Adjusting Material Flow

Figure 5. Model 826 Flow Adjustment Procedure Components

It is very important that the Tube Support (Figure 5, M) be firmly in place for the valve to

function properly. Check to be sure that the Tube Support is flush against the Valve Body

(Figure 5, F).

To set the Piston (Figure 5, A) for the proper pinch of the fluid path (amount of closing and

opening) with the Tube connected to the Material Reservoir, gradually pressurize the Reservoir

and adjust the valve-piston pinch using the following steps:

Set the Reservoir's pressure to 5 psi [0.3 bar].

Note: If the Pinch Stop Screw (Figure 5, K) prevents the Piston (Figure 5, A) from closing the

Tubing, flow will begin as soon as the Reservoir is pressurized.

With the hex wrench provided, turn the Pinch Stop Screw (Figure 5, K) counter-clockwise

until the Tube is sufficiently closed to stop the flow of material.

After the Tube is sufficiently closed, slowly turn the Pinch Stop Screw (Figure 5, K)

clockwise until drops of liquid form at the Nozzle Tip (Figure 5, G).

Turn the Pinch Stop Screw (Figure 5, K) counter-clockwise just enough to close the Tube

and stop the flow, but not to over-pinch it. Turning the screw 15 degrees more than zero-
