Available in various versions — RegO 3127, 3127G, 3127H and 3127J — easily adapts to different operating conditions and applications, ensuring consistent performance and long durability.
Installation is simple, via 1/4″ M.NPT thread, ensuring secure sealing and complete leak-tightness. Ideal for use in gas tanks, distribution systems, reservoirs and other industrial applications where safety is essential.
When pressure reaches the limit, the valve opens automatically to relieve excess pressure.
How it works:
Its “Pop-Action” design allows for a fast and controlled response, minimizing gas loss during relief. After discharge, the valve reseats automatically, ensuring a firm and tight seal.
The resilient sealing disc ensures bubble-tight sealing, preventing leaks and ensuring maximum system safety.
