KEYSTONE HILOK HIGH PERFORMANCE BUTTERFLY VALVE
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Before installation these instructions must be fully read and understood
1 GENERAL INFORMATION ON THE
INSTALLATION AND MAINTENANCE
INSTRUCTIONS
These installation and maintenance
instructions contain the information necessary
for safe and correct installation and operation
of the fitting. If any difficulties are encountered
during installation or operation which cannot
be solved with the aid of the installation and
maintenance instructions, please contact the
supplier/manufacturer for more information.
These installation and maintenance
instructions comply with the relevant applicable
EN safety standards. When installing the fitting,
the operator or the person responsible for
thedesign of the installation must ensure that
applicable national regulations are complied
with. The manufacturer reserves all rights to
make technical changes and improvements at
any time. We recommend that all maintenance,
installation and operation personnel will
understand these instructions, which are
accessible via

2 SAFETY
Please also read through these notes carefully.
2.1 General potential danger due to:
a. Failure to observe the instructions
b. Improper use
c. Insufficiently qualified personnel
2.2 Correct use
2.2.1 Area of application
HiLok valves are valves that are used for the
isolation, throttling and regulation liquids,
together with gases, pastes and powdery
products in pipelines, vessels, apparatus etc.
The area of use of the fitting is the responsibility
of the system designer. Special characteristics
of the fitting must be taken into account.
A very wide selection of product-wetted
components parts is available which allows
suitable combination for the optimal solution
to your specific application. Always consult
themanufacturer when the fitting is to be used
with media that require or preclude the use of
certain materials.
2.2.2 Method of operation
The valve is opened or closed by turning the
valve spindle. The angle of rotation is 90°.
2.2.3 Performance data
Pressure range: see table
Temperature range: see table
Nominal diameter range: DN 50 - 900
Test pressure: 1.5 x PN
2.2.4 Usage restrictions
The product-wetted components must be
classified as resistant to the product to be
conveyed. Refer to appropriate literature or
consult the manufacturer or distributor for
advice on this.
2.2.5 Modification prohibition
Mechanical modifications to the valves or
theuse of other manufacturers’ parts for repair
purposes are not permissible. Safety is not
guaranteed if this requirement is disregarded.
Repair work must only be carried out by
themanufacturer’s trained personnel.
2.2.6 Warning about foreseeable misuse
Valves and their accessories (e.g. operating
elements) must not be misused as climbing
aids.
2.2.7 Duty to comply with the instructions for
operation, maintenance and servicing
These instructions are part of the delivery
package and must be kept clean and made
accessible to the user.

3 TRANSPORT/STORAGE
The valve is supplied with protective covers.
Do not remove the protective covers until
immediately prior to installation.
3.1 Transport
• Transport temperature -20°C to +65°C
• Protect against external force (impact, shock,
vibration)
3.2 Storage
• Storage temperature -20°C to +65°C, dry and
dust-free
• A drying agent or heating is required in damp
storage areas to protect against condensation
• Keep the valve disc in a closed position
3.3 Handling prior to installation
• With versions with protective covers, only
remove the covers immediately prior to
installation!
• Protect against the effects of weather, such
as dampness (or else use a drying agent)
• Proper treatment prevents damage
2.3 Sources of danger
2.3.1 Mechanical
When using the hand lever, it should be
ensured that there is still sufficient clearance
for the hands at the end position of the
handle, so that there is no risk of trapping.
Excessiveoscillation and vibration should be
avoided, toprevent the bolts loosening.
2.3.2 Electrical
None for a bare shafted valve

2.3.3 Thermal
Due to the range of operating temperatures
between -50°C and +400°C, surface
temperatures from -20°C to over +400°C can be
present on the valve body. Suitable precautions
should be taken to protect against burns due
to high or freezing temperatures. In particular,
insulated gloves should be worn when using
the hand lever, for example.
