The GENTLE Teflon Diaphragm Valve Series integrates three models—AV120-F (PTFE flow path), AV120-S (SUS304 flow path), and AV125K2-S (SUS304 high flow)—all air-driven at ≥0.35 MPa with spring return. They support 0.01 mL–1.0 L/min dispensing of 1–1,000 cps fluids, occupy just 22×64–74 mm, weigh 100–175 g, and run up to 200 cycles/min for seamless system integration.
