Transcription

1 qwer Air and Inert Gas Valves Brass, or Stainless Steel Bodies 1/" to 1" NPT Features Designed solely for installation in intrinsically safe areas, with properly approved and sized current and voltage-limiting safety barriers. Acceptable for use in hazardous locations, as classified by the National Electrical Code: Classes I, II, and III, Division 1, including Groups A through G. Electronically enhanced solenoids have efficient cartridge operators and nonpolarized coils with triple redundant blocking diodes. Capacitor stores power required to open the valve, while blocking diodes prevent it from flowing back into the wiring in the hazardous area. Mountable in any position. % # ) 2/2 3/2 /2 SERIES Construction Valve Parts in Contact with Fluids Body Brass Stainless Steel Seals and Discs NBR, FKM, or CR Sleeve 30L Stainless Steel Core and Plugnut 30F Stainless Steel Core Springs 302 Stainless Steel Pilot Seat Cartridge CA (Series 8316 and 83 only) Rider Rings PTFE Spring Retainer CA Solenoid Enclosures Standard: Watertight, Type. Optional: For 316 Stainless Steel, metal Watertight Box, Type X (on brass bodied valves), specify prefix "WS" instead of "WP". For DIN IP65, specify prefix "ISSC". For Liquid Crystal Polymer, Watertight, Type 1, 2, 3,, and X, specify prefix "WB". See Optional Features Section for other available options. Electrical Normal Operating Voltage 2 volts DC, ±10%. Maximum Allowable "Off" State Current to the Valves must be less than 1 ma. Electronically Enhanced "IS" Solenoid: Maximum Capacitor Charge Time 1 second Minimum Time between Cycles 1 second Minimum Drop Current to Reset Electronic Coil 2 ma Nominal Temperature Rise at 2 VDC and 300 Ohms 2 C (36 F) Maximum Recommended Wire Run (#18 Wire) 1.5 miles from barrier to valve Important: Minimum series resistance of 200 ohms required in wiring circuit if a safety barrier is not used for non-"is" system. Maximum Operating Current (amps)= V - 2. R B+ R L+ 150 Maximum Charging Current (amps)= V R B+ R L+ 52 V = Supply Voltage R B= Barrier or Current Limiting Resistance R L= Line Resistance (wiring) Nominal Ambient Temperature Ranges: 831, 8362, 8317: -0 F to 10 F (-0 C to 60 C) All other: - F to 10 F (-20 C to 60 C) Refer to Engineering Section for details. Approvals: FM approved under J.I.3W8A8. AX (3610). CSA certified under File LR C. CENELEC EEx ia IIC T6 approved. Meets applicable CE directives. Refer to Engineering Section for details. Important: These solenoids are intended for use on clean, dry air or inert gas filtered to 50 micrometers or better. To prevent freezing, the dew point of the media should be at least 18 F (-8 C) below the minimum temperature to which any portion of the clean air or gas system could be exposed. Instrument air in compliance with ANSI/ISA Standard S (R1981) exceeds the above requirements and is, therefore, an acceptable medium for these valves.
