2/2-Way, Servo-Assisted5282Brass Solenoid Valve with Rocker Systemfor slightly contaminated fluidsNormally closed52822/2-Way, NPT 1 /2 - NPT2, 2.8-140 psiGExtremely long service lifeSeparating diaphragm isolatessolenoid from operating fluidLockable manualoverride as standardAdjustable open-close rateModular, servo-assisted valve system with Burkert‘srevolutionary rocker system completely isolating the pilot fromthe fluid. The valve is therefore less sensitive tocontaminated fluids.Technical DataPressure range 1)Temperature mediaAmbient temperatureBody materialSeal materialCoil materialPower consumptionProtection class withcable plug2.8-140 psiG, max.+32 o F ... +194 o F+131 o F, max.BrassNBREpoxyDC: 8 WAC: 21 VA(inrush),12 VA(hold)IP 65 (standard delivery:cable plug DIN 43 650 A))Dimensions [inch]Options- Normally open (N.O.)- Electrical feedback- Impulse coil (zero watt)BA 1.14Variable dimensions [inch]Port Conn.
