SET (San-ei Tech)

Diaphragm Valve

The SV62-B is a high-precision diaphragm valve specifically engineered for dispensing light-sensitive materials. It uses a black UHMW resin that provides both excellent liquid resistance and high light-shielding properties. This UV-blocking capability makes it possible to apply a fixed amount of low-viscosity liquids, such as UV adhesives and UV anaerobic adhesives, without the risk of premature curing inside the valve. The design ensures a consistent, drip-free application for reliable performance.

    How the Valve Operates

    Air pressure retracts the diaphragm seal, allowing fluid to flow (Figure 1). When the cycle completes, a spring returns the piston and closes the diaphragm to shut off fluid flow (Figure 2).
