Air
The Model 400 needle valve requires a Model 345 valve controller or a 2-position, 4-way
air solenoid valve to actuate the air section. The valve should be operated with clean,
dry air between 80-100 psi [5.5 - 7 bar]. One #10-32 threaded air port is located on the
valve. This port is used to open the valve when air pressure is applied and close the
valve when air pressure is relieved. A quick-connect air fitting is typically supplied with
the Model 400 to fit 0.16" [4 mm] tubing.
Fluid
The Model 400 needle valve requires a material reservoir or pressure tank to draw
material from. The material reservoir should be connected to the Model 400 valve
through the 1/8" [3.2 mm] NPT port located on the valve.
