The PTFE Sleeve For Butterfly Valves are completely locked into the valve body by 360Â° port defining metal lips. The PTFE Sleeve For Butterfly Valves surrounds the conical plug and serves as a self-lubricating seal against leakage through ports and to the atmosphere. The plug rotates in the PTFE-sleeve firmly embedded and aligned in the valve body so that the plug cannot be seized. That special valve design doesnât allow any sleeve deformation, flow or migration into the waterway duct.
