Today, when listening to the class, the teacher asked what kind of electric ball valve should be used if there is a horizontal compensation amount and a vertical compensation amount. He was thinking, this must not be the common type of electric ball valve, which should be the big rod electric ball valve. He answered the teacher's question, the answer is no, the correct answer is the double small rod electric ball valve, There are horizontal compensation amount and vertical compensation amount. Sometimes when a mistake is made, the correct answer will be kept in mind. What is the difference between internal pressure electric ball valve and external pressure electric ball valve.
There are generally two types of electric ball valves used in heating pipelines: internal pressure type and external pressure type. The internal pressure type is the medium inside the electric ball valve, the external pressure type is the medium outside the electric ball valve, the internal pressure type is the electric ball valve based on the compression absorption pipeline, and the external pressure type is the electric ball valve based on the tension absorption.
