The disc seal is made of AVK's drinking water approved EPDM rubber featuring an excellent compression set and thus ability to regain its original shape.The high quality DVGW/WRAS approved epoxy coating and fully encapsulated shaft/disc connection ensure high durability. The valves up to DN2400 are suitable for bi-directional application, DN2600 and above must be operated uni-directional.

Variant 756/102-IS1
Connection: Flanged
Material: Ductile Iron
DN: DN700 - DN2800
PN: PN10/16
