Burkert Type 6481 2/2-Way Piston Valve for Pressure Control Applications up to 450 Bar

The Burkert Type 6481 is a high-performance 2/2-way piston valve professionally designed for precise industrial pressure control, supporting stable operating pressures up to 450 bar. Tailored for medium-to-high pressure process conditions, it provides reliable, leak-tight on/off control for gases and liquids, serving as a versatile solution for general high-pressure industrial systems.

• Piston system with mechanical seal bearings
• Explosion-proof variant ATEX and IECEx available
• Inspection holes for monitoring the process seal
• Certified 3.1 materials suitable for hydrogen applications
• Carbon-coated magnetic steels for enhanced durability
• Push-over coil available as Zone 1 or Category 2 explosion-proof variant

Adopting a mature servo-assisted piston operating principle, the valve features sensitive switching and excellent pressure resistance. It requires low differential pressure for smooth actuation, ensuring steady and repeatable operation during frequent cyclic work. Built with high-strength alloy materials and premium durable seals, it delivers exceptional structural rigidity and anti-leakage performance under long-term high-pressure loads.

Compact in structure and easy to install, the Type 6481 features strong environmental adaptability and low maintenance demands. It is widely applied in hydraulic systems, industrial pressure regulation, process fluid control and medium-pressure gas handling equipment. Balancing outstanding durability, stable pressure resistance and cost efficiency, this valve is a dependable core component for standardized high-pressure fluid control applications across diverse industrial automation scenarios.
