What are the characteristics of a coaxial valve?

Apr 28,2025

A coaxial valve is a common type of valve with the following characteristics:

Compact Structure Coaxial valves use a coaxial design for the valve stem and seat, resulting in a more compact structure with small size and light weight. This makes them easy to install and maintain, especially suitable for space-constrained applications.
Good Sealing The sealing surface design between the valve stem and seat is reasonable, usually using metal or non-metal seals, achieving good sealing performance and effectively preventing media leakage. It is suitable for systems with high sealing requirements.
Good Flow Characteristics Coaxial valves have relatively unobstructed flow paths, resulting in low fluid flow resistance. This allows for a larger flow coefficient, enabling higher flow rates with the same diameter, improving system efficiency.
Fast Response Speed Because the valve stem has a short stroke and relatively low driving force, coaxial valves can quickly respond to control system commands, achieving rapid shutoff or adjustment of fluid flow. They are suitable for applications requiring quick action.
High Adjustment Accuracy Through the precisely designed valve stem and seat structure, and a suitable actuator, coaxial valves can achieve precise flow regulation to meet the flow control accuracy requirements of different operating conditions.
Wide Operating Pressure Range Coaxial valves can be designed for different pressure levels according to different application requirements, operating stably from low to high pressure.
Strong Corrosion Resistance Different materials can be selected to manufacture coaxial valves according to the properties of the medium, such as stainless steel, alloy steel, and plastics, giving them good corrosion resistance and making them suitable for various corrosive media piping systems.
