4 inch Ball Valve
A 4 inch ball valve is a crucial component in many pipeline systems. With a nominal diameter of DN100, it’s designed to handle relatively large-scale fluid flow. Its main function is to control the on, off and regulation of the flow.
This type of valve is popular for its simple yet robust structure. It has the advantages of easy operation, high-efficiency sealing, and is convenient for maintenance. It can be used in various industries like water treatment, oil and gas. Available in manual, electric and pneumatic versions, it meets different application needs.
The main features of WAYVALVE 4 in ball valve are:
- It is designed with an automatic pressure relief structure. When the change of pressure or temperature in the pipeline causes an abnormal rise of pressure in the valve body, the medium will open the sealing ring by the pressure of overpressure for automatic pressure relief, so as to ensure the safety of the valve and the pipeline;
- It has a reliable seating design in low pressure. In very low-pressure lines, depending on the seat itself seal can not be guaranteed, there may be a small leakage. Therefore, WAYVALVE designed the valve seat sealing form loaded by the plate spring. Under the condition of low pressure, the pressure of the plate spring makes the valve seat close to the ball, which ensures the reliable sealing and the sealing performance of the ball valve in long-term use;
- It has a reliable seating design in high temperature. In the seating of medium and high-temperature structures, using para polystyrene as seal material which can be used in the temperature of 300 ℃, as well as higher temperatures was designed using metal seal combination of high-temperature resistant material;
- It also has a fire protection structure, anti-blow-out stem, and anti-static international standard structure.

The 4 in ball valve is widely used in multiple fields, mainly including petroleum, chemical industry, natural gas, water supply and drainage, etc. Due to its compact structure and reliable sealing, the 4-inch ball valve is often applied in petroleum refining, long-distance pipeline transportation and natural gas transportation systems to cut off or regulate the fluid. In the chemical industry, the 4-inch ball valve is suitable for the control of various corrosive, high-temperature and high-pressure fluids, such as the cutting off and regulation in chemical pipeline systems. In addition, the 4-inch ball valve is also widely used in fields such as water supply and drainage systems, heating, ventilation and air conditioning systems, the construction industry, food and beverage processing, etc.
Can ball valves be customized to specific sizes?
Yes, ball valves can be customized to specific sizes. WayValve among many valve manufacturers offers customization services to meet the unique requirements of different applications. This is particularly useful when standard-sized ball valves are not suitable, such as in some specialized industrial processes, unique plumbing systems, or specific equipment designs. Custom-sized ball valves can be designed to handle specific flow rates, pressures, and media, ensuring optimal performance and compatibility with the overall system. However, custom-made ball valves usually involve higher costs and longer lead times compared to standard-sized ones.
