It is mainly composed of a valve body, ball, valve stem, sealing gasket, and driving device. The valve body serves as the outer shell; the ball is equipped with a channel; the valve stem connects the ball and the driving device; and the sealing gasket prevents fluid leakage.
The opening and closing of the valve and the control of fluid flow direction are achieved by rotating the ball. The ball rotates around the center line of the valve body: when the channel on the ball aligns with the channel on the valve body, the valve opens, allowing fluid to pass through; when the ball rotates by a certain angle and the channels are staggered, the valve closes, blocking the fluid.
- L-type three-way ball valve: It can only connect two mutually perpendicular pipes and is used for flow path reversal.
- T-type three-way ball valve: It can connect three orthogonal pipes to each other and cut off the third channel, functioning for splitting and merging flows.
- Non-decompression three-way ball valve: Used to control the flow direction and flow rate of fluids.
- Three-way ball valve with decompression hole: Can guide fluid from one channel to another, playing a decompression role.
- Hydraulic balance three-way ball valve: Used for flow regulation.
- Proportional three-way ball valve: Precisely controls the valve opening according to input signals.
- Double-sealing surface three-way ball valve: Equipped with two sealing surfaces to prevent fluid leakage.
- Integral three-way ball valve: The ball and valve body are integrally formed, reducing the possibility of leakage.
- Pouch-type multi-way ball valve: The ball has multiple pouch-type structures inside, which can flexibly realize the mixing or separation of multiple fluids.
- Low fluid resistance.
- Simple structure, small size, and light weight.
- Tight and reliable with good sealing performance.
- Easy to operate, opening and closing quickly.
- Convenient for maintenance.
- Wide range of applications.
- Generally, it cannot be used for throttling.
- In some working conditions, there may be issues with wear on the sealing surface.
- For special media or extreme working conditions such as high temperature and high pressure, three-way ball valves with special materials or structures need to be selected.
Widely used in industries such as petroleum, chemical engineering, metallurgy, energy, pharmaceuticals, and papermaking to control the flow direction, splitting, merging, and 截断 of various fluids.
- In HVAC systems, it is used to adjust the flow rate and direction of the air-conditioning water system to achieve temperature control in different areas.
- In water supply and drainage systems, it is used to control the distribution and switching of water flow.
- In the food and beverage industry, it is used for the transportation and distribution of materials.
- In the water treatment industry, it is used for fluid control in sewage treatment processes.
