Construction Details Sporlan Solenoid Valves
Sporlan Solenoid Valves are constructed to ensure
long, trouble-free life. They employ proven design
features for reliable performance on all applications.
By using modern production equipment, Sporlan
consistently provides top quality solenoid valves for
air conditioning, refrigeration and other uses. Quality
is maintained by strict quality control methods in all
phases of production followed by detailed testing of
every valve produced.
Extensive use of stainless steel, thoroughly proven
synthetic materials and modern sealing methods along
with top grade brass, bronze and semi-steel body ma-
terials, contribute to Sporlan’s high quality product.
The table on Page 23 lists the materials and con-
struction details of Sporlan Solenoid Valves. Sporlan
reserves the right to change materials that improve the
quality, performance and/or integrity of the product.
Coil Construction
Sporlan solenoid coils are constructed with some of
the finest materials available for electromagnet coil
manufacture.
Standard Coils — The number 1 and 2 coils are
wound on a molded Rynite
®
bobbin. The wound bob-
bin is then inserted into a mold in a transfer press and
encapsulated with a thermoset polyester compound.
The coil yoke is assembled afterward and the coils are
identified as (O)MKC-1 and (O)MKC-2. The thermo-
set polyester is moisture proof, fungus proof and meets
military specifications.
Sporlan Solenoid Valve coils are available in many
voltage and cycle ratings. The standard coils required
are listed on the Specification pages for the various
valves. Dual voltage, direct current (DC) and other al-
ternating current (AC) coils are available for most valve
types at slight additional cost. For other voltages and
cycles, consult Sporlan, Washington, MO.
Color Coded Lead Wires — For ease of iden-
tification, coils are manufactured with the following
colored lead wires:
All other coils are supplied with black lead wires.
Wiring for Dual Voltage Coil
Leads on valves with a conduit boss are 18” long
while coil leads on valves with a junction box are 6”
in length.
Junction Box — All solenoid valves are avail-
able with either an integral junction box or a 1/2”
conduit connection at no extra charge. All valves are
automatically supplied with the integral junction box.
If a conduit boss is required, it must be specified on
the order.
All junction boxes are equipped with grounding screw
provisions and marked in accordance with UL and
CSA recommendations.
Conduit Boss — Nema Rating — The Standard
(O)MKC-1 and (O)MKC-2 coil assemblies with con-
duit boss type yokes will satisfy Nema 4 and IP55
(Rain Tight) as well as Nema 1, 2, 3, 3R, 3S, 12
and 13.
DIN Connector — (O)MKC-1E and (O)MKC-2E
coils with Female DIN Connectors will satisfy IP65.
Coil Interchangeability — Only two coil sizes are
required with the complete line of Sporlan Solenoid
Valves.
The molded MKC-1 coil will fit the old style KC-1
coil. The molded MKC-2 coil will fit the old style
KC-2 coil. Since the molded coils are a complete
magnetic assembly, the old housing and related parts
should be discarded when replacing the old KC-1 or
KC-2.
