ADAPTER
Hexagonal-shaped brass, stainless steel or plated leadloy part which
attaches to stop port of all 2-way normally open and most 3-way
valves. The adapter enables the connection of the valve to any piping
system.
BUBBLETIGHT
A sealing capability within the valve which is undetectable during
a ten second soap bubble test; approx. = 2 x 10-3 cc/min of air.
CV
FACTOR
A value that indicates relative flow capacity of a valve. This value
is defined as gallons of water per minute (GPM) at 60°F, which will
flow through the valve with a pressure drop of one PSI.
COIL
VOLTAGE
The voltage at which the coil must be energized if the valve is
to perform as stated in the specifications. KIP coils are designed
to operate at +10% and -15% of their rated voltages.
CONTINUOUS
DUTY
A rating given a coil under normal operating conditions that can
be used continuously without overheating or failure. All standard
KIP valves are rated for continuous duty.
DE-ENERGIZED
No current is flowing through the coil. The return spring holds
the plunger against the body orifice. A normally closed valve is
de-energized in a closed position.
DIFFERENTIAL
PRESSURE
Pressure difference between the inlet line and the outlet line,
i.e. 100 PSI operating pressure on inlet minus 80 PSI back pressure
from outlet line = 20 PSI differential pressure.
ENERGIZED
Current is flowing through the coil. The magnetic flux resulting
from electricity passing through the coil forces the plunger to
pull against the end stop. When a normally closed valve is energized,
the valve opens and stays open until the electrical current stops.
HEAT
RISE
The difference between the temperature of the solenoid coil when
de-energized and energized. KIP's standard coils are Class B construction
(266°F/130°C. max). Ambient Temperature ± Heat Rise in Coil (KIP's
coils are typically at 90°C) = Total Temperature If the ambient
temperature is 70°C, the total temperature would be 160°C and the
application would require a Class H coil (180°C) instead of a Class
B coil.

INTERMITTENT
DUTY
A rating given to a coil whose heat rise is too high for continuous
duty. By using the coil with minimum 'ON' time, the coil will not
reach extreme temperatures that would cause the valve not to operate,
or fail prematurely.
MOPD
(Maximum Operating Pressure Differential) The maximum difference
in pressure, measured in PSI (pounds per square inch) between the
valve inlet and outlet at which the solenoid can safely operate
the valve.
MEDIA
The material that passes through the valve, i.e. air, gases, water,
hydraulic fluids, petroleum products, corrosive and non-corrosive
liquids and gases.
METERING
An adjustable pin that regulates the flow of media over a specified
path; placed as a restriction in the media path. ORIFICE Opening
inside the valve that can be either open or closed to control the
passage of media.
OXYGEN
SERVICE
Solenoid valves specified for oxygen service require special cleaning,
handling and packaging and are furnished free of any oils or contaminants.
PORTS
Openings through which the media enters and exits the valve.
RESPONSE
TIME
The time necessary for a closed valve to fully open, and for an
open valve to totally close. Voltage, pressure size and media affect
response time. The typical response time for KIP solenoid valves
is 10-12 milliseconds.
SHADING
RING
Usually, a round copper ring is pressed into a groove of the end
stop in all AC (alternating current) valves. The ring overcomes
oscillation and chatter associated with AC valves. Silver shading
rings are available when copper is not compatible with the media.
