IV. INSTALLATION
A. Orientation:
1. Standard orientation is with the yoke with
position indicator plate and valve body outlet
port in same plane. If an alternate ar range-
ment is necessary, loosen yoke nut (8)
se cur ing yoke (3) to bonnet (2) ap prox i mate ly
three revolutions. Rotate actuator assembly
(AA) to de sired po si tion with re spect to body
as sem bly (BA). Re-tighten yoke nut (8) to 85
ft-# (115 N M). NOTE: This pro ce dure can
be done in-line.
2. Valve body must be installed in a horizontal
or vertical plane where the outlet connection
fl ow direction is down wards or horizontal (see
Figure 1). Failure to comply will cause the
self-draining of the internal passages to be
nullifi ed, allowing CIP clean ing/fl ushing fl uids
to be ponded.
A. Clean-in-Place (CIP):
1. Control valve unit must be properly oriented
per Sec tion IV.A. to assure self-draining of
valve’s internal pas sag es.
2. Control valve unit comes in the direct action,
ATC-FO arrangement or the reverse action,
ATO-FC ar range ment. Valve should be in
the full open po si tion before initiation of the
CIP pro ce dure. Control system must ac com-
mo date this ca pa bil i ty.
3. Cleaning
fl uid may fl ow in either direction.
4. Cleaning
fl uid pressure must not exceed 60
psig (4.1 Barg).
5. Cleaning
fl uid temperature must not exceed
300°F (149°C).
6. Cleaning
fl uid must be compatible with wetted
ma te ri als.
III. OPERATION CONSIDERATIONS
B. Steam-in-Place (SIP):
1. Orientation to be same as CIP,Section III.A.1.
2. Steam
may
fl ow from either direction.
3. Recommended 20 psig @ SAT (1.4 Barg @
SAT). Maximum 30 psig @ SAT (2.1 Barg
@ SAT).Valve must be in the full open during
the SIP pro ce dure.
C. Hose-Down Cleaning:
1. Standard Model SCV-30 control valve units
supplied with I/P positioners are NOT de signed
to allow hose-down wash ing of the unit’s ex-
te ri or.
D. Instrument Air Supply - IAS:
1. For Model SCV-30 with a positioner rec om-
mend using cryogenically pro duced nitrogen
gas, or oil-free com pressed air des ic cant
dried to -40°F(-40°C) dew point, fi l tered to 10
mi crons or less as the IAS source.
2. All exhaust/vent air utilized by the Model
SCV-S unit enters the ambient en vi ron ment.
