VNN 820 (pilot operated)

Description:

The VNN 820 is a pilot-operated safety relief valve engineered for high-capacity pressure relief in demanding gas applications. Unlike traditional spring-loaded valves, its pilot system ensures stable operation, higher flow efficiency, and precise opening and closing pressures. Designed for applications requiring tight sealing, minimal product loss, and quick reseating, the VNN 820 is ideal for pipelines, storage tanks, and processing systems across energy and industrial sectors.

Features:

• Pilot-operated mechanism for high precision and reduced blowdown
• Handles gas under varying operating conditions
• Tight shutoff minimizes leakage and product loss
• Excellent flow capacity with lower inlet pressure loss compared to spring valves
• Set pressure range from 1 bar to 80 bar depending on model
• Full lift and modulating options available
• Backpressure compensation via pilot control system
• Available in DN25 to DN100 sizes
