KOGANEI CORPORATION
Koganei PRS Precision Stainless Steel Regulator

Manufacturer: KOGANEI CORPORATION
Features
This regulator allows high-precision pressure settings with a sensitivity of 0.001 MPa (0.15 psi), and it supports accurate carrier gas control in solvents, pure water circuits, and clean air systems. Moreover, it ensures reliable gas pressure control for liquid crystal and semiconductor processes, which improves consistency in demanding environments. Additionally, it operates within a contamination-controlled manufacturing process, creating dependable quality.
Furthermore, the uniquely developed balance configuration enhances the performance of the main valve and increases overall stability. In addition, the normally bleed type design achieves a low consumption flow rate of less than 2 L/min (0.07 ft³/min ANR), which reduces energy usage. The push-lock mechanism also enables simple and secure pressure adjustment, offering smooth and user-friendly operation. Meanwhile, all gas-contacting parts use SUS316 or fluoro rubber materials, ensuring excellent durability and chemical resistance. Finally, an optional pressure gauge is available, allowing quick and convenient pressure verification.
