Product Description

Product Description

Pneumatic Wafer Type Fluorine lined Butterfly Valve 

Summary:
Pneumatic fluorine lined butterfly valve is also known as pneumatic lined anticorrosive butterfly valve. It is in contact with the official media flow components (such as the valve body wall, valve plate, seat) lined with a thicker layer of fluorine plastic, and it has a strong corrosion resistance and wear resistance. Pneumatic fluorine lined butterfly valve seat and disc plate are all made of PTFE, which effectively ensure that the valve shaft and other related parts from the valve cavity media contact and corrosion. Pneumatic fluorine lined butterfly valve according to the connection mode, it is divided into pneumatic clamp type fluorine lined butterfly valve and pneumatic flange type fluorine lined butterfly valve. At the same time, it also can choose switch mode according to the working condition of requirements or execution of external regulation device, to achieve rapid pipeline medium to switch off or adjust flow using proportion type. It can be widely used in the corrosive fluids with temperature of 180 ° C or as well as strong acid, strong alkali medium under normal circumstance.

Application Scope:

The sealing structure of pneumatic fluorine lined butterfly valve can be divided into half fluorine lined butterfly valve and full fluorine lined butterfly valve according to the working conditions. It has the advantages of aging resistance, corrosion resistance, long life, and sealing performance Besides, it can achieve with no- leakage. It is one of the ideal anticorrosion equipment. It is especially suitable for strong corrosion or cleanliness requirements of the working conditions. It is widely used in any concentration of acid, alkali, strong oxidant, organic solvents and other process media. However, it is not suitable for media with high temperature, pressure media, or with granular media. In general, as for a certain temperature and pressure of the medium, we recommend the choice of metal seal material butterfly valve.

Advantages:

1.Pneumatic anti-corrosion butterfly valve has small torque, and it is easy to operate.

2. Pneumatic lined teflon butterfly valve can be installed in any position, and has easy maintenance.
3. Pneumatic anticorrosive butterfly valve seals can be replaced, according to the different working conditions, we can choose half fluorine lining and full fluorine lining.
4. The sealing material of pneumatic corrosion resistant butterfly valve has advantages of aging resistance, corrosion resistance, long service life. Besides, it can be used for weak corrosive fluid and strong acid medium.
