cylinders during long clamping cycles.

• High-Pressure Reliability: Designed to handle 400 bar continuous pressure. The solenoid force is optimized to overcome static friction, ensuring crisp and rapid switching even after long periods of inactivity.

• All-Steel Construction: Unlike cast-iron or aluminum alternatives, our all-steel body offers maximum structural rigidity, eliminating risks of fatigue-related body expansion or external leaks under pressure spikes.

• Heavy-Duty Solenoids: Equipped with high-performance coils that offer excellent thermal dissipation and vibration resistance, ensuring a long service life in harsh industrial or mobile environments.

Application Areas:

• Machine Tools: Clamping systems and spindle locking mechanisms.

• Clamping Units: Hydraulic jigs requiring sustained pressure without power consumption.

• Mobile Hydraulics: Outrigger locking and auxiliary control for compact machinery.

Expert Maintenance Tips:

• Fluid Filtration: Poppet valves are sensitive to particulates. Maintain a filtration level of ISO 4406 18/15/12 to protect the precision-lapped seats from erosion or sticking.

• Mounting Torque: Always use a torque wrench for installation to avoid body distortion. Recommended torque for BVG 1 is 9.5 Nm; for BVG 2 is 20 Nm.

• Solenoid Care: Ensure the power supply is stable within ±10% of the rated voltage to prevent coil burnout or inconsistent switching.
