The J-Tron PI22W72 distinguishes itself in the competitive landscape through its innovative material selection and uncompromising validation protocols. Engineered to perform reliably even under demanding inlet vacuum conditions, the valve incorporates a high-performance PPS body coupled with FFKM seals, which work in concert to provide exceptional self-priming capability. This robust construction ensures consistent operation where other valves might falter. Beyond its core functionality, the PI22W72 offers significant additional benefits, including an ultra-compact footprint and superior self-lubricating properties. These features make it an ideal component for integration into sophisticated high-precision dispensing equipment, where space constraints and reliability are paramount concerns.
The assembly process reflects a similar commitment to precision and quality. To ensure perfect alignment and connection between the coil and the valve body, a specialized press-fitting procedure is employed. This critical manufacturing step is meticulously supervised by a KEYENCE displacement sensor, which provides real-time, micron-level feedback on the fitting accuracy. This high degree of control guarantees a secure and optimal assembly, directly contributing to the valve's long-term performance and consistency.
For applications that involve exposure to aggressive and corrosive media, a specific variant of the PI22W72 is available. This model is assembled using a proprietary epoxy injection molding process. This technique completely encapsulates critical internal assemblies, creating a hermetic seal that effectively protects the valve's sensitive components from fluid invasion and corrosive attack, thereby significantly enhancing its durability and lifespan in harsh operating environments.
To unequivocally guarantee that every unit meets the stringent performance characteristics promised, each PI22W72 solenoid valve is subjected to a comprehensive suite of factory tests. This rigorous validation is conducted in two critical phases. First, the coil undergoes a full electrical verification, which includes hi-pot (high-potential) testing to check insulation integrity, inner-layer short circuit detection, and precise measurements of resistance and inductance. Second, the assembled valve is put through a series of mechanical and functional tests. These include leak tests under various pressure regimes, assessments of low-pressure activation performance, and precise measurements of its specific activate/hold voltages and operating current to ensure energy efficiency and reliable switching.
