IF YOU KNOW THE SERIES YOU REQURE, consult
the table of contents to find the series you have selected.
The section is laid out so that the most commonly used valves
are illustrated and all the options are displayed in tables.
|
|
IF YOU DO NOT KNOW THE SERIES YOU REQUIRE,
first decide whether you need a 2, 3 or 4-way valve (see Note
1 at the foot of this page); next decide the flow and port size
required. Then consult the table of contents. |
| In either
case, the checklist below will help you determine the exact
model code you require. For further information, please consult
the Precautions
section, or call 847-364-7455.
How to Order MAC Valves
|
| Step
1: 2 or 3-way Valves |
|
Step 1: 4-way
valves |
| Note: A MAC 2 way
is a 3 Way with one port plugged.
Normally Closed or Normally Open?
Pressure range: 25 to 150 psi or below 25 psi? (below 25
psi on external pilot connection is required for pilot operated
valves) (See Note 2 below)
Single operator, spring return? (See Note 3 below)
|
|
Single
operator, spring return or double opeator?
Pressurerange: 25 to 150 psi (single operator)? (See Note
2) 10 to 150 psi (double operator)? (See Note 4)(below these
minimum an external pilot connection is required for pilot
operated valves)
2 position or 3 positions? If 3 position: which center position?
open______closed______or pressure center______?______
|
| Step
2: What kind of operator? |
|
Step
3: Cv and flow requirements |
| Solenoid, Remote
air or Mechanical? If remote air or mechanical, go to step
3.
If solenoid, AC or DC? If DC, what voltage and power (watts)?
Electrical connections? (See Note 5 below) |
|
Port
size? (NPTF)
Valve mounting: inline? stacking? manifold base? circuit
bar? (See Note 5)
Integral pressure regulators? (See Note 5)
Integral flow controls? (See Note 5)
|
| Keep In Mind... |
| All MAC
4 Ways can be used as 3 Ways or 2 Ways by simply plugging the
appropriate port or ports; however in certain applications where
considerations of size, speed, flow or cost are important, it
may be preferable to select a 3 Way valve for a 3 Way application.
|
| A Note About Pressure |
|
Minimum pressure for the internally piloted 55 series valves is 30 psi. Maximum
pressure for the 35 and 45 series is 120 psi.
|
| Single and Double Operated Spring Return |
| MAC 3 Ways
are all single operated spring return. For double operated 3
Ways, use a 4 way and plug the appropriate cylinder port.
|
| Minimum Operating Pressure |
| For 3 position
valves, minimum operating pressure is 25 psi.
