First, Q644/5F flange three-way pneumatic ball valve overview:

The Q644/5F flanged three-way pneumatic ball valve consists of a double (single) acting pneumatic piston actuator and a three-way ball valve. Its valve body is divided into L type and T type. The pneumatic piston actuator is made of low friction material and is made of bearing sleeve. The inner and outer surfaces of the cylinder are hard anodized and anticorrosive, which greatly improves the service life of the cylinder. This product has stable performance and is widely used in petrochemical, metallurgical, electric power and other industrial sectors.

Second, the main features of Q644/5F flange three-way pneumatic ball valve:

1. Compact structure, rapid opening and closing, smooth flow path and low fluid resistance.

2, good sealing performance: the use of four-sided valve seat material PTFE elastic deformation to achieve a leak-free seal.

3, a multi-purpose valve: any port can be used as an inlet without leakage, the three-way can be made into an L-shaped port, or can be made into a T-shaped port.

4. Convenient maintenance: After the system is relieved of pressure, it can be inspected and repaired without removing the entire valve body.

5. It is generally applicable to the switching of medium flow direction and the shunting of medium in water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other pipeline systems.

Sixth, Q644/5F flange three-way pneumatic ball valve medium flow principle:

The three-way ball valve is divided into L type and T type, and the flow direction of the medium is shown in the following figure. The L-type three-way ball valve is suitable for the switching of the flow direction of the medium, and can connect two channels perpendicular to each other: the T-type three-way ball valve is suitable for the shunting, confluence or flow direction switching of the medium, and the T-shaped channel can make the three channels communicate with each other or Two of the channels are connected, and the three-way ball valve generally adopts two valve seat structures, and the four-valve structure can also be adopted according to user requirements.
