Cast steel gate valve-Yuming Valve

INTRODUCTION

The Z41H national standard cast steel gate valve is a gate valve with flange connection, which is a common connection method. Cast steel gate valves are stable and reliable when used in pipelines, so flange gate valves are used in high-pressure pipelines. They are widely used in metallurgy, mining, building materials, food, chemicals and other industries to control flow changes or quickly cut off.
