VGF FLANGED VALVES
63-2618 8
INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check ratings given in instructions and on the product to
ensure the product is suitable for your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
WARNING
Severe Burn Hazard.
Contact with hot liquid can lead to severe injury or
cause death.
Release system pressure and isolate or drain the
valve pipe section so the medium (steam, water or
glycol solution) does not leak out of the valve body
during installation (see Fig. 9).
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply to the actuator to prevent
electrical shock and equipment damage, or remove
and cap the air line to the actuator.
IMPORTANT
• Before installing the valve, raise and lower the valve
stem to make sure that the valve stem operates
freely. Impaired stem operation can indicate that the
stem was bent by rough handling. This condition can
require replacing the valve.
• Protect the stem from damage due to bending or
scratching.
Safety
The valves are to be installed by skilled personnel and in strict
accordance with the installation instructions and local
regulations. (See Fig. 8 for proper hoisting method.)
Honeywell assumes no responsibility for damages or injuries
resulting from non-compliance with installation instructions or
standard good practice when mounting, operating, or
maintaining the valves, even if not explicitly mentioned in the
installation instructions. (See Fig. 10 for basic pipe
orientation.) Observe all safety practices when working with
steam systems.
Proper Use
These valves are only for use in cold, warm, hot water
systems and for steam applications. They are designed for a
medium temperature range of from 35 to 355°F, at a
maximum pressure of 125 or 250 psig, depending on their
ANSI body class. They are to be operated with the
appropriate Honeywell actuators only. Water should be
properly filtered, treated and conditioned according to local
conditions. The installation of a strainer is strongly
recommended.
IMPORTANT
The presence of iron oxide (red rust) in the system
voids the valve warranty.
