Vanaz V-4328 Slam Shut Valve Flanged – Industrial Gas Safety Isolation System

The Vanaz V-4328 Slam Shut Valve Flanged is a robust and precision-engineered safety component used in LPG and Natural Gas pressure regulating systems.

It is installed immediately after the gas filter and before the regulator, where it continuously monitors downstream pressure through an impulse sensing line.

Under normal conditions, the valve remains open to allow uninterrupted gas flow. However, when the downstream pressure exceeds the preset safety limit, the valve activates instantly and shuts off the gas supply to protect the system from hazardous overpressure situations.
