Vanaz V-4327 Slam Shut Valve Flanged – Industrial Emergency Gas Isolation System

The Vanaz V-4327 Slam Shut Valve Flanged is an advanced safety component used in gas pressure regulating stations for LPG, Natural Gas, and other non-corrosive gases.

It is installed immediately after the filter and before the regulator, where it continuously monitors downstream pressure through an impulse line. In normal conditions, the valve remains open and allows uninterrupted gas flow. When pressure exceeds the preset safe limit, it instantly shuts off the downstream supply to prevent system damage or hazardous situations.
