and special applications allows pract gaseous media to be sealed. BUTTERFLY VALVE Q 011 QUAD-RING Seals are vulcanized as They are characterized by their annul TECHNICAL DATA lipped profile. Their dimensions are Nominal diameter: DN 80 inside diameterDN 400 and the cross-sect d1 Face-to-face: Flange accomodation: Tightness check: Temperature range: Operating pressure: High grade double block butterfly valve, with test/lubrication port for laboratory, clean room and pharmaceutical applications. EBRO works standard QUAD-RING Seal dimen QUAD-RING Seals are supplied in d American O-Ring Standard AS 568 B - Can be installed in any desired position - Multiple shaft bearings - Can be disassembled, material-speciﬁc recycling possible In contrast to the O-Ring, QUAD-R following advantages: GENERAL APPLICATIONS IN HVAC PLANTS: - Pharmaceutical industry - Clean room technology - Research laboratories - Laboratories - Avoids twisting in the groove. Due to the seal does not tend to roll in reciprocating movement. - Low friction. - Very good sealing efficiency. Due pressure profile over QUAD-RING The integrated coupling provides the port for the air test gauge and a high sealing effect is achieved. the lubrication press. - A lubricant reservoir formed betwe improves start up. Q 011 - Unlike an O-Ring, the mould line flas between and away from the critic
