Model Description Drawing
Clock Gauge FIG818/818F The Morrison Clock Gauge is a unique, fully mechanical, liquid level indicator which can be used in a variety of applications. The standard model will measure up to a 12 ft. dimension. Operation is simple: the float moves up and down with the level of the product and is cabled to a wheel which drives the hands on the clock.
Clock Gauge Alarm FIG918/918F Utilizes the Fig. 818 style Clock Gauge with a built-in high level warning alarm. Contains a battery powered, intrinsically safe, alarm unit that is mounted remote from gauge. Alarm is set for desired level during installation and can be reset at any time for a change in alarm level requirements.
AST Overfill Prevention Valve — FIG 9095A Installed at the fill port of an aboveground storage tank (top loading). Shuts off the flow of product when the liquid level reaches a preset warning level (90 - 95% full).
Diffuser — FIG 539 Series Reduces turbulence of fuel in storage tanks, thus minimizing vapor creation. Reduces fuel contamination by directing flow away from debris on tank bottom. Saves on both fluid vaporization and wear and tear of tanks.
Emergency Vents — FIG 244 Series Emergency Vent (pressure relief only)as a code requirement, to help prevent the tank from becoming over-pressurized and rupturing if exposed to fire. Series also contains flanged adaptor, companion flange, and pipe nipple fittings.
Updraft Vent — FIG 354 "Open" vent used on underground and aboveground tanks for motor fueling. Vent allows tank to "breathe" during filling/dispensing operations. Some sizes are CARB approved.
AST Spill Container — FIG 515 & 517 / 518 Series Installed on aboveground storage tanks for the purpose of containing small spills and drips from the fill nozzle. Steel construction, lockable, and powder coated white.
Double Tapped Bushings — FIG 184 Series Used in pipe and tank fitting to reduce or adapt to a connection. Cast iron with NPT threads. The duplex bushing is used to connect 2" pipe to dual 1/2" or 3/8" lines.
Solenoid Valve — FIG 710 Installed on pipeline leading to/from an aboveground tank. This valve is used to prevent accidental spill or siphoning of product from the tank in the event of a fracture in the pipe or other cause for leak downstream and below the liquid level.
1/2" Expansion Relief — FIG 78DI Used on AST piping for relief of excessive pressure. Valve allows product to return back to the storage tank. Ductile Iron construction.
Gate Valve (w/o expan.relief) — FIG 234 and 235 Rising Stem Gate Valve used for manual flow control in petro-chemical liquid handling. This gate valve operates by rotating handwheel counter-clockwise to open or clockwise to close. Valve can be left partially open to control flow rate.
Quick Opening Gate Valve — FIG 237, 238 and 438 Manually operated gate valve with throttle type lever action. For use in petroleum liquid handling. They have a pressure rating of 200 PSI WOG, cold, non-shock.
Ball Valve (full port) — FIG 691 Full port ball valve used for liquid handling with manual open-close in quick quarter-turn handle operation. Threaded (NPT) connections. Valve can be operated in partial open position. Lockable with padlock.
Swing Check Valve — FIG 246 Series Used for single-direction flow in a horizontal pipeline and/or to isolate product in a multi-product handling system. Poppet and seats are metal and may allow some seepage over long periods of time. Expansion relief is available.
Threaded Style Fill Cap — FIG 178 Series Tight-seal style cap with threaded cover. For fill port of small storage tanks. Lockable with a padlock. Body is available in iron or brass. Cover is also available in iron or brass. Buna-N gasket.
Hinged-style Fill Cap — FIG 179 Series Loose-seal style cap with hinged cover. For fill port of small storage tanks. Lockable with a padlock. Aluminum or cast iron. Available with male or female threads.
