FLE-AT-Q 3 Pcs Stainless Sreel Pneumatic Ball Valve

The body casting of stainless steel sanitary pneumatic ball valve adopts advanced technology introduced from Taiwan. The valve seat adopts PTFE elastic sealing structure by default, which ensures reliable sealing and easy opening and closing.

The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally pressurized, the valve stem will not be impacted. A 90° switch positioning mechanism can be set up and locked as needed to prevent misoperation. Applicable to various pipelines with PN1.0～4.0MPa and working temperature -29～180℃.

Suitable for water, steam, oil, nitric acid, acetic acid, ammonia salt water, neutralized water and other media.
