Flanged butterfly valve package with Pneumatic AT actuator, using catalog ordering-code example D641X-10ZT-DN50.

Kailing pneumatic flanged butterfly valve package
PUBLISHED PRODUCT

Pneumatic Flanged Butterfly Valve is a Kailing automated butterfly valve package. The catalog ordering-code example D641X-10ZT-DN50 maps to transmission code 6 and flange connection. Confirm DN size, seal material, shell material, disc material, pressure class and actuator control before quotation. Derived from the PDF ordering code for pneumatic transmission plus flange connection and the flanged butterfly-valve dimension table; confirm exact material code and DN before quotation.

Frequently Asked Questions

  • FAQ What model or ordering-code example supports Pneumatic Flanged Butterfly Valve?
    The PDF ordering code and dimension table support D641X-10ZT-DN50 as a flanged pneumatic ordering-code example; confirm the final material code and DN before quotation.
  • FAQ Why is seal material important for butterfly valves?
    The catalog lists different seal temperature ranges, so the medium and operating temperature should be confirmed before model selection.
