Electric Remote Control Valve w/ Closing Speed Needle & 3-Way Solenoid- N.C Main Valve
DESCRIPTION
Model 410-01-3NC-200 Electrical Remote Control Valve is
designed to open and close drip-tight in response to an electrical
signal. The valve operates via upper control chamber on a 3-way
control principle. When the 3-way normally open solenoid 15 is
energized, the solenoid vents pressure from the control chamber to
atmosphere to open the main valve wide. When solenoid 15 is de-
energized, the solenoid applies upstream pressure to the control
chamber, via closing speed needle 5, to close the main valve drip-
tight. In addition, the valve comes with a manual operator to
manually open or close the main valve regardless of solenoid
position.
INSTALLATION
1. Allow enough room around the valve assembly for
making adjustments and for future maintenance and
disassembly work.
2. Thoroughly flush the pipeline to remove dirt, scale, and
debris. Failure to perform this operation may render the
valve inoperable.
3. It is recommended that isolation gate valves be installed
upstream and downstream of the Bermad control valve to
allow for future maintenance operations.
4. Install the valve in the pipeline with the valve flow arrow
on the body casting in the proper direction. Use the lifting
eye provided on the main valve cover for raising and lower
the valve. Install the valve horizontally with the cover up for
best performance. Make certain the valve is positioned so
the actuator assembly can be easily removed for future
maintenance requirements.
5. After installation carefully inspect/correct any damaged
accessories, piping, tubing, or fittings. Tighten all fittings.
IN LINE STATIC TEST PROCEDURES
OPEN VALVE STATIC TEST
1. Energize solenoid 15. If power supply is not available
to energize solenoid 15, turn manual operator 0 (black
handle) on solenoid base fully clockwise towards the “O” CW
marked on the solenoid base.
2. Caution: This will allow the valve to fully open. Make
sure this condition wll not cause system damage!
3. Check for leaks at the flange connection, fittings, etc.
CLOSED VALVE STATIC TEST (OPEN NEEDLE 5 OUT CCW)
1. De-energize Solenoid 15 or turn manual operator 0 (black
handle) on solenoid base fully counter-clockwise towards the
“O” marked on the solenoid base.
2. Open upstream gate valve (if applicable), allowing the
valve to close tightly.
3. Check the valve cover and diaphragm area for leaks.
Tighten cover bolts/nuts/fittings if necessary.
START-UP OPERATION
WIRING: Check the solenoid markings on the side of the coil to
verify proper voltage/wattage of coil (i.e 24 AC 3.5 Watt). This is to
prevent coil burn-out/inoperative solenoid. Verify solenoid
connections. There are 2 wires. One wire is power or ’hot’ and the
other wire is common (negative on DC systems). Polarity is not
important. Solenoid voltage at splice (not controller) must be at least
85% of the stamped voltage to function properly. Use safety
precautions.
NOTE: There must be flow through the valve and system to check
and adjust the valve. Insure that a downstream demand is created.
Verify solenoid electrical connections and voltage requirements.
Manual override knob 0 must be in the middle detent position
and neither turned CW or CCW for automatic clock/controller
command operation. Needle valve 5 must be open at least 1-2
turns out counter-clockwise -CCW from the closed position.
1. Open system gate valves if applicable.
2. Make sure manual operator 0 (black toggle on solenoid base)
is set in its middle detent position.
3. Energize solenoid 15 and valve will open. De-energize solenoid
15 and valve will shut drip-tight.
4. Adjust needle 5 in clockwise to increase closing time or counter-
clockwise to decrease closing time.
