Valve subassembly

Valve assemblies are an important industrial piece of equipment used to control the flow, pressure, and direction of fluids. It is composed of valve body, valve cover, valve stem, valve disc and other parts. The valve assembly has the function of opening and closing the fluid channel, adjusting the flow and pressure of the fluid according to the process requirements to ensure the normal operation of the system. Valve components are widely used in petroleum, chemical, electric power, metallurgy, water treatment and other industries.

The valve assembly works by controlling the passage of the fluid by opening and closing the disc. When the valve is closed, the valve disc fits snugly with the valve seat to prevent fluid from passing through; And when the valve opens, the disc separates from the valve seat, allowing fluid to pass through. The operation of the valve assembly can be carried out manually, electrically or pneumatically to meet the requirements of different operating conditions.

The valve assembly has the characteristics of simple structure, reliable operation and good sealing. It can select different materials and types of valves according to the nature of the fluid and process requirements, such as globe valves, regulating valves, check valves, etc. At the same time, the valve assembly can also be customized according to the special requirements of the use environment to improve the performance and reliability of the equipment.

In short, valve assemblies are indispensable and important equipment in modern industrial production, and they play an important role in controlling fluid transfer and processes.
