Pneumatic U Type Flanged Butterfly Valve


Features & Benefits


  • Simple structure, good interchangeability, and low price.

  • The stem seal is not easily deformed to avoid the normal stem leakage, and the overall support is good, stable and firm.

  • With less seat rubber, there is less potential for expansion and it is easier to control the torque within the proper range.

  • The use of two-piece valve stems with no pin connection, the structure is simple and compact, and mainte­nance and disassembly are very convenient.

  • The butterfly board has the function of automatic centering, and the butterfly board and valve seat are closely matched.a

  • The phenolic back valve seat has the characteristics of not falling o仔 tensile resistance, leakage prevention

    and easy replacement.

  • Surface: Polyester, RAL9006, 100μ

  • Face-to-face: EN558-1

  • Counter flange: DN40-DN300, PN10/16/ANS1150

  • BS10 TABLE D/E JIS 10K 16K

  • DN350 -DN600 PN10 or ANS1150 BS10 TABLE D/E


  Product Description

Product Description

  • All listed output torques are expressed in inch pounds of torque (in. lbs.).

  • Charts for available air pressure are expressed in pounds per square inch (P.S.I.).

  • FLOWX actuators offer ±5° adjustment in the open and closed positions on DA52 through DA-125 models.
