How much pressure can ball valves withstand when discussing the manufacturer of bidirectional sealed butterfly valves?
Wear-resistant ball valves are an important fluid control equipment widely used in fields such as petrochemicals, electricity, pharmaceuticals, paper making, and urban water supply. Pressure is one of the important parameters for the operation of wear-resistant ball valves, and the pressure it bears varies for different types of wear-resistant ball valves.
Firstly, manufacturers of bidirectional sealed butterfly valves need to understand some basic knowledge about pressure.
Pressure is a state of matter that refers to the force exerted on a unit area. Commonly used pressure units include pascals (Pa), bars (bar), megapascals (MPa), etc. In the industrial field, commonly used pressures range from 0.1MPa to 100MPa.

Then, let's have a specific understanding of the pressure that different types of wear-resistant ball valves can withstand.
Metal hard sealed ball valve
Metal hard sealed ball valve is a type of ball valve that uses metal to metal sealing, mainly used for control under high temperature, high pressure, and strong corrosive media. This type of wear-resistant ball valve can withstand high pressure, usually above 50MPa.
Soft sealing ball valve
Soft sealed ball valves use rubber materials such as polytetrafluoroethylene as sealing materials, suitable for controlling media with temperatures below 180 ℃ and pressures below 10MPa. This type of wear-resistant ball valve is mainly suitable for low-pressure systems and can generally withstand pressures below 10MPa.
V-shaped ball valve
The V-shaped ball valve adopts a V-shaped notch design, which has good medium cutoff performance and can withstand high pressure within a suitable pressure range. Generally able to withstand pressures exceeding 40MPa.
Three way ball valve
The three-way ball valve is mainly used for the conversion of medium flow direction and has the function of multi-channel. This type of wear-resistant ball valve can withstand relatively high pressures, generally able to withstand pressures above 20MPa.
National standard ball valve
National standard ball valve is a common type of ball valve, suitable for medium temperature and medium pressure medium control. This type of wear-resistant ball valve is generally able to withstand pressures below 10MPa.
In summary, different types of wear-resistant ball valves can withstand different pressures, generally between 10MPa and 50MPa. When choosing wear-resistant ball valves, manufacturers of bidirectional hard sealed butterfly valves need to understand the pressure, temperature, and other characteristics of the medium, and choose suitable wear-resistant ball valves according to their needs.
