INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
1 Introduction
1.1 Scope of the Manual.
The purpose of this manual is to ensure that the valves supplied are properly installed and maintained to give trouble free performance
.
This manual covers FNW single piece body bu valves from 2” to 72” in both wafer, lug and double
anged designs.
1.4 Marking.
Speci cations of the valve are marked on the body or on name plate or both, prior to shipment. The identi marking generally consists of size of valve, pressure rating body material, trim material, serial number and the manufacturing date.
1.2 General Design.
The FNW Butter y valves are tight shu with wafer or lugged body construction. The valves

standards
The valves are bi-directional. The valve
seat enveloping the entire wetted surface and the
ange contact face of the body.
1.3 Flange and Pipe compatibility :-
Butter y valves are designed to t between schedule 40 (for class 150) & schedule 80 (for class 300) & above 100 (for class 600) pipe, and the following pipe

INSTALLATION, OPERATION & MAINTENANE INSTRUCTIONS
3 Safety Precautions.
3.1 Do not exceed the valve pressure / temperature rating limitations!
Exceeding the pressure/temperature rating limitations marked on the valve may result in major damage or Personal injury. Users of these valves should ensure that the valve pressure / temperature is less than or equal to the rated pressure/temperatures. If required, end user should incorporate appropr the system for the safe operation of the valve.
3.2 Use the valve for speci ed application only!
iate limiting/monitoring devices in
User to ensure that the valve is used only for the speci
ed application as agreed between the
manufacturer and the purchaser.
3.3 Follow the safety rules and regulations!
User of the valve must be aware of all the safety rules and regulations related to a particular environment in which the valve is to be used.
4 Transportation, Receiving and Storage.
4.1
Valves are being packed in cartons, boxes or pallets while shipping to the customer. Care should be taken to store them in a suitable place. We recommend storing the valves indoors in a dry and dust free atmosphere (Refer to that the valves and any other accessories have not been damaged during transportation. Avoid mechanical damage to the valve seat during storage. Rubber lined valve must not be stored for more than 2 years without installation, unless speci
gure 2.1). W hile unpacking the valves, check
ed otherwise.
3.4 Do not disassemble the valve or remove it from the pipeline while the valve is pressurized!
Disassembling or removing a pressurized valve will result in uncontrolled pressure release. Always isolate the relevant part of the pipeline, release the pressure from the valve and remove the media before dismantling the valve.
Be aware of the type of media involved. Protect people and the environment from any harmful or poisonous substances.
Make sure that no dust, dirt can enter the pipeline during the valve maintenance
.
3.5 When handling the valve or the valve package, bear in mind its weight!
Never lift the valve or valve package by the handle , gear operator, actuator or hand wheel. Place the rope securely around the valve body while handling the valve. Refer to Fig No. 1.2
Fig 2.1 Storing the Valve.
• Caution:
Placing the valves directly on the ground or on a
concrete
oor should be avoided!
All wrapping and protection on the valves should not be

removed until the valve is ready for installation.
4.3
If the valves are stored for a long time, then all the valves should be cleaned and hydro / pneumatic tested before installation. Refer to General Arrangement drawing, which lists the appropriate testing standards, or consult the nearest branch o
ce / factory for more information
Valves are bi-directional and can be installed in either

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
5.2 Valve open or close position is indicated on the notch
5.0 Installation
5.1 When removing the valve from storage a careful
check should be made to ensure that the valve has not been damaged during the storage period.
5.5 Valve should be checked for identication purp ose and ensure that characteristics of valve matches to tho se specied for piping specications, for the line w here that is to be mounted. Nameplate instructions will give the
plate for lever operated valves or on the top of the gear operator for gear operator operated valves
necessary information.
5.3 Center valve, span body with bolts, but do not tighten. Slowly open disc to ensure that it clears adjacent pipe ID and leave at full open position. Tighten bolts in a cris cross pattern refer g 3.5.

Note:
a)
Do not attempt to correct the line misalignment by means of ange bolting Ref to g 3.3. b) Use ange gaskets Ref to g 3.4. c) Valves shall never be mounted with the operator vertically downwards.
5.7 Recommended Bolt Tightening Sequence:
Place the valve between the anges, center it and then span the valve body with all ange bolts, but do not tighten the bolts. Carefully open the disc to the full open position, making sure the disc does not hit the adjacent pipe I.D. Now systematically remove jack bolts or other ange spreaders, and hand-tighten the ange bolts as shown in g.3.5 Very slowly close the valve disc to ensure disc edge cl
earance from adjacent pipe ange I.D. Now open the disc to full open and tighten all anges bolts as per specication as shown in g. Finally, repeat a full close to full open rotation of the disc to ensure proper clearance.

5.8 Insulation / lagging of the valve and pipeline outside diameter is recommended, where uid temperatures are going to be higher than 150
It is recommended to use ASTM A193 Gr.B7 fasteners for ange bolting.
