Product Overview

The pneumatic fluorine lining O-type cut-off ball valve is a kind of high-grade ball valve with 360-degree right-angle rotary. The inner wall of the valve body and the components in the valve body in contact with the fluid adopt the high-temperature molding fluorine lined plastic process and are coated with a layer of anti-corrosion materials such as perfluoroethylene (F46), polytetrafluoroethylene (PTFE), soluble polytetrafluoroethylene (PFA), etc., which can completely cut off the contact between the corrosive medium and the valve body shell.

It has the following advantages:

Good sealing performance
Sensitive action
Linear flow passage
Large flow capacity

The valve can be used with two-position five-way solenoid valves and control boxes to realize switch control. It is widely used in the control of acid, alkali, and other corrosive media, as well as poisonous, volatile, and permeable gas and liquid media.

Product Features

Corrosion resistance: Resists corrosion from almost all media (including concentrated nitric acid and aqua regia).
Large flow capacity: Does not limit the flow direction of the medium.
Good sealing performance: The sealing valve seat is subject to PTFE, ensuring reliable sealing, self-lubrication, and minimal leakage.
Suitability for various media: Works well for general gas and liquid, as well as mediums with high viscosity and fibrous or suspended soft particles.
Simple structure and easy maintenance.
Versatile actuation: Equipped with a rack and pinion pneumatic actuator (with multi-spring) and electric actuator with angular travel. It is ideal for various environments and functions as a control and cut-off system for high consumption requirements.
