First, product overview:

　　Q644F pneumatic fluorine lined tee ball valve by the combination of pneumatic actuator and fluorine lined tee ball valve. Three-way lined fluorine ball valve generally adopts two seat structure, can also adopt four seat structure according to user requirements. Four seat sealed three-way ball valve with beautiful shape, compact and reasonable structure, it can not only realize the medium flow direction switch, but also can make the three channels connected, but also can close any channel, the other two channels connected, flexible control pipeline medium confluence or shunt. Fluorine plastic is used as the ball valve lining, and with a new type of rod ball structure, coupled with its unique elastic lip sealing seat structure, so that it has the advantages of ordinary ball valve, can have high sealing performance and low operating torque in the range of large pressure difference and large temperature difference. Can be used as a switch or adjustment, in a variety of acid, alkali, salt and other strong corrosive media can work well.

Second, product features:

1. Ball valve with fluorine plastic lining layer, with high chemical stability, suitable for any strong corrosive chemical media;


2. The all-pass floating ball valve structure, in the whole pressure range of the element leakage closed, convenient for the pipeline system in the ball line sweep and pipeline maintenance.


3. The fluid resistance is small, the lining ball valve wall is smooth, and the flow passage is smooth. It is the least fluid resistance of all the valves.


4. Quick and convenient switch.


5. The lining material is lined on the inner wall of the valve shell by special molding process, which can resist the corrosion of strong acid and alkali medium. The lining sphere is combined with PTFE seat for good sealing and zero leakage. The ball needs to be rotated 90 degrees to complete the opening and closing actions.


6. Pneumatic, electric, hydraulic and other driving devices can be configured to achieve remote control and automatic operation.


7. Ball and valve stem integration, in addition to the rotation Angle difference, to eliminate the risk caused by pressure changes caused by valve stem out of the body, to ensure the safety and reliability of use.

Fourth, control mode:

It can be divided into L type and T type. See the following figure for the flow direction of the medium:


a.L type is suitable for switching of medium flow direction, and can connect two channels perpendicular to each other.


b.T type pneumatic three-way ball valve lined with fluorine is suitable for medium shunt confluence or flow direction switching. A T-channel can connect three channels to each other or two of them.
