SV91CD

Non-contact dot, Spray Line, can be selected with one valve

SV91CD is designed to dispense conformal coating materials into three different patterns, “non-contact dot,”“spraying” or “line dispensing,”to properly cover a restricted area.

How the Valve Operates

 <Non-contact dot dispensing＞

Input air pressure retracts the piston needle from the nozzle seat, allowing fluid to flow. (Figure 1) Piston needle’s instant shut-off creates non-contact dots. (Figure 3)

＜Spraying>

At the same time as (Figure 1), the nozzle air flows around the air cap to atomize the fluid into fine droplets. (Figure 2) Once the cycle is completed, the spring returns the piston needle back to its position to shut off the fluid. (Figure 3)

＜Line dispensing＞

Input air pressure retracts the piston needle from the nozzle seat, allowing fluid to flow to create a bead for the duration that it remains open. (Figure 1) Once the cycle is completed, the spring returns the piston needle back to its position to shut off the fluid. (Figure 3)
