Pneumatic fluorine-lined three-way reversing ball valve (T type / L type)overview

The fluorine-lined three-way reversing ball valve is composed of a quarter-stroke piston pneumatic actuator and a three-way ball valve. It is a rotary cut-off and regulating valve with the advantages of tight closing, compact structure, light weight and convenient maintenance. The inner wall of the valve body and the inner valve components in contact with fluid adopt high-temperature molding process of fluorine plastic lining, and are coated with a layer of polyperfluoroethylene propylene (F46), polytetrafluoroethylene (PTFE), and soluble polytetrafluoroethylene (PFA). ) And other anti-corrosion materials, which can cut off the contact between corrosive media and the valve body shell, so the sealing performance is good. The valve can be equipped with valve positioner input control signal (4-20mADC or 1-5V DC) air source to control the operation, and can also be equipped with stroke limit switch, solenoid valve, pressure reducing valve and 0.4-0.7MPa air source. Realize the switch operation, and send out two pairs of passive contact signals to indicate the switch of the valve. The two-seat sealed three-way reversing ball valve has a compact structure, beautiful appearance and good sealing performance. It can switch the flow direction of the medium in the pipeline, and can also connect or close the two perpendicular channels. The four-seat sealed three-way reversing ball valve has beautiful appearance, compact and reasonable structure. It can not only switch the flow direction of the medium, but also make the three channels communicate with each other. At present, any channel can be closed to connect the other two channels to flexibly control the confluence or divergence of the media in the pipeline. It is widely used in the control of strong corrosive media such as acid and alkali, and gas and liquid media such as toxic, volatile and permeable.

Pneumatic fluorine-lined three-way reversing ball valve (T type / L type)performance and characteristics

1. Corrosion resistance: almost can withstand the corrosion of all media (including concentrated nitric acid and aqua regia);

2. The flow capacity is large, and the flow direction of the medium is not restricted;

3. Good sealing performance and small leakage: The sealing valve seat is made of PTFE, which has reliable sealing and self-lubrication, and low leakage;

4. In addition to being suitable for general gas and liquid, it is more suitable for medium with high viscosity and fibrous and suspended soft particles;

5. Simple structure and convenient maintenance;

6. Equipped with multi-spring rack and pinion pneumatic actuators and angular stroke electric actuators, which are convenient for various environments. It is currently a relatively large control and cut-off system.
