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...

The sealing damage of the steam trap valve is the main cause of internal leakage of the valve. There are many reasons for valve sealing failure, among which the failure of the sealing pair composed of the valve core and valve seat is the main reason. There are many reasons that affect the damage of the valve sealing surface, including mechanical wear caused by incorrect selection, high-speed erosi...

In industrial valve systems, strainers are essential components for ensuring smooth fluid flow and protecting downstream equipment. However, when an oil strainer becomes clogged, it can lead to a series of issues, significantly impacting the system's stability and safety. Common Causes of Oil Strainer Blockage (1) Excessive Impurities The working medium contains a large amount of particulat...

1. What Is a Valve Welding Electrode? A valve welding electrode refers to a category of welding consumables specifically used for hardfacing, repair welding, and overlay welding of valve components, including the valve body, sealing surfaces (such as valve seats and valve discs), as well as welding joints between valves and pipelines. It is not a single product, but rather a general ...

Introduction: Why Steam Isolation Demands Specialized Valves High-temperature steam systems are the backbone of many industrial processes—from power generation to chemical processing and refinery operations. When it comes to pipeline isolation for maintenance or safety, the choice of valve can mean the difference between a routine shutdown and a catastrophic failure. Line blind v...

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...
