Globe valves are essential control devices in fluid transmission systems, primarily designed to regulate or shut off flow through the linear motion of their disc. While installing a globe valve in reverse might not seem to directly impact water flow at first glance, incorrect installation can significantly affect valve performance, lifespan, and system safety due to its internal structural design and working principles. This article provides an in-depth analysis of the importance of globe valve...
In the design and application of ball valves, O-rings play a critical role as essential sealing components. The sealing performance of the O-ring directly affects the ball valve's operational efficiency and lifespan. When selecting the material and hardness of O-rings, it is important to consider the valve's working environment, the type of medium, and the temperature and pressure requirements. Common O-ring materials include fluorocarbon rubber (FKM), nitrile rubber (NBR), silicone rubber...

The bellows sealed globe valve, a modern variant of the traditional globe valve, utilizes a unique bellows sealing design. This design, with its dual sealing structure comprising both the bellows and packing, offers superior sealing performance compared to conventional globe valves. Bellows sealed globe valves are widely used in applications where high sealing reliability is critical, particularly in high-pressure, high-temperature environments like petrochemical, chemical, and steam systems. However,...
герметичностьindustrial valveTypes of Valve Sealing Performance To address this issue, low-temperature valve designs typically avoid using traditional non-metallic sealing materials, especially in environments where temperatures fall below -70°C. Non-metallic materials can be combined with metals through special processes to form composite structures to improve low-temperature sealing performance. However, some non-metallic materials still perform well at low temperatures. For example, polyethylene...
In industrial control systems, quick shut-off ball valves play a critical role as key safety components. Their primary function is to rapidly shut off fluid flow in emergency situations, ensuring the safe operation of the system. In high-risk industries such as high-pressure gas, coal chemical processing, and petrochemical sectors, these valves are essential for quickly cutting off flammable, explosive, or toxic substances, preventing the escalation of accidents and further harm. Due to their simple...
