Valve Selection
Something to remember when choosing which equation to use for valve selection
1. In many instances temperature is not a
factor in system applications. In most
industrial application, compressed air
temperature is roughly the same as ambient.
If this is the case, then the use of equation
#1 is recommended. This equation has been
widely accepted to get a Cv value.
2. If temperature is a factor in the application
then equation #2 is recommended. We have
chosen to use the constant 22.48 in our
equations, but those who choose to be more
conservative may choose use 22.67 as the
constant. Both tied to ambient temperature.
3. When sizing a valve by calculating the Cv
value, determining the pressure drop across
the valve (i.e. ∆P), is an important step.
What has proven to be a good practice in
calculating Cv is the following:
(Eq. 1) Simplified equation when temperature is not a factor
1.024 x Q
Cv =
∆P x P2a
Given:
Cv = Flow coefficient
1.024 = Constant
Q = Peak Flow Rate in SCFM
∆P = Pressure drop across the valve
(See information above)
P2a = Down-stream (valve’s outlet ) pressure in PSIA
a. For general applications use 10 psi for the
pressure drop.
b. When a more conservative approach is
needed, use 5 psi for the pressure drop.
c. If cylinder and design factors are critical,
then using a 2 psi drop will more
conservatively size the valve.
4. Also remember that, for calculation
purposes, whether P1 is given in PSIG or
PSIA, P2 needs to be reflected in absolute
or PSIA (i.e. P2a)
5. Lastly, we recognize that not all applications
will have a supply pressure of a higher valve:
thus it is suggested that if P1 is 60 PSI or
less, a 5 PSI pressure drop across the valve
be used to calculate the Cv value.
(Eq. 2) Equation used when temperature is a factor in system application
Cv =
Given:
Q
(
22.48
Cv = Flow coefficient
22.48 = Constant (22.7 is often used, but 22.48 will be used on the PS exam)
TR = Temperature in Rankin (°F + 460)
Q = Peak flow retain SCFM
∆P = Pressure drop across the valve
(See information above)
P2a = Down-stream (valve’s outlet ) pressure in PSIA

Pipe Thread Quick Reference
Tapered pipe threads seal at the points where the crests of the threads meet the roots of the
mating threads. Standard pipe threads, NPT, PT, and BSPT require sealant to prevent the
development of a spiral leak path. NPTF threads are designed to crush the points of the
crests into the roots of the mating threads to achieve the same purpose, however, use of a
lubricant or sealant to prevent galling of the threads is preferred where not functionally
prohibited.
BSPT – British Standard Taper Pipe Threads
PT – Japanese Industrial Standard Taper Pipe Threads
{R (PT) – Taper external threads}
{Rc (PT) –Taper internal threads}
NPT – American National Standard Taper Pipe Threads
*All of the above are designed to be used with sealant to provide a pressure tight joint.
NPTF – American National Standard Dry seal Pipe Threads
*Designed to provide a pressure tight joint without the use of sealant.
PF – Japanese Industrial Standard Parallel Pipe Threads
*Straight threads use a gasket or O-ring to produce a pressure tight joint.

Valve Functions
A directional control valve determines the flow of air between its ports by opening, closing or
changing its internal connections. The valves are described in terms of: the number of ports, the
number of switching positions, its normal (not operated) position and the method of operation.
The first two points are normally expressed in the terms 5/2, 3/2, 2/2 etc. The first figure relates to
the number of ports (excluding pilot ports) and the second to the number of positions.

Port Identification
The denominations or nomenclature used to identify
the various ports was not uniform until the 5/2 and 5/3
valves were invented. Until the 5/2 and 5/3 were
invented, there was more tradition than any respected
standard.
Originally, the codes previously used for older
hydraulic equipment were adopted. “P” for the supply
port comes from “pump”, the hydraulic source of fluid
energy, and is understood to mean “pressure” in
pneumatic systems.
The outlet of a 2/2 (two ports, two positions) or 3/2
valve has always been "A”, with the second, antivalent
output port labeled “B”.
The exhaust port was originally labeled “R” from
Return (to the oil tank). We can think of R as return to
atmosphere in pneumatic systems. The second
exhaust port in 5/2 valves was sometimes named S, or

the former “R1” and the latter “R2”.
The pilot port initiating the power connection to port A
has originally been coded “Z” (the two extreme letters
in the alphabet belongs together) and the other “Y”.
After 20 years of bargaining about pneumatic and
hydraulic symbols, one of the ISO work groups had the
idea that ports should have numbers instead of letters,
thus delaying the termination of the standard ISO 1219
by another 6 years. Supply should be “1”, the outputs
“2“ and “4”, the pilot port connecting ”1” with “2” is then
“12” etc. Table A shows the main sets of port identifications in use. Preferred are now the ISO 5599 numbers.

