SETUP PROCEDURE
MOUNTING DISPENSE VALVE
Mounting holes are drilled through the valve body. The valve may be tilted to a maximum of 60 degrees from the
vertical depending on the application.
AIR CONTROLLER
Operation of the Model 715 Dispense Valve requires a controller that can provide the following:
A minimum of 0.5 SCFM (2.3 cm
3
) of dry unlubricated air at a minimum pressure of 70 psi (4.8 bar) and a
maximum of 100 psi (6.9 bar).
Time delay capability to allow the valve to cycle.
Independent air pressure regulators for material supply and valve operation.
“Purge capability”
which is the ability for the operator to pass or not pass air to the valve’s Open port.
For semiautomatic or automatic applications, a foot switch or other control to cycle the valve.
Connection for .16”ID x .25” OD (6.35mm) pressure tubing for use between the dispense valve and controller.
Connection for .16”ID x .25” OD (6.35mm) pressure tubing for use between the controller and material supply
air inlet.
OPERATING PROCEDURES
DRY SYSTEM CHECKOUT
This is an initial checkout to determine if the setup has been properly completed. The dry checkout is conducted
without any material in the system. Refer to the illustrations above or below.
1. Turn on the controller and the air supply.
2. Set the air pressure to 70 psi (4.8 bar) on the system pressure gauge.
3. In the normal “ready” state the Spool (2) is seated in the Posipak Seal (6), sealing the dispense valve. For
this test, remove the Nozzle (5) so that you can visually verify that the Spool (2) extends upon actuation.
4. Momentarily press the dispense valve cycling control switch.
5. The controller applies air to the Open port of the dispense valve, the Spool (2) extends. After the time delay
the controller applies air to the Close port causing the Spool (2) to retract. Visually verify the spool
movement. When this happens, the system is correctly installed.
MATERIAL LOADING
Material is supplied from a pressure vessel or pump with enough pressure to cause a proper rate of flow from the
dispense nozzle. (Note: The material pressure will vary depending on the application.)
Warning: Do not apply either operating or material supply pressure to the product until all screws, material supply
connections and air system connections are in place and properly tightened.
Attach the air line to the regulator and set the air pressure control to the setting required for the application. (Note:
When using a remote reservoir, the delivery tubing and fittings must be compatible with the material being
dispensed and capable of withstanding the dispensing pressure.)
WARNING: Do not exceed 100 psi (6.9 bar) pressure on the operating system. Do not exceed 2000 psi (137.9
bar) material inlet pressure. Higher pressures may cause a hazard or serious injury. Note: The minimum
recommended pneumatic operating system pressure is 70 psi (4.8 bar) clean/dry air.
