REMARKS
1)
Solenoid Valve in which media passing through the valve is
Gaseous
and Orifice less than 25mm,
PED is not applicable.
2)
Solenoid Valve in which media passing through the valve is
Liquid Hazardous
nature, pressure 0.5
bar and
Liquid Non-Hazardous
nature, pressure below 10 bar, PEF is not applicable.
ELECTRICAL
1.
Verify name plate affixed on the Solenoid.
2.
For AC Voltage (50Hz or 60Hz), select solenoid with option “FR”
.
3.
Connect the power supply as per the voltage rating of the Solenoid.
4.
Ensure that the cover of Junction Box/Terminal Box is properly tightened wherever applicable.
5.
Install valve in such a way that the rain water / other process fluid dripping along the cable does not fall on the
SOV and has no possibility to run along the cable and enter into the Terminal area.
6.
Fill in the space between cable and gland entry with a proper sealant. If necessary, you may mount the valve
upside down or in any other direction.
7.
Ensure that the Solenoid enclosure meets process and local authority requirement.
8.
The Plug In, Terminal Box, FPJB are provided with test leads. Remove them before final installation.
9.
Check for proper connections for the Solenoid which are polarity sensitive e.g. (a) Latched Solenoid.
10.
Refer separate manual for construction of the Solenoid and for specific instructions related to
Solenoid e.g. (a) Latched Solenoid (b) Exd Solenoid IP 67
11.
Ensure that the solenoid construction is selected properly meeting the environment in which the valve is
supposed to be installed e.g. use of Ex d solenoid for valve to be installed in hazardous location or
Weatherproof Solenoid having IP 67 for outdoor installation.
12.
Flying Lead Solenoid is not recommended to be used for outdoor or indoor application where
water/liquid splashing or high humidity is present.
13.
Intrinsically Safe Solenoid can not be supplied with the Valve (Except 30308-5, 30334-5, 30333-5)
MANUAL OVERRIDE OPERATION
– OPTIONALLY PROVIDED
(A)
PUSH & TURN TYPE (M6)
When the solenoid is de-energized and inlet and outlet ports connected to the applying rated pressure, the
valve can be operated either pressing the Manual Override, when the same is released, the valve returns to
the normal position. The valve can also be locked in energized position by pushing the Manual Override and
rotating clockwise. To avoid Manual Override returning to normal condition, ensure that the same is turned
above 90º. The valve can be brought to normal condition by turning Manual Override anti clockwise.
(B)
PUSH TYPE (M8)
When the solenoid is de-energized, inlet and outlet ports connection and rated pressure applied, the valve
can be brought to energized position by pressing Manual Override / Lever. The valve remains in this position
till Manual Override / Lever is pressed. As soon as the same is released, the valve returns to the normal
position.
TESTING OF THE VALVE AT THE TEST BENCH
Check at least once in 3 years or following your routine maintenance schedule.
a)
Apply rated pressure at inlet port of the valve.
b)
Plug outlet port.
c)
Check operation of the valve and leakage at the exhaust port at the rated and minimum working pressure by
applying 75% to 120% rated voltage.
d)
While keeping the solenoid de-energized, check operation and leakage from exhaust of the valve at the rated
and minimum working pressure by operating Manual Override.
e)
Without connecting air supply to the valve, operate Manual Override. Energize and De-energize Solenoid to
check for the plunger movement (normally movement should not be there) which can be checked by click
sound. After operating Manual Override if plunger movement is found, reduce length of the manual override
by 0.3mm from its taper end. Continue this till click sound stops.
f)
Check the insulation resistance of the Solenoid by applying 500V DC at terminals and the solenoid housing. It
should be more than 100 Mega Ohms.