Monostable And Bi-stable
Spring returned valves are monostable (stable in one default or preferred condition). They have a defined
preferred position to which they automatically return. A bi-stable valve has no preferred position and remains
in either position until one of its two impulse signals are operated.
Valve Types
The two principal methods of construction are Poppet and Slide with either elastic (rubber) or metal seals.

Auto Switches
REED SWITCHES: A thin metal contact is drawn closed by the magnetic field of the
piston magnet. Since this is a mechanical switch it will wear out over time and is
susceptible to vibration and shock. Their advantage is that they are inexpensive and
can be used with AC voltages.
SOLID– STATE SWITCHES: The magnetic field generated by the piston magnet
causes a current flow inside the switch. Since there are no moving parts, the switch life
is much longer than a reed switch and they are less prone to vibration and shock. They
are more expensive, can only be used with DC voltages and you need to know whether
you need a sinking or sourcing switch.
Current Sinking (NPN) –The switch sensor “sinks” current from the load through the sensor to
ground. The load is connected between the positive voltage supply and the output lead of the sensor.

Circuit
Current Sourcing (PNP) – The switch sensor “Sources” current through load to ground. The load is
connected between the output lead of the sensor and the negative “ground” lead of the supply.

Main
Circuit
Three wire DC sensors include one wire that provides voltage to the sensor, an output signal wire
and a ground wire. Most electro–mechanical loads (relays, counters, solenoids etc.) can use
either a sink or source type switch provided it is wired properly. The proper sensor type must be
chosen when used with solid-state load and programmable controllers due to the fact that some
of these loads must be grounded.
Wire Colors: SMC has changed the wire colors on all of our switch products. This was
done to conform to European standards that are being adopted worldwide.

Sourcing – PNP is often referred to as Sourcing, because
the switch closes and provides the source voltage to the load
Sinking – NPN is often referred to as Sinking, because the
switch closes and sinks the current to ground
Normally Open – Does not pass the signal until the set point
is reached
Normally Closed – Passes current until the set point is
reached
FS or Full Scale – The maximum setting minus the
minimum setting.
Ex. ITV1050 0.9MPa – 0.005MPa = 0.895 MPa Full Scale
(130.5 psi – 0.725 psi = 129.775 psi)
Linearity – The nearness with which the plot of a signal, or
variable, plotted against a prescribed linear scale approximates a straight line. Output error to reference value
Repeatability – The ability of the instrument to provide the
same output every time for the same input. Usually given as
a % of the FS value
Sensitivity – Often described as the minimum change of
input to which the system is capable of responding. Usually
expressed in % of Full Scale
Hysteresis – The difference in output when the measured
value is first approached with increasing and then decreasing
values. Expressed in % of Full Scale
Impedance – Resistance of a load that hinders the flow.
Current Consumption – The amount of current needed for
normal operation, does not include load current.
Watts (W) and Volt Amps (VA) – Both of these units are
used to express electrical power.
Watts is for DC voltage and Volt Amps is for AC voltage.

entry in the Product Application Database that explains basic

NEMA Ratings (Electrical Enclosures)
An enclosure is a surrounding case constructed to provide a degree of protection to personnel
against accidental contact with the enclosed equipment and to provide a degree of protection to
the enclosed equipment against specified environmental conditions. These are the more
common classifications as they pertain to pneumatic components such as valves.
NEMA 1 Intended for Indoor use primarily to provide a degree of protection against contact
with enclosed equipment.
NEMA 2 Intended for indoor use primarily to provide a degree of protection against limited
amounts of falling water and dirt.
NEMA 3 Intended for outdoor use to provide a degree of protection against windblown dust,
rain, sleet and external ice formation.
NEMA 3R Intended for outdoor use to provide a degree of protection against falling rain, sleet
and external ice formation.
NEMA 3S Intended for outdoor use to provide a degree of protection against windblown dust,
rain, sleet and provide for operation of external mechanisms when ice laden.
NEMA 4 Intended for indoor and outdoor use primarily to provide a degree of protection against
windblown dust and rain, splashing water and hose directed water.
NEMA 4X Intended for indoor and outdoor use primarily to provide a degree of protection against
corrosion, windblown dust and rain, splashing water and hose directed water.
NEMA 6 Intended for indoor or outdoor use primarily to provide a degree of protection against
entry of water during occasional submersion to a limited depth.
