• Designed as a filler valve for LP-Gas with upper check and manual shutoff.
• Excess flow valve allows for maximum filling rates regardless of the length of the coupling the valve is installed in.
• Excess flow seat us fully contained in the tank coupling for maximum protection in the event of external damage to the valve.
• Breakaway groove protects the ACME in the case of a drive-away with the filler hose still connected.
• V-ring spring loaded stem assembly requires no repacking of field adjustment.
• Plugged ¼" NPT boss allows for a pressure gauge to be installed.
• The one-inch outlet port plugged.

A DOT rule became effective January 1, 2013.  The rule adopted nearly six years ago regards the shipping paper basic description.  Amazingly, the rule didn't add or require new information, it simply changed the order of the basic description in the shipping paper sequence to harmonize with international standards.

The previous shipping paper order sequence was: Shipping name, Hazard class, ID number, Packing Group (note that there are no packing group requirements for propane).

The new shipping paper order sequence that became effective January 1, 2013 simply moves the ID number to the top so that the new order would be:

• ID number
• Shipping name
• Hazard class
• Packing Group

• V-83 for Shipping Paper for Bulk Truck
• V-83-CYL for Shipping Paper for Cylinder Trucks

Presto-Tap announces a comprehensive technician kit designed to be carried by drivers and service personnel to perform NFPA leak testing on all stages of a gas system.  The Kit includes all four test gauges (300 psig, 30 psig, 5 psig, & 0-35 inches water column) along with various barbs, adapters, a universal flex hose w/ bleeder assembly, all packaged in a 12 inch gate mouth bag with internal and external pockets.  Utilized for leak testing at pressure locations where a PRESTOTAP® LDS (Leak Detection System) products have been permanently installed - especially helpful for testing at underground tank installations.

The Universal Service Tech Kit includes the following: 

• 6800 KG W/Adapter - 300# Ambient Temperature gauge used for Leak Testing at tank pressure with Presto Tap® pigtails, TPF fittings and RegO® "Ready to Go" series valves.
• PT30 KG W/Adapter - 30# Gauge for determining first stage regulator lock up and flow along with leak testing.
• PT-5# KG W/Adapter - 5# gauge for determining lock up and flow on Two Pound Systems.
• PT-OZ KG W/Adapter - 0-35 inch water column gauge for measuring second stage regulator lock up and flow along with low pressure leak testing.
• MHA Kit - Adapter used to facilitate use of master manometers (water manometer) or magnehelic gauges.
• 3/16" Allen/Hex Key - for plug removal in regulators.
• Universal Flex Hose - 36" flexible hose with gauge bleeder and adapters utilized to universally connect with all gauging equipment above and Presto Tap LDS2000/RV product installed in the system.
• LDS2000/RV - (6) UL Listed fittings with #54 orifice legal installed at any point in the system.
• Kit Bag - 12" Tool Denier Nylon Tool bag with 6 outer and 15 inner pockets.

The kit also includes laminated suggested leak testing procedures from NFPA 54 Annex D.

Protect your Motor Investment &

Protect your Motor Warranty

If you are making investments in new pumps and motors for the Autogas market; make sure you are wiring your motors in accordance with the electrical codes.  Motors 2 HP and over require thermal overload protection.

Have you ever looked inside an electric motor junction box and noticed extra wires, sometimes yellow, grey or brown? These are probably additional protection options for your motor; such as thermostats and crankcase heaters.  

In addition to the thermal overload protection (usually provided within manual and magnetic starters) some motors utilize internal thermostats.  These thermostats are designed to protect motors from internal overheating due to undersized service wiring, overloaded conditions or even low voltage issues.  BUT, for the thermostats to function they must be utilized.  For a thermostat to properly function it must be wired into the control circuit of a magnetic starter with either relays or a momentary start/stop switch.  When the thermostats sense an overheat situation they open the control circuit, thus dropping out the magnetic starter relay and causing the motor to shut-down prior to being damaged.  We find many times on motors returned for warranty issues that the installer has failed to utilize the protective thermostats, and in some cases voiding the motor warranty.

Another protection option we see quite regularly on LPG motors is internal motor crankcase heaters.  These heaters are NOT to be confused with overload heaters you find in starters.  Since LPG pump motors are cycled On & Off quite often in cold environments during the winter, they generally experience condensation of humidity inside the motor housing which occasionally leads to a failed motor due to either short-circuiting or freezing of the moisture on cold nights/days locking up the motor.  In other words, when cold motors are started and stopped repeatedly, they warm up and the cold humid air condenses to moisture inside the motor. 

To prevent moisture from condensing inside the motor; motor manufacturers have installed heaters inside the housing to keep the motors warm and dry when not running.  This prevents the buildup of condensation inside the motor.  But, just as the thermostats discussed above will not function if they are not connected; NEITHER will the HEATERS protect a motor from condensation if they are not connected to a power source.  The heaters must be connected to a separate power source to function when the motor is NOT running.  They are usually wired through a N/C (normally closed) relay on a magnetic starter so they are powered when a motor is NOT running; and shut off during the time the motor is running.

If you have additional questions on electric motor thermostats or crankcase heaters; contact your GEC sales representative, customer service representative or project manager.
