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.
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.
ELECTRICAL
1. Verify name plate affixed on the Solenoid.
2. Connect the power supply according to the voltage rating of the Solenoid
3. Ensure that the cover of Junction Box/Terminal Box is properly tightened wherever applicable.
4. 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.
5. 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.
6. Ensure that the Solenoid enclosure meets process and local authority requirement.
7. The Plug In, Terminal Box, FPJB, IS Solenoids are provided with test leads. Remove them before final
installation.
8. Check for proper connections for the Solenoid which are polarity sensitive e.g. (a) Latched Solenoid (b) EEx ia
Solenoid.
9. Refer separate manual for construction of the Solenoid and for specific instructions related to Solenoid e.g. (a)
EEx ia (b) Latched Solenoid (c) EExd Solenoid IP 67,IP 54
10. 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 or Ex ia solenoid for valve to be installed in hazardous location or
Weatherproof Solenoid having IP 67 for outdoor installation.
11. Flying Lead Solenoid is not recommended to be used for outdoor or indoor application where water/liquid
splashing or high humidity is present.
RECOMMENDED SPARES
a) O Ring Set.
b) Plunger assembly (Part No. 30).
c) Spare Solenoid.
SPECIAL TOOLS
• Guide Opening Tool : ROTEX Ref No. WN 1219 / M28 (Photo-1) or WN1219 / M22 (Photo-2) (ROTEX make).
(B) TO REPLACE GUIDE ASSEMBLY (CORE TUBE) (Part 33) / PLUNGER (Part 30)
1) Open Dome Nut (Part 37) and pull out solenoid (Part 34).
2) Open Guide Assembly (Core Tube) (Part 33) using guide opening tool as per Photo - 2 or 3 (depending
on the Guide Assembly (Core Tube) fitted on the valve).
3) Remove Plunger Assembly (Part 30).
4) Replace the necessary defective parts ensuring that the plunger assembly spring and the retaining ring
is as per Photo - 5 or as per Photo – 6 & 7.
5) The Plunger as per Photo - 6 & 7 is interchangeable and can be fitted in the existing Guide Assembly
(Core Tube).
6) Fix Guide Assembly (Core Tube) using correct tool.
7) Fix the solenoid and Dome Nut as per Point-4 of procedure A.
8) Eventhough it is not recommended, in case if required, the Guide Assembly (Core Tube) (Part 33) can
be opened using plier or other similar tool ensuring that the same does not damage anything or
component and the plier is tighten above weld joint (weld joint should be at the centre of plier jaw width).
(C) REPLACEMENT OF MANUAL OVERRIDE (PART 8)
1) Remove Grub Hex.Socket Set Screw (Part 115) and pull out Manual Override (Part 8).
2) Replace new Manual Override applying light layer of Silicon Grease Molykot M55 and tighten the grub
screw fully till the Manual Override stops traveling in and out.
3) Open the Grub Hex.Socket Set Screw slightly (1/4 turn) and check the smooth movement of the Grub
Hex.Socket Set Screw.
4) Without connecting air supply to the valve, operate Manual Override. Energise and De-eneerigse
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 tapper end. Continue this till click sound stops.
(D) REPLACEMENT OF O RINGS
1) Remove solenoid if necessary as per Procedure (A).
2) Remove Deckel (Cover) (Part 2) by opening four screws.
3) Remove Ventilboden (Valve Bottom) (Part 3) using internal circlip plier.
4) Remove Ventilfeder (Valve Spring) (Part 16).
5) Open Nut (Part 12).
6) Insert rod in hole provide in Ventilschaft (Valve Shaft) (Part 5) to remove Nut (Part 12).
7) Remove all the “O” Rings [Piston O Ring (Part 18 – 1 No.), Seat O Ring (Part 19-2 Nos.), Body O Ring
(Part 20 – 2 Nos.)].
8) Clean components.
9) Fix new O Rings applying light layer of Molykot M55 grease.
10) Ensure that the O Rings and other rubber parts are compatible to the media passing through the valve.
11) Reassemble the valve.
12) Check operation and leakage of the valve
13) Contact ROTEX in case of any difficulty.
