1 /2- and 4/2-multi-way valves ; servo-assisted; block assembly or NAMUR flange; DN 4; flow rate: 00 l/min Advantages / Benefits II 2G EEx ia IIC T6 PTB0 ATEX 275 approved Available for block assembly and with NAMUR flange High flow rate at compact design Maintenance-free and no wear due to high level dry run properties With manual override Various options for the service ports 2 and 4 High switch reliability Block assembly version fieldbus compatible Low weight Design/Function Applications EExi includes high switch reliable diaphragm seat valves as /2- and 4/2-way version. The valve consists of three modules, valve body with servo-diaphragm, plungers and seat seals as well as numerous connection possibilities for the service ports 2 and 4. The body and valve internal parts are made of high quality thermoplastic, the return spring is made of stainless steel. A 6 mm rocker solenoid valve type 606 with rectifier and an EExi coil is used as pilot. Tag connectors are used as electrical contact (acc. to DIN Form C) with cable plug type The extendable type 5470 EExi can be used for block modules or for entire valve blocks (tag connectors on top, coil spacing 9 mm). The block assembly is made with pneumatic modules type MP05 through integrated lock technology and screwing. NAMUR EExi can be easily mounted to a process valve with the same interface. Applications: Chemical industry Pharmaceutical processing equipment Industrial waster water treatment Oil and gas industry Page / 6
