Description

ptfe ball valve seat is manufactured by ram extruding method with PTFE granular resin.it skived by machine.

ptfe ball valve seat for electronic and electrical industries are manufactured by ram extruding method with PTFE granular resin, It skived by machine, It has the most chemical-resistant and the best dielectrical  properties.It has the lowest coeffcient of friction of all known solid materials and a wide range of practicable temperature from -180degree ~+260degree.

Because of such excellent properties, PTFE has a wide application as a sealing material.

Application

Used to seal steel, glass-lined steel, and FRP piping in chemical-process piping. Designed to meet the needs of various piping materials, they are ideal for standardizing gasket material across steel, glass-lined steel, and FRP systems - any application in which a non-metallic gasket can be used.  

Specification

We can produce any special articles, only send us your size and drawing, then we can produce samples for you.

We can supply a wide range of butterfly valves, gate valves, globe valves, check valves, ball valves, relief valves, Strainers, hydraulic control valves, and pressure reducing valves.

Feature

PTFE is the chemically inert of the O-ring materials.

Resistant to most chemicals including acids, bases, oils, steam and other chemicals.

Very tough and abrasive resistant.

Has minimum friction coefficient of all know pure material

Non-viscous, no aging

Now molds can be made according to customers requirements.
