REPLACEMENT PARTS AND PARTS KITS
① The pilot valve is available with or without the solenoid stop valve. The solenoid stop valve is not available separately and should not be removed from the pilot regulator.
② This part may be necessary to adapt a new pilot to some obsolete valves.
③ Replacement (S)ORIT-12 internal parts are only compatible with the Y1005 and Y1010 pilot valves. When using these parts with obsolete pilot valves, the pilot valve must also be replaced.
With the expansion valve at the Sporlan factory setting, or
at a manufacturer's predetermined setpoint, and under the
actual minimum load condition, the evaporator pressure
regulating valve should be adjusted to the desired setting.
Finally, if necessary, the thermostatic expansion valve or
valves can be adjusted to the desired superheat setting
while under the normal operating load condition.
When an evaporator pressure regulating valve has been
operating for a period of time at a given setting and an
increase in the setting is required, as much as 30 minutes
may be required for the new balance to take place after an
adjustment is made. If the valve is being adjusted to a lower
setting, an immediate response to an adjustment should be
observed.
To adjust the (S)ORIT valves, turn the adjustment screw
with a 3/8" hex wrench. A clockwise rotation increases the
valve setting, while a counterclockwise rotation decreases
the setting. To obtain the desired setting, a pressure gauge
should be utilized on the inlet side of the valve so the effects
of any adjustments can be observed.
When (S)ORITs are installed in parallel, each should be
adjusted the same amount to obtain optimum performance.
If one valve has been adjusted more than the other, both
valves should be adjusted all the way in before resetting
them an equal amount.
The (S)ORIT-12, -15 and -20 can be easily disassembled for
inspection and cleaning, or for replacement of the pilot
assembly. The pilot assembly is available with (Kit number
K-Y1005) or without (Kit number K-Y1010) the solenoid
stop valve. The solenoid stop valve is not available sep-
arately and should not be removed from the pilot reg-
ulator, nor should a standard solenoid valve be added
to the pilot assembly to achieve the stop feature. The
pilot port is critically sized with an orifice in the outlet of the
pilot assembly. The pilot kits contain: 1 pilot assembly; 2
gaskets (tetraseal for (S)ORIT-12 and -15; composition gas-
ket for (S)ORIT-20), and 1 copper flare gasket for the
(S)ORIT-20.
CAUTION: The pilot assembly should be isolated from the
high pressure power source before removal, and the main
valve body should be isolated from inlet and outlet pressures.
The (S)ORIT-12, -15 and -20 are normally open and by closing
off the pilot supply pressure (closing pressure), the (S)ORIT
main piston will shift to the full open position.
