KEYSTONE PED - OPERATING AND SAFETY INSTRUCTIONS
RMI ButteRfly ValVes
Before installation, these instructions must be fully read and understood
HAZARD POTENTIALS
• disregarding of instructions
• improper use of product
• insufficiently qualified personnel
Ensure that valve materials are compatible with
the pipeline fluid.
Pressure/temperature limits indicated in the
P/T diagram of the Product Manual.
If in doubt contact factory.
Check the valve’s functionality on a regular basis.
PRECAUTIONS
WARNING
For safety reasons, it is important to take the
following precautions before you start work on
the valve:
1. Personnel making any adjustments to the
valve should utilize suitable equipment.
All required personal protection means should
be worn.
2. The line must be depressurized before
installing the valve. In case of dangerous
pipeline fluids, the pipeline should be drained
and flushed properly with an appropriate
cleaning fluid.
Material identification Unidirectional or
Type of valve
Bidirectional
Size
3. Personnel trained in all aspects of manual and
mechanical handling techniques must carry
out handling of all valves.
4. Do not use the valve beyond specification.
The valve, handle, actuator and other parts
may not be used as “climbing tools”.
5. Ensure the valve pressure/temperature
specification as indicated on the identification
label is within the pressure/temperature limits
of the application. A full pressure/temperature
diagram can be obtained from the Product
Manual. With the use of the figure and trim
number on the valve’s identification label,
thecorrect diagram can be found.
INSTALLATION
1. Handling and lifting should be performed
according the Maintenance and Installation
Instructions.
2. Keystone valves are bi-directional unless
fitted with a flow direction arrow. If a
directional arrow is fitted then the valve
must be installed with the arrow pointing in
the direction of the flow.
3. For detailed installation instructions
refer to the Maintenance and Installation
Instructions for the specific product.
4. Preferred installation position of butterfly
valves is the shaft horizontal and the lower
disc-edge opening downstream.
5. Do not use the valve to spread the flanges.
6. Instructions whether to use or to
omit flange gaskets are stated in the
Maintenance and Installation Instructions.
7. In case the valve is used as spool piece
during erection of piping, do not finish weld
the flanges to the pipes with the valve bolted
between the flanges as this will result in
serious heat-damage to the seat.
8. Valve operation should be checked for
open - close positions. The disc should have
enough clearance from the pipeline in all
positions.

!! Read all warning labels fitted to the valve
before operation or maintenance !!
MAINTENANCE
Check the valve’s functionality on a regular
basis. No additional routine maintenance is
required.
REPAIR
WARNING
The line must be depressurized before carrying
out any repairs to the valve. In case of dangerous
pipeline fluids, the pipeline should be drained and
flushed with an appropriate cleaning fluid. Failure
to do so may cause serious personal injury and/or
equipment damage. Before disassembling the
valve ensure the valve has been decontaminated
correctly from any harmful gasses or liquids
and that it is within a safe temperature range for
handling. Personnel making any adjustments
to the valves should utilize suitable equipment.
All required personal protection means should
be worn. Only qualified personnel trained in all
aspects of manual and mechanical handling
techniques must carry out lifting and handling of
valves.
Use Keystone original spare parts only.
For detailed information on valve (dis)
assembly and part replacement, refer to the
Maintenance and Installation Instructions.
