Solenoid Control Valve

Installation, Operating and Maintenance Instructions

DESCRIPTION:

Model 106/206-SC is a globe or angle pattern valve
designed for two position (open or closed) operation.

The position of Main Valve (1) is selected electrically
by energizing or de-energizing Solenoid Valve (5).
These valves are available as Normally Closed (NC)
models, which close when the solenoid is de­energized or as Normally Open (NO) models, which
open when the solenoid is de-energized.

DESCRIPTION OF OPERATION:

Main Valve (1) closes when the inlet pressure is
directed to the bonnet and opens when the bonnet is
vented to downstream. Refer to 106/206-PG
"Description of Operation". Solenoid Valve (5)
connects the bonnet to upstream or downstream, as
required.

Opening Speed Control (6) limits the rate of flow from
the bonnet to downstream. Closing Speed Control (4)
limits the rate of flow from the upstream to the
bonnet. Note that Speed Controls (5) and (6) are
optional on 3” and smaller valves and standard on 4”
and larger. If the valve is not equipped with Speed
Controls, the rate of opening and closing is fixed and
can not be adjusted.

All valves include Strainer (3). Isolating Valves (2A),
(2B) and (2C) are optional on 3” and smaller valves.
They are standard on 4” and larger.

INSTALLATION:

1. Refer to 106/206-PG "Installation".

2. Check Solenoid Valve (5) name plate for correct
pressure. Check voltage at the side of the coil
(not the name plate).

3. Connect a suitable power source to the solenoid.
Refer to solenoid valve instructions. Never

energize an A.C. coil when the coil is removed
from the solenoid valve; the coil will be
destroyed in a matter of seconds.

ADJUSTING PROCEDURE:

If your valve is equipped with Speed Controls you can
adjust the opening and closing speed. Turn
appropriate Speed Control clockwise for reduced
speed; counterclockwise for increased speed. DO
NOT fully close either of the speed controls, or the
valve will not operate.

SERVICE SUGGESTIONS:

1. See service suggestions for 106/206-PG and
Solenoid Valve.

2. To reduce pressure drop on low flows, the
exhaust of Solenoid Valve (6) can be piped to
drain rather than downstream (provided that there
is 5 psi or higher pressure in the downstream).

3. NEVER ENERGIZE AN AC SOLENOID COIL

WHEN THE COIL IS REMOVED FROM THE
SOLENOID VALVE.
