VNN 810 (spring loaded)

Description:

The VNN 810 is a spring-loaded relief valve engineered to safely vent excess pressure from gas systems. Designed for continuous or intermittent overpressure events, it opens precisely at a preset value and reseats reliably once normal pressure is restored. With rugged construction and low hysteresis, the VNN 810 is ideal for protecting pipelines, pressure regulators, and storage tanks in both industrial and utility gas applications.

Features:

• Set pressure adjustable up to 10 bar
• Spring-loaded design with precise response and fast reseating
• Available in sizes DN 25 to DN 100
• Compact and space-saving inline body
• Optimized for natural gas
• Operates in both continuous and emergency relief scenarios
• Stable performance with minimal blowdown and low hysteresis
• Flanged or threaded connection options (DIN/ANSI standards)
