Introduction

A valve designed to safely control LNG, liquid oxygen, and similar media in cryogenic environments below -196°C.

Its extended bonnet structure prevents external heat ingress, protecting the stem from freezing, while offering high sealing performance and low pressure loss through quick 90-degree quarter-turn operation.
