04 Proportional technologies Type 140 Fail Safe Proportional current to pressure closed loop converter, intrinsically safe with ATEX, FM and CSA approvals.Fail safe operation so that in the event of a control signal failure output pressure falls to zero. Ideally suited to process control applications in hazardous environments where certified products are required. > Supply pressure; up to 10 bar > Output pressure range; 0.2 to 2 bar > Supply port; G1/4 or 1/4 NPT > Input control signal; 4 to 20 mA > Flow rate up to; 300 Nl/min > Air consumption; < 2.5 Nl/min at 50% input control signal > Response time; < 1 second > Operating temperature range; -40 to +85°C > Linearity; average < 0.1% of span > Hysteresis; average < 0.1% of span > Power Consumption: < 0.13 Watts > Certification ATEX, FM,CSA > Marine Approvals; DNV-GL, BV 422IS Fail Freeze Uniquely available as the only ATEX Intrinsically Safe fail freeze proportional valve in the world; ATEX IS means that this device can operate safely in hazardous environments and can even pilot flammable media such as natural gas or methane. > Supply Pressure: 4 bar max. > Output Pressure Range; 0.2 to 1 bar > Supply port; G1/4 or 1/4NPT > Input Control Signal; 4 to 20mA > Flow Rate; up to 250 Nl/min > Enclosure protection; IP65 with piped exhaust > Operating Temperature range: -10 to +70 oC > Linearity; less than 0.5% of span > Hysteresis; less than 0.5% of span > Power Consumption: <0.15 Watts > Certified: ATEX IS > Options: Captured Bleed, Conduit, etc. Type 220 Modular I/P Pilot The Type 220 is an extremely low power pilot technology designed for use within a wide array of custom pneumatic systems. The patented design and operation of this open loop pilot means that it can accurately control in excess of 1 bar pressure whilst using just 6 milliwatts of power. This extreme low power capability makes the technology easily certifiable and allows designers greater flexibility when developing their systems electrical parameters. > Supply Pressure: 10 bar max. > Output Pressure Range; 0 to 1 bar > Input Control Signal; 0 to 1.7mA > Response: <650ms > Operating Temperature range: -40 to +85 oC > Temperature sensitivity: <0.2% span/o C > Linearity; less than 2.0% of span > Hysteresis; less than 0.35% of span > Air Consumption: 1.5Nl/min > Power Consumption: < 6 milliwatt > Base design: System Specific > Electrical Connections: System Specific Process Pressure Control Type 140 422IS Type 220
