710 / 710MO Solenoid Valve - Normally Closed

Brand: Morrison Bros. Co.
Normally closed solenoid valves are used to help prevent the accidental siphoning of product from a tank in the event of a fracture in the pipe or other cause for leak downstream and below the liquid level. 

Generally installed on the dispensing side of a fuel system pipeline. 

The valve opens upon the receipt of an electronic signal such as when a dispenser or pump is switched to the on position.

NOTE:  Product can only be pumped in one direction, the direction of the flow arrow. Not designed for use as an overfill prevention or process control valve.
Features
  • Normally closed, hung piston design
  • Install in a horizontal pipeline in the upright vertical position
  • Minimum operating temperature is -40° F
  • Zero pressure differential
  • Integral thermal relief allows the valve to relieve expansion pressure in the opposite direction of flow
  • Continuous duty Class H standard coil operates at 120 volts
  • Enclosure is watertight and rated for hazardous locations - NEMA 3, 4X, 7 and 9; groups C and D
  • Several optional coil voltages available
  • 710MO has manual override feature. Available in sizes ranging from 3/4″ to 2″ for operation during a power outage
  • Recommended for use with liquids having a maximum viscosity of 60 centistokes
  • A strainer with a 100 mesh screen is recommended at the valve inlet
