Vanaz V-4325 I Slam Shut Valve – Industrial Gas Emergency Shut-Off Protection

The Vanaz V-4325 I Slam Shut Valve is a high-performance safety device used in LPG and Natural Gas pressure regulating systems.

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

During normal operation, the valve remains open and allows uninterrupted gas flow. If the outlet pressure exceeds the preset safety limit, the valve responds instantly and shuts off the gas supply to protect the entire system.

Product Highlights

Instant Automatic Shut-Off

Rapidly closes gas flow when unsafe pressure conditions are detected.

Installed Between Filter and Regulator

Ensures accurate pressure monitoring and system protection.

Impulse Line Sensing System

Detects pressure variations and triggers immediate shutdown.

Manual Reset Operation

Requires manual reopening after system correction and maintenance.

Heavy-Duty Industrial Construction

Designed for long service life in demanding gas applications.
