2.5 adjuStMENt oF Shut-oFF ValVE FoR StEaM
Supply
– The built-in shut-off valve is equipped with an adjustment device (A) to
limit the steam flow rate. A special tool is necessary for
adjusting the valve-seat.
– The correct adjustment is very important particularly for higher pres-
sure, and therefore must be done by a HOBART trained service techni-
cian at first installation or after any changes are done at the customer
site.
– The adjustment is correct if the heating-up time of the boiler is as long
as the shortest wash cycle, while the valve is opened to maximum.
– If adjusted too far open pressure shocks may occur when the solenoid
valve closes. This could cause damage at the installa tion. If adjusted
too far close the required heating-power cannot be achieved.
