CA5 and SA5 - ULTRA HIGH PURITY, SPRING LOADED
I. DESCRIPTION AND SCOPE
Models CA5/SA5 are spring operated back pressure regulators used to control upstream (inlet or P1) pressure. Sizes are
3/4" (DN20) and 1" (DN25). With proper trim uti li za tion, the unit is suitable for liquid or gaseous service. (NOTE: This
product was formerly identified as a Model C5 or S5; a Model CA5/SA5 and C5/S5 are one and the same product.)
II. REFERENCES
Refer to Technical Bulletin CA5/SA5-TB for tech ni-
cal specifications of a Model CA5/SA5 reg u la tor.
III. INSTALLATION
1. Install per direction of flow arrow indicated on
body, or "IN" and "OUT" markings.
2. Regulator may be rotated around pipe axis 360
degrees. For ease of maintenance, the rec om-
mend ed orientation is with the spring chamber
(4) upwards.
3. Provide space below, above, and around reg u la tor
for removal of parts during maintenance.
4. Install block valves and pressure gauges to pro-
vide means for adjustment, operation, bypass, or
removal of the regulator. A UHP filter is rec om-
mend ed before inlet to remove typical pipe line
debris from entering valve and damaging internal
"soft goods", primarily the dynamic seal and valve
seat.
