Pneumatic steel lined fluoropolymer double clamp butterfly valve

D671F46 Pneumatic fluoropolymer-lined Butterfly Valve

D671F46 adopts a midline butterfly valve and pneumatic actuator. The current page diameter is DN25-DN800, and the pressure configuration includes PN16, Class150, and JIS10K. The valve body material field is WCB or 304, and the lining options include PFA, PTFE, and FEP.

How to choose PFA, FEP, and PTFE?

All three materials belong to fluorinated polymers, but their properties and processing methods are different. The actual selection should be determined based on the composition, concentration, temperature, pressure, and valve manufacturing structure of the medium, and cannot simply replace the material grade with "fluoropolymer lining".

Is it necessary to use ASCO for solenoid valves?

No. Electromagnetic valves belong to pneumatic accessories, and the brand, coil voltage, explosion-proof level, and interface should be configured according to project requirements. Only when the actual order is adopted and has corresponding proof, can the specific brand and explosion-proof certification be declared.

Pneumatic control configuration

The actuator can choose single acting or double acting according to safety logic and be equipped with filtering and pressure reducing devices, solenoid valves, limit feedback or locators. The adjustment function should be confirmed based on the butterfly valve body, locator, and actual working conditions.

Frequently Asked Questions

Is it certain that D671F46 will all use FEP lining?

The current page lists options PFA, PTFE, and FEP simultaneously, and the actual supplied materials are confirmed according to the order.

Is ASCO explosion-proof solenoid valve the default configuration?

No, the brand and explosion-proof rating are optional accessory requirements.

Can pneumatic fluoropolymer-lined butterfly valves be semi opened for long-term throttling?

It needs to be judged based on flow rate, pressure difference, lining and butterfly plate erosion, and cannot be determined solely by pneumatic drive.
