KOGANEI's TAC Air Valves series, an acronym for "Tiny Air Components for Total Air Control," presents a comprehensive range of compact devices engineered for total pneumatic control, enabling the straightforward setup of simple automation circuits. The catalog highlights a diverse product portfolio, encompassing basic valves (push-button and lever types), various operators for actuation (manual/mechanical and air pilot types), and crucial peripheral components such as regulators, quick exhaust valves, check valves, pneumatic-electric transducer switches, volume tanks, and pressure gauges. From a technical standpoint, these valves are available in 2, 3, or 5-port configurations, typically operating within pressure ranges of 0 to 0.9 MPa and capable of withstanding proof pressures up to 1.35 MPa. Effective areas range from 1.8 mm² to 5.5 mm², supporting flow coefficients (Cv) between 0.08 and 0.27. Specialized operators like the 34AS offer snap-action for precise timing, while the 34AR features a unique self-return function, automatically resetting within approximately 0.5 seconds even under continuous pilot pressure. The advanced TAC2 series further extends functionality by permitting reverse flow through all ports. The applications for these valves are extensive, covering a broad spectrum of pneumatic control tasks. These include direct and indirect operation of single and double-acting air cylinders, implementation of AND/OR logic circuits, precise timing operations, continuous reciprocating motion, step control, and complex sequential automation processes. The series is meticulously designed for reliable performance across diverse industrial environments, prioritizing ease of integration and consistent operational stability。.
