  • Selection of Valves and Their Appropriate Locations

  • What are the types of air vent valves?

  • Where the Ball Valve is used.

    Because the ball valve usually uses rubber, nylon and polytetrafluoroethylene as the seat sealing ring material, its use temperature is limited by the seat sealing ring material.

  • What kind of quick cut-off ball valve?

    Ball valve is a common pipeline control device that can be used to cut off, open, or regulate the flow of fluid in pipelines. Quick cut-off ball valve is a special type of ball valve, which is characterized by faster cut-off speed and higher tightness performance than ordinary ball valves. It can achieve complete isolation of fluids in an instant to protect the safe operation of pipeline systems.

  • What are the characteristics of ball valves?

    Pneumatic ball valves have a simple and compact structure, reliable sealing, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. They are suitable for general working media such as water, solvents, acids, and natural gas. They are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control.

  • Why are pneumatic valves more commonly used than electric valves for important valves?

    neumatic valves have inherent safety features. In complex working environments, there are many electrical devices and potential sources of electrical interference. Electric valves rely on electric power for operation, and when electrical faults occur—such as short circuits, leakage, overloads, or electromagnetic interference—there is a high risk of malfunction in their control systems. For example, near areas with strong electromagnetic radiation, electric valves might receive incorrect signals, causing them to open or close unexpectedly, which can pose significant safety hazards to the entire system's operation.
