Limitations
The correct selection of materials of construction, seats and seals, internal valve
components and pressure/temperature ratings determines the safe use of the valves and
the particular performance requirements for the application.
This information can be found on the name plate welded to the valve body.
The combined corrosion and erosion allowance for the valve body wall thickness is
1(mm). When this allowance has gone, the valve should no longer be used. Inspect the
valve wall thickness every time the valve is maintained.
Refer to Habonim Chemical Compatibility Chart to determine the corrosion rate for your
application.
As the variety of applications these valves can be used in is large, it is impossible to
cover all installation and maintenance instructions for servicing the valves.
Habonim's standard valves design is for relative humidity of 50% and SATP (Standard
Ambient Temperature and Pressure) environment conditions.
It is the o
wner’s
responsibility to use the valves as recommended and in accordance
with the pressure/temperature limits and chemical compatibility for both
inner &
outer
parts as stated in this manual.
Where in doubt, please consult with Habonim.
Any unstable fluid or gas should be identified by its manufacturer and must not be used
with Habonim valves.
CAUTION:
The valves should be used in a well-designed, adequately protected system to
ensure that external and internal pressure and temperature limits do not exceed the valve
limits.
The valve rating is defined as the lower rating of the seat and valve body.
Valve surface temperature may become extremely hot or cold due to operating conditions.
Prevent any type of direct contact with the valve that may cause harm or injury .Avoid direct
contact with the valve by wearing protective gloves.
The valves are not designed to operate during or after earthquakes or under fatigue conditions.
It is the responsibility of the owner to determine if fatigue conditions exist.
The process fluid temperature shall not exceed the ignition temperature of the dust.
WARNING:
USE OF THE VALVE IS APPLICATION SPECIFIC. BE SURE THAT THE VALVE IS SUITABLE
FOR ITS INTENDED SERVICE. IF YOU HAVE ANY QUESTIONS CONCERNING THE USE,
APPLICATION OR COMPATIBILITY OF THE VALVE WITH THE INTENDED SERVICE, CONTACT
HABONIM FOR MORE INFORMATION.
DO NOT EXCEED THE VALVE PERFORMANCE LIMITATIONS!
EXCEEDING THE PRESSURE OR TEMPERATURE LIMITATIONS MARKED
ON THE VALVE LABEL PLATE MAY CAUSE DAMAGE AND LEAD TO
UNCONTROLLED PRESSURE RELEASE. DAMAGE OR PERSONAL
INJURY MAY RESULT.
