PTFE Lined Flanged Center Shaft Butterfly Valve can be used for shut-off and throttling control. It can ensure sealing more reliable and achieve non-leakage because of the fully lined fluorine materials both for seat and disc. The butterfly valve can realize rotary under the condition of low torque by the resilient-seated design , which means a longer service life ,so as to cost-effective of choosing actuator.
The PTFE Lined Flanged Center Shaft Butterfly Valve With Worm Gear Actuator features a valve body(seat) and inner parts(disc) that come into contact with the fluid, which are lined with PTFE (polytetrafluoroethylene) through a high-temperature molding process. Additionally, the seat and disc of the metal valve body undergoes gear machining to ensure complete bonding between the lining material and metal, thereby enhancing both service life and performance. This valve effectively isolates corrosive media from contacting the valve body while preventing any corrosion of metallic materials within it. With excellent sealing performance,precise flow characteristics, it finds extensive applications in conditions involving strong corrosive media such as acids, alkalis, salts as well as volatile and penetrative gas or liquid media.
ADVANTAGES:
1. Excellent resistance to chemical corrosion, low friction and operate in a wide range of temperatures.
2. Small size and light weight, easy to install and maintenance
3. Excellent sealing performance with non-leak provides long service life.
4.Simple structure and can be quickly Open or shut-off by 90 degrees rotation.
5.Pneumatic and electric actuators can be configured according to customer requirements to meet the needs of remote control.
