Cla-Val 138-01/638-01 - Manual (Page 8)

Specifications Model 100-01
Viton ® Rubber Parts - suffix KB
Optional diaphragm, disc and o-ring fabri-
cated with Viton
® synthetic rubber. Viton ® is
well suited for use with mineral acids, salt
solutions, chlorinated hydrocarbons, and
petroleum oils; and is primarily used in high
temperature applications up to 250° F. Do
not use with epoxy coatings above 175° F.
Epoxy Coating - suffix KC
This option NSF 61 Listed and FDA
approved, fusion bonded epoxy coating is
for use with cast iron, ductile iron or steel
valves. This coating is resistant to various
water conditions, certain acids, chemicals,
solvents and alkalies. Epoxy coatings are
applied in accordance with AWWA coating
specifications C116-03.
Do not use with temperatures above 175° F.
Dura-Kleen® Stem - suffix KD
This stem is designed for applications
where water supplies containing dissolved
minerals create deposits that build-up on a
standard stem and hamper valve opera-
tion. A patented, self-cleaning design on
the stem allows all valve sizes to operate
freely in the harshest conditions.
Delrin ® Sleeved Stem - suffix KG
The Delrin ® sleeved stem is designed for
applications where water supplies contain
dissolved minerals which can form
deposits that build up on the valve stem
and hamper valve operation. Scale build-
up will not adhere to the Delrin
® sleeve
stem. Delrin ® sleeved stems are not rec-
ommended for valves in continuous opera-
tion where differential pressures are in
excess of 80 psi (2" and larger Hytrol valves).
Heavy Spring - suffix KH
The heavy spring option is used in applica-
tions where there is low differential pres-
sure across the valve, and the additional
spring force is needed to help the valve
close. This option is best suited for valves
used in on-off (non-modulating) service.
Anti-Cavitation Trim - suffix KO
Anti-Cavitation Trim components consist of
a stainless steel radial slotted disc guide
and seat. This system is used when high
differentials are present across the valve.
Water Treatment Clearance - suffix KW
This additional clearance is beneficial in
applications where water treatment com-
pounds can interfere with the closing of the
valve. The smaller outside diameter disc
guide provides more clearance between
the disc guide and the valve seat. This
option is best suited for valves used in on-
off (non-modulating) service.
