Pipeline transportation has become the primary mode of energy transport in modern times, and the resulting development of pipeline valves has been rapid, greatly promoting the progress of pipeline transportation. How exactly are pipeline valves defined, and what are the differences in their structure, characteristics, and performance? Today, let’s take a closer look at the […]
Liu Zhi (TEJI VALVE GROUP CO.,LTD. , Wenzhou 32500) Abstract: This paper introduces an ultra-low temperature valve test device. The test device has the dual functions of low-temperature test liquid medium recovery and helium gas pressurization recovery for leak detection, so that the test liquid medium and gas medium can be recycled, energy saving and […]
Recently, TEJI Valves Group obtained two invention patent authorizations: “Online Maintenance Cryogenic High-Performance Ball Valve (Authorization Announcement No.: CN 113236810 B)” and “Compact Online Maintenance Cryogenic Butterfly Valve (Authorization Announcement No.: CN 113154056 B),” marking another significant breakthrough in our extreme operating condition valve technology. The patent “Online Maintenance Cryogenic High-Performance Ball Valve” is a […]
A plug valve is a shut-off component—it opens and closes by rotating the valve disc 90 degrees around the valve body’s centerline, used to cut off, distribute, and change the flow direction of media in pipelines. The working principle of a plug valve is to regulate and cut off fluid flow by rotating the valve disc to […]
Installation of a Flanged Ball Valve Preparation Before Ball Valve Installation The upstream and downstream pipelines should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to withstand the weight of the ball valve; otherwise, appropriate supports must be provided on the pipeline. Clean the pipelines […]
Gate Valve Definition and Terminology Gate Valve Definition: A gate valve is a valve that opens and closes by moving its gate perpendicular to the direction of media flow (channel axis). Among various types of valves, the gate valve is the most widely used. Gate valves are mainly used in pipelines to cut off the […]
