SET-UP PROCEDURE

MOUNTING DISPENSE VALVE

For optimum operation, the Dispense Valve must be mounted on a 1/2 inch (12.7 mm) support rod

post or frame. When mounting, firmly affix the valve in place by tightening the Black Socket Head Cap

Screw with a 5/32 inch Allen Wrench. The valve may be tilted to a maximum of ±60

from the vertical

depending on the application.

AIR CONTROLLER

Operation of the 902-20 Dispense Valve requires a controller that can provide the following:

• A minimum of 0.5 SCFM (2.3 cm3/s) of dry, unlubricated air at a minimum pressure of 70 psi (483

kPa).

• Time delay capability to allow the valve to cycle.

• Independent air pressure regulators for material reservoir and valve operation.

• "Purge capability" which is the ability to pass or not pass air to the Lower Pinch-Off Piston on the

Dispense Valve.

• For semi-automatic or automatic applications, a foot switch or another automatic control to cycle the

valve.

•Connection for .16” ID X .25” OD (6.35mm) pressure tubing for use between the Dispense Valve and

controller. (Note: Two 3 foot (1 m) sections of pneumatic air line are provided.)
