Hot gas flow through the valve can be detected by listening to the gas flow through the regulator or by feeling the outlet pipe for warmth When it is not possible to simulate minimum load conditions an approximate setting may be obtained by adjusting the valve until gas flow begins observing the gauge reading and then turning the adjusting stem counterclockwise for the required number of turns to obtain the desired minimum pressure This setting should be checked and readjusted as needed under actual conditions IV Typical Malfunctions Of Solenoid Valve SPORLAN Solenoid Valves Coil Burnout a Coils burnouts are extremely rare unless caused by one of the following b Improper electrical characteristics c Continuous over voltage more than 109 d Under voltage of more than 1596 This applies only if the operating conditions are such that reduced MOPD causes stalling of the plunger which results in excessive current draw e Incomplete magnetic circuit due to the omission of parts such as coil housing coil sleeves coil spring coil housing bottom plate or plunger on the MKC molded model coils f Mechanical interference with plunger movement which may be caused by a deformed enclosing tube g Voltage spike h Valve ambient exceeds 120 F i Fluid or gas temperatures greater than 240 F while the valve ambient is 120 F Failure To Open Normally Closed Types a Coil burned out or an open circuit to coil connections
