JIS Standard Steel Globe Valve Specifications and Applications for Industrial Use

Understanding JIS Steel Globe Valves A Comprehensive Guide

Globe valves play a critical role in fluid control systems across various industries, and JIS (Japanese Industrial Standards) steel globe valves are particularly notable for their reliability and efficiency. These valves are designed to regulate the flow of liquids and gases through a pipeline, making them vital components in diverse applications ranging from water treatment plants to petrochemical facilities. In this article, we will explore the characteristics, benefits, applications, and maintenance of JIS steel globe valves.

What is a Globe Valve?

A globe valve is a type of valve that uses a spherical body and a movable disk-type element to control fluid flow. The design features a linear motion, allowing for precise control over the flow rate, making it suitable for throttling applications. The globe valve is characterized by its distinctive shape, which resembles a globe or sphere, hence the name.

JIS Standards
