Epoxy Coating - suffix KC
An FDA approved fusion bonded epoxy
coating 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 C550-90. 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
operation. 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
recommended for valves in continuous
operation where differential pressures are
in excess of 80 psi (2" and larger Hytrol valves).
Water Treatment Clearance - suffix KW
This additional clearance is beneficial in
applications where water treatment
compounds 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.
Viton
®
Rubber Parts - suffix KB
Optional diaphragm, disc and o-ring
fabricated 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.
Heavy Spring - suffix KH
The heavy spring option is used in
applications where there is low differential
pressure 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.
