The Relief Valve is a SAFETY vent for excessive line pressure on the liquid side.
Description: 1/4 NTP 300 psi
[2 068.4 kPa]
Part No.: 0-48643
Hydrostatic Relief Valves: Pressure safety-relief valves are preset to 300 psi [2 068.4 kPa]. These protect piping from “ram,” “liquid hammer,” or surge effects that occur when valves suddenly close, instantly stopping an incompressible liquid flow. Liquid propane “flashes” (from a complete liquid to a partial- vapor state) after leaving the tank and passing through a restriction (such as the Strainer and Inlet Hand Valve),so it is somewhat compressible.

Modulating Motor
10
Description: Modulating Motor Transformer
Part No.: 2541-00056 or 2541-00161
Modulating Motor (Item 10) is located on the plumbing train and is an electric motor powered from a 120V - 24v transformer. The Motor receives an OPEN or CLOSE command from the Temperature Control. With this signal the Modulating Motor drives the Modulating Valve (more opened or closed) to maintain desired drying air temperature.
The Maxon butterfly valve regulates the temperature of the burner
Description: 1 1/4" NPT Maxon
Part No.: 2431-00037
The Butterfly Valve (Item 11) rotates approximately 90 degrees from full-closed to full-open, to vary the inches of water-column pressure to the Burner. The Modulating Motor and Valve are connected with adjustable linkage.

The heat solenoid valve opens and closes to provide fuel to the main burner.
Description: 1 1/4" N 120v
Part No.: 2430-00007
Heat Solenoid Valve (Item 12): controls gas flow to the main Burner manifold on LP and natural gas Dryers. This valve is opened and closed by an electrically actuated solenoid as an automatically controlled safety device in the plumbing train.
