Pneumatic center line wafer-type soft seal butterfly valve D671X-16Q

D671X-16Q Pneumatic Centerline Clamp Soft Seal Butterfly Valve

D671X-16Q adopts pneumatic drive, clamp connection, and center vertical plate soft seal structure. The current page has a caliber of DN50-DN700, a pressure of PN1.0-PN2.5MPa, and material fields including QT450, stainless steel 304, and EPDM.

Mid line soft seal structure and clamp installation

D671X-16Q adopts a center vertical plate soft seal structure, and the pneumatic actuator drives the butterfly plate to rotate through the valve stem. The valve body is installed between the paired pipeline flanges in a clamped manner, ensuring that the valve body is aligned with the butterfly plate opening and closing space during installation.

How to choose EPDM soft seal?
