Application
A
Multiple double-acting actuators can be operated
simultaneously when powered by a pump.
|
 |
Application
B
Two pairs of single-acting actuators are
independently operated by remote mounted control
valves and powered by one pump. Check valves
prevent return line pressure fluctuations from
affecting released clamps. Pressure port “P”
check valves are built into the control valve.
|
 |
Application
C
Similar to Application C, one pair of single-acting
actuators and one pair of double-acting actuators are
independently controlled by 100969DE directional
control valves. When using more than one directional
valve in one circuit, “P” port check valves 500174DE
are required to prevent loss of clamping pressure in
one circuit while actuating another. “T” port check
valves 500173DE should be used in single-acting
circuits where return line pressure fluctuations may
affect released clamps. |
 |
Application
D
Rotating unions are used to connect pressure and
return lines on applications where fixture rotation
does not allow fixed plumbing. Here, three single-
acting actuators are independently operated by
three remote mounted control valves. Each valve
is connected to the rotating union which in turn, is
connected to a single pump.
|
 |
Application
E
Two single-acting actuators operate simultaneously,
controlled by a remote manual valve. A sequence
valve insures that the workpiece is clamped before
the work support is locked |
 |
Application
F
Similar to Application B, (above) the three
actuators are operated by a remote mounted control
valve.This type of valve allows the pump to be
located away from the workstation.The valve can
be manually operated or, as shown, an electrically
operated remote control valve is used.This valve
can be used to give the operator push-button
convenience or fully automated control by the
machine tool
|
 |
Application
G
Similar to Application F (above), a
double-acting swing clamp is actuated
before sequencing a work support.
When released, the work support drains
back through the sequence valve’s
internal check valve |
 |
Application
H
Like Application C (above), two single-acting
systems are independently operated by remote
mounted control valves. Here the pressure
reducing valve allows each system to have its
own maximum pressure.The cylinder on the
left operates at the pressure of the power
source.The cylinder on the right can be set
at a lower pressure by adjusting the pressure
reducing valve

Application
I
DE-STA-CO’s Manual Pallet Valve is the
simplest way to disconnect the power
source from a pressurized pallet. For use
only with single-acting actuators, it provides
an automatic, leak free shut-off. An
accumulator makes up for temperature
changes and minor leakage. Built-in
filtration protects this valve from
contamination.
|
 |
Application
J
For pallets using double-acting actuators,
DE-STA-CO’s double-acting pallet valve
system uses a pilot-operated check valve to
maintain pressure on the pallet.The three
position directional valve mounts at the
operator’s workstation instead of the pallet.
Any of DE-STA-CO’s standard,
constant pressure pumps operate the
system. An accumulator makes up for
temperature change and minor leakage.
