Vanaz V-4330 Slam Shut Valve Flanged – Advanced Industrial Gas Safety Isolation System

The Vanaz V-4330 Slam Shut Valve Flanged is a precision-engineered safety device used in LPG and Natural Gas pressure regulating systems to prevent dangerous overpressure conditions.

Installed immediately after the gas filter and before the regulator, it continuously monitors downstream pressure through an impulse sensing line. Under normal conditions, the valve remains open, allowing uninterrupted gas flow. When pressure exceeds the preset safety limit, it instantly shuts off the gas supply to protect pipelines, regulators, and downstream equipment.
