Pneumatic cast steel WCB fluoropolymer lined flange ball valve

Q641F46/PFA Pneumatic fluoropolymer-lined Flange Ball Valve

This product adopts pneumatic drive and flange connection. The available configurations include WCB, 304 valve body materials, as well as lining options such as PFA, PTFE, FEP, etc. The specific model suffix and actual lining material must be based on the order and product information.

Lining materials cannot be mixed into one type

PFA, FEP and PTFE are distinct fluoropolymers with different processing and service characteristics. F46 denotes FEP; the selected lining should match the medium and operating conditions.

How to choose a fluoropolymer-lined ball valve?

It is necessary to provide the composition and concentration of the medium, temperature, pressure, diameter, and connection standards, and confirm the combination of valve body, sphere, valve seat, and lining materials. The risk of lining damage should also be evaluated separately for particle and abrasion conditions.

How to configure pneumatic accessories?

Single acting or double acting actuators, solenoid valves, filtering and pressure reducing devices, limit feedback or locators can be configured according to control needs. The proportional adjustment function is only established when the actual valve structure and positioning control configuration meet the requirements.
