SOLENOID VALVES

August 2003 / BULLETIN 30-11

To insure peak performance, solenoid valves must be selected and
applied correctly; however, proper installation procedures are equally
important. The following instructions list the essential points for
correct installation.

An exploded view of a typical solenoid valve is illustrated in Figures
5, 5A and 6, page 4.

Position

— All standard solenoid valves may be mounted

horizontal, on its side or in a vertical line with the exception of the
following: A3 dated 6-86 or before, MA32, B33, OB33, MA42,
MA50, MA5A, MA17A, XWG, XUP, XRN, XRM and XPO series.
These valves

MUST

be installed in horizontal lines with the coil

housing no more than 45° from vertical, see table on page 2. The
direction of flow is indicated by an

arrow

or the word

on the inlet

of the valve body. For heat pump applications, valve types C(M)E
and C(M)B are typically installed with the directional arrow pointing
toward the outdoor coil. Or, the

connection toward the indoor coil.

NOTE:

Solenoid valves having a type number starting with the letter

"X" are Special Solenoid Valves (non-standard). Contact Sporlan
Valve Company, Washington, MO if valve mounting is in question.

SOLDER CONNECTIONS

Because of possible damage to valve components due to the high
temperatures of soldering and brazing, "B" Series Solenoid Valves
with brass connections are shipped handtight to facilitate
disassembly, with the exception of the (M)B33S2 & OB33S2. It is
necessary to completely disassemble these valves before any heat is
applied to the valve body. The following steps outline recommended
procedures when installing these valves.

Soldering Precautions

— Solder connections on Sporlan Solenoid

Valves are either copper or brass. Any of the commonly used types of
solder are satisfactory with these materials. Regardless of the type of
solder used, it is important to avoid overheating the valve.

The tip of the soldering torch should be large enough to avoid
prolonged heating of the connection during the soldering operation.
Overheating can also be minimized by directing the flame away from
the valve body.

Type A3S1, S4S1, S6S1, S7S1

1. Remove the coil assembly.
2. Locate the word

or the directional

arrow

on the valve body.

3. Place the valve in the line, in the proper direction of flow, and

solder.

4. Replace the coil assembly and tighten coil hex screw.

Types B6, B9, B10, B14, B19, B25 Series (Brass Connections)

1. Remove the coil assembly, enclosing tube and nut, all internal

parts, and manual lift stem assembly.

2. Locate the word

or the directional

arrow

on the valve body.

3. Place the valve in the line in the proper direction of flow and

solder.

4. Re-assemble as follows, see Figures 1, 5, and 5A:

a. Place the seat disc into the valve body with the smaller

diameter end facing up.

b. Place the enclosing tube gasket onto the valve body above the

threads.

c. Hold the plunger with one hand so that the pointed end is

resting in the pilot port of the disk. Make sure the small spring
is in place on the top of the plunger.

(NOTE: Does not

apply to normally open and rapid cycle series.)

d. With the other hand, place the enclosing tube over the plunger,

making sure the enclosing tube gasket is in position.

e. Replace the enclosing tube locknut and tighten. (See

recommended torque in the table on page 2.)

Do not over

tighten.

f. Replace manual lift stem. Tighten lift stem assembly and seal cap.
g. Replace the coil assembly.

(NOTE: For normally open and

rapid cycle valves replace spacer and spacer cup
with coil assembly.)

NOTE:

Excessive tightening of the enclosing tube locknut can

damage the valve body bore. Please observe the torques listed on
page 2.

Types: All E Series (Extended Copper Connections)

Brazed into the line without disassembly because the valve contains
extended connections. Use caution by placing a wet cloth or chill
block on the extensions at the body to prevent excessive overheating.
Follow Type A3S1 installation instructions.
