ID Header = (NW2n)
n = Number of Valves operating at a time and which are connected to a common header,
NW = Orifice of the Valve.
g) Incorporate filter in the line to avoid hard particles entering into the valve.
h) The valve should be installed for the media for which it is intended for. This is to avoid the malfunction of
seals and the valve. In case if you intend to use valve for media other than the one specified on that
valve, check compatibility of media to Body Seal material and grease. Consult ROTEX in case if any
doubt.
i) Do not try to drill any additional holes or machine, modify any of the valve components.
j) In case if the valve is used for dangerous fluid gas/liquid then, the user is hereby advised to maintain
during operation and maintenance of the valve below LEL or above UEL to avoid explosion due to
internal spark as the valves have not been assessed for the same.
k) Inlet pressure does not exceed rated pressure.
l) Hemp-Filaments, ’Jute’ or even Teflon-Ribbons are normally not required, as the port connections of
ROTEX Valve is accurately machined.
m) To avoid over lap of the Teflon ribbon or cuts generated while tightening, getting carried away into the
valve. Do not cover first two thread pitches with Teflon tape or sealant.
n) For Solenoid Valve to be installed in European Union, check the applicability for ATEX. Refer
separate Instruction Manual for ATEX approved Solenoid Valve.
2. Provide Dust Cap on the exhaust port or ensure that the valve is mounted such a way that dust particles / rain
water / process fluid do not enter into the valve through exhaust port of the valve. You can connect bend pipe of
ID > NW of the valve so that the exhaust port is not directly (straight) open into the atmosphere.
3. The process fluid etc.: do not fall on the valve body.
4. In case if the surrounding atmosphere has traces or some other substance other than Air, check its compatibility
with the Body material of the valve, Solenoid enclosure & other exposed parts.
5. In case if the valve is installed in potentially hazardous area, check for the temperature class of the Solenoid to
avoid explosion due to heated Solenoid / other components.
6. Provide fuse of proper rating to avoid excess current passing through the Solenoid and thereby avoiding over
heating.
7. It is not likely however; the user is advised to protect the valve against lightening as the same is not assessed.
8. Check internal components (wetted) parts for its compatibility with fluid passing through the valve.
9. It is recommended to replace all the Rubber Parts including Plunger Assembly (Repair Kit ) in case if the
valve is to be installed and put in service after 2 years from the date of manufacture.
10. Connect Port-2 to activate port of Rotary Actuator / Cylinder / Control Valve.
11. In case if Actuator does not open / close when the valve is operated electrically / manually, verify the correct
mounting of the valve probably Port-2 of the Solenoid Valve may not even match to the active port of Actuator /
Control Valve. After disconnecting the air, open the valve and re fix the same after turning 180º.
12. To prevent accidental wrong fixing of the valve, the solenoid valve is provided with M5 x 10mm long Grub Screw
(supplied loose), fix the same on one of the spare hole of the Actuator / Control Valve keeping 2-3mm projection
and matching the location at which the counter hole in the solenoid valve body. After this, in case tries of fixing
the valve in other direction, the same will not fit well.
ELECTRICAL
1. Verify marking affixed on the Solenoid.
2. For AC Voltage (50Hz or 60Hz), select solenoid with option “FR”.
3. Connect the power supply according to 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, IS Solenoids 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) EExd 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 Exd 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.
