PTFE FEP PFA lined Flush bottom ball valve

PTFE FEP PFA lined Flush bottom ball valve introduction
PTFE FEP PFA lined Flush bottom ball valve adopts PTFE FEP PFA fluorine plastic as the ball valve liner, and is equipped with the new type of ball structure with the rod, together with its unique elastic seal seat structure, PTFE FEP PFA lined Flush bottom ball valve can have the high sealing performance and the low operating torque in the large pressure difference and the large temperature difference range.TPTFE FEP PFA lined Flush bottom ball valve can be used for switching or adjusting. Teflon lined tank bottom ball valve is suitable for conveying liquid and gas (including steam) in all kinds of industrial pipelines.PTFE FEP PFA lined Flush bottom ball valve can work well in all kinds of acid, alkali, salt and other strong corrosive medium.Full size valves provide maximum flow and can be used to sweep lines to clean or isolate piping for delivery.

PTFE FEP PFA lined Flush bottom ball valve is widely used in the transportation of liquids and gases (including steam gas) in various types of industrial pipelines, especially for the use of severely corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua aqua and other highly corrosive media.

PTFE FEP PFA lined Flush bottom ball valve working principle
PTFE FEP PFA lined Flush bottom ball valve is opened and closed with a ball with a circular through hole that rotates with the stem around the center line of the body to open and close the valve.Special molding process is adopted to make the sealing surface compact and good, and v-type PTFE packing combination makes the valve reach zero leakage;The ball and stem are cast as a whole, which eliminates the possibility of the stem rushing out of the pressure parts due to pressure changes, and fundamentally ensures the safety in use.All plastic lining technology is adopted to withstand the strong corrosion of medium.
PTFE FEP PFA lined Flush bottom ball valve can be driven by manual, worm wheel, pneumatic actuator, electric actuator, etc.


PTFE FEP PFA lined Flush bottom ball valve feature
1. It adopt fluorine plastic lining of the ball valve, with high chemical stability, suitable for any strong corrosive chemical media;
2. Adopt all-pass floating ball valve structure to shut off yuan leakage within the whole pressure range, so as to facilitate the pipeline system to sweep through the ball and maintain the pipeline;
3.The fluid resistance is small, the lining of the ball valve inner wall smooth, smooth flow passage is the least resistance of all valves in the fluid.
4. The switch is fast and convenient, and only need to rotate the sphere 90° to complete the opening and closing action;
5. Special molding process is adopted to line the lining material on the inner wall of valve shell, which can withstand the corrosion of strong acid and strong alkali media.The liner sphere is combined with PTFE seat for good sealing and zero leakage.
6. Pneumatic, electric, hydraulic and other driving devices can be configured to achieve remote control and automatic operation;
7. The ball is integrated with the valve stem to eliminate rotation Angle difference, eliminate the risk of valve stem rushing out of the body due to pressure changes, and ensure the safety and reliability of use;

PTFE FEP PFA lined Flush bottom ball valve application
PTFE FEP PFA lined Flush bottom ball valve is designed to control the opening and closing of various strong corrosive media. PTFE FEP PFA lined Flush bottom ball valve is widely used in petroleum, chemical industry, dyeing, pesticide, acid and alkali industry and so on. PTFE FEP PFA lined Flush bottom ball valve is the most ideal choice for anticorrosive valve.The company strictly according to the national standard production, exquisite processing technology, first-class equipment, staff conscientious and responsible attitude, practical after-sales service, material package test.
