INSTALLATION, OPERATING and
MAINTENANCE INSTRUCTIONS
SINCE - 1875
for KUNKLE SAFETY and RELIEF VALVES
Where safety valves require repair, service adjustments or set pressure change
with new spring, work shall be accomplished by the manufacturer, user, or holders
of "V", "UV" and/or "VR" stamps. However, proper installation, operation and
maintenance procedures will prevent many problems and permit you to obtain good
service from your Kunkle safety and relief valves.
INSTALLATION
1. Mount the valve in a vertical position so that discharge piping and Code
required drains can be properly piped to prevent build-up of back pressure
and accumulation of foreign material around the valve seat area.
2. Apply only a moderate amount of pipe compound to male threads only, leaving
the first thread clean. Compound applied to female threads or used to
excess can find its way into the valve, causing leakage.
3. Avoid over-tightening threaded connection valves as this can distort the
seats. As the valve and the vessel are heated, the heat involved will
grasp the valve more firmly.
4. When installing flange connected valves, use new gaskets and draw the
mounting bolts down evenly.
5. Do not use the valve outlet or cap as a lever for installation. Use only
flat jawed wrenches on the flats provided.
6. Arrange discharge piping (if used) so that it cannot bear on the valve when
either hot or cold, by using a drip pan elbow or flexible connection between
the valve and the escape pipe.
OPERATION
1. Avoid having the operating pressure too near the safety valve's set pressure.
A minimum differential of 5# or 10% (whichever is greater) is recommended.
An even greater differential is desirable and will assure better seat
tightness and valve longevity.
2. Avoid excessive operation of the safety valve as even one opening can provide
a means for leakage. Safety valves should be operated only often enough to
assure that they are in good working order.
3. Pop test the valve by raising the operating pressure to the set pressure of
the safety valve, allowing it to open and reseat as it would in normal service.
4. Do not hand operate the valve with less than 75% of the stamped set pressure
exerted on the underside of the disc. When hand operating, be sure to hold
the valve in an open position long enough to purge accumulated foreign materiel
from the seat area and then allow the valve to snap shut.
5. Avoid wire, cable or chain pulls for attachment to levers that do not allow
a vertical pull. The weight of these devices should not be directed to the
safety valve.
MAINTENANCE
1. DeveTop a regular program of visual inspection, looking for clogged drains
and discharge pipe, dirt build-up in and around the valve seat and broken
or missing parts.
2. Test the safety valve every two to six months (depending on plant age and
condition), preferably by raising the system pressure to the safety valve's
set pressure or operating the hand lever (see point 4 under "Operations" above).
3. Do not paint, oil or otherwise cover any interior or working parts of any
safety valve - safety valves do not require any lubrication or protective
coating to work properly.
