    The unique SISTO design with enclosed diaphragm and spiral support ensures utmost operating reliability and durability.

    In order that the actuation force can be fully utilised without affecting the plastic diaphragm’s long service life, the TFM diaphragm is backed up by a second, non-bonded, diaphragm made of EPDM.

    A metal pin embedded in the TFM diaphragm helps lifting the diaphragm and thus opens the valve. To avoid damage to the diaphragm during valve closure, the metal pin is fitted to the bonnet assembly by means of a floating nut.

    This 2-piece TFM/EPDM diaphragm is perfectly suited to applications involving high chemical and thermal stress.

    Both TFM and EPDM comply with FDA specifications.
