Product Announcement from Peter Paul Electronics Co., Inc.
The Series EL50 low wattage, explosion-proof solenoid valves has been announced by Peter Paul Electronics Co., Inc., New Britain, Connecticut, for hazardous duty operation and for use in remote locations requiring solar, battery power, or other limited energy sources.
These general purpose or safety valves, for pneumatic and hydraulic applications require only 1.8 watts AC or DC to provide safe and continuous operations at maximum pressures up to 200 psi involving media including air and other common gases, most refrigerants, public utility gas, fuel oils, steam, some hydraulic fluids, and other aqueous non-flammable liquids. Operating within the temperature range of O°F (-18°C) to 221°F (105°C), EL50 solenoid valves respond in 4-16 milliseconds for operating speeds up to 600 CPM, continuous or Intermittent. Construction is of stainless steel, with all interior components of stainless steel; all stainless steel housings are also available.
Basic models in the EL50 Series include the EL51 (2-way normally open), EL52 (2-way normally closed), EL53 (3-way normally closed; exhaust to atmosphere), and EL53 (3-way normally closed; piped exhaust). Orifice sizes, coil voltages, and pressure differentials may be specified per application. In addition, low watt, explosion-proof valve operators, designated OEL50, are available for OEM applications.
