Morrison - Solenoid Valve

Solenoid Valve, SS
Normally closed solenoid valves are used to help prevent the accidental siphoning of a product from a tank in the event of a leak downstream 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.


Solenoid Valve, SS (PTFE), Flanged
Normally closed solenoid valves are used to help prevent the accidental siphoning of a product from a tank in the event of a leak downstream 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.

Standard Features

  • Normally closed, hung piston design
  • Install in a horizontal pipeline in the upright vertical position
  •  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
  •  Several optional coil voltages available
  •  The enclosure is watertight and rated for hazardous locations—NEMA 3, 4X, 7 and 9; groups C and D
  •  710FSS has flanged body connections
  •  710FSM has manual override feature. Available in sizes ranging from ¾″ 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

Morrison - Overfill Valve

Overfill Prevention Valve - SA Series
The 9095SA Overfill Prevention Valve is installed at the fill port of a storage tank. Used in a pressurized tight fill application, the valve helps prevent tank overfills by closing when the liquid level reaches a pre-set warning level (90-95% full). The valve is installed on a standard 2” NPT male connection and has a built-in bleed hole that allows the fill hose pressure to be relieved after the valve closes. This bleed hole also provides anti-siphon protection for the valve. When installed to manufacturer requirements, the Morrison Fig. 9095SA Overfill Prevention Valve can eliminate hazardous liquid spills.

Standard Features

  • The valve design allows for a full flow fill until it closes.
  • Designed for fuel not requiring a drop tube.
  • A field adjustable float allows the installer to set the desired shut-off point. The vertical float allows for installation in openings in proximity to the tank walls.
  • The valve shut-off length is field adjustable from 2 to 12 inches.
  • 2” 305C--0000 AC Locking Cap sold separately.

Morrison - Anti-Siphon

Anti-Siphon Valve with Expansion Relief
Anti-siphon valves are used to help prevent the accidental siphoning of a product from a tank in the event of a leak downstream below the liquid level.

Standard Features

  • Valve functions in horizontal and vertical position
  • Integrated expansion relief set at approximately 25 PSI
  •  Factory preset to several ranges of water column
  •  Maximum working pressure— 200 PSI
  •  -10°F to 200°F operating temperature range
  •  Normally closed
  •  Priming tees and assemblies are available

Morrison - Emergency Shut-off Valve

Emergency Shut-Off Valve
The 446 normally open valve is designed to shut off liquid flow in the event of a fire or excessive temperatures. This emergency shut-off valve is installed in the fuel line from a storage tank to fuel burning equipment; such as back-up generators, boilers and other flammable liquid burning appliances.

Standard Features

  • cULus  listed to ULC/ORD-C842 – Valves for Flammable and Combustible Liquids (See details below in Code Compliance)
  • 165° F fusible link activates spring closure
  • 1/2", 3/4”, or 1” female NPT threaded connections
  • Compact size reduces operational footprint requirement
  • Easy to install and maintain
