SM-10 (without valve position feedback potentiometer) SM-10R (with the valve position feedback potentiometer) SM-10R electric actuator SM-10 Model: SM-10 SM-10R SM-10 with aluminum butterfly valve actuator supporting the use of 0 butterfly valve into DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100mm, DN125D, N150,11 kind of path. From the type of gas into liquefied natural gas, gas three categories. Depending on the gas, different gas flow matching the corresponding diameter butterfly valve. The gas coal mine gas should be considered corrosive gases discs of stainless steel Power supply voltage: 220V Protection class: ± P54 ~ IEC592 duty cycle: 100% Protection Level: 1 Power consumption: 4.8VA cam contact load: 60 ~ 250V 2A maximum electrical connections: 1.5mm2 cables Torque: 3Nm Weight: 1.4kg (not with valve) with flash position feedback potentiometer: 1KΩ life> 1 million times the number of mechanical action:> 500,000 times without failure mechanical action angle: 0 ° ~ 90 ° mechanical operation time: from 0 ° ~ 90 ° or 90 ° ~ 0 °, 30 seconds / 60 seconds selectable
