Spray Valve

The SV59MS is a spray valve specifically designed for ultra-fine, non-contact, thin-film spray coating. It utilizes a small diameter nozzle to achieve a precise application, and its design allows for stable thin-film coating even in narrow spaces. The valve features excellent liquid drainage properties, thanks to a liquid stopping mechanism inside the nozzle, which effectively reduces scattering.

How the Valve Operates

Air pressure retracts the piston needle from the hub of the dispensing tip, allowing fluid to flow (Figure 1). When the cycle completes, the spring returns the piston needle to its sealed position in the tip, shutting off fluid flow (Figure 2).
