Pneumatic butterfly valve

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.
• 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
