✅ Product Introduction

The Fisher Type VS100 Slam-Shut Valve is a critical safety protection device designed for gas pressure systems that require instant shut-off during abnormal pressure conditions.

When inlet or outlet pressure exceeds the preset limit, the VS100 automatically triggers a mechanical shutoff, immediately stopping gas flow and preventing equipment damage, leakage risks, and safety incidents.

Available in medium-capacity and high-capacity configurations, with multiple orifice and connection options, this valve provides flexible installation and stable performance across different pipeline systems.

It is not only a control component — it is a last-line safety shield for your gas network.
