In today's valve family, gate valve is relatively widely used. Among them, wedge type double gate valve and wedge type elastic gate valve are the most widely used, because they have the best sealing effect. Everything has its advantages and disadvantages. It is because of its good sealing effect that the pressure in the middle chamber will rise abnormally in some occasions. Abnormal boost pressure...

Difference A safety valve is a special valve in which the opening and closing parts are in a normally closed state under external force. When the pressure of the medium in the equipment or pipeline increases beyond the specified value, the medium is discharged outside the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves bel...

Selecting a plug valve for high-pressure service is rarely just about matching the pressure class on a datasheet. In actual industrial systems, valve performance is influenced by temperature, media condition, operating frequency, sealing design, and maintenance accessibility. A plug valve that performs well in clean liquid service may fail much faster in steam, slurry, or corrosive chemical applic...
