Frequently used on Hyster & Yale forklifts. There should be an exposed adjustment screw near the small solenoid on top.  There might be a small metal tag that says 30N50 or 30A30 near that screw.

If you find that your forklift is hard starting or running weak/rough, it’s possible that your regulator has become clogged or that the internal seals and diaphragms are failing.

This Aisin style regulator/vaporizer is probably the most popular style currently in use. Frequently found on Toyota, Hyster, Yale, & some Clark lifts within the last 20 years.

PLEASE NOTE:
Check closely to make sure that you are buying the correct version of this regulator/vaporizer. Otherwise, there will be a 25% restocking fee if returned. If unsure, please call us and we will assist you. Frequently there will be a metal tag on one of the screws with a stamped number. If you can find it, that will assist in identification.

There are several versions of this regulator. They all have the same basic casting on the back plate:
692U
Model-C
W.P. 250 psi
W.C.O. 31 lbs

This can make identification difficult. The major differences are the location of the coolant/LP ports and if they are electronic or vacuum controlled (open or closed loop). Other differences are adjustment screws and drains.

Also note that there is a UNIVERSAL REBUILD KIT for this style regulator.  You would also want to get the VALVE REPAIR KIT when rebuilding this regulator.  There is also an ELECTRIC LOCK-OFF SOLENOID that can fail.
