Stop Valve J41Y-40I for Mejia Power｜YOYIK

Stop Valve J41Y-40I for Mejia Power (New Energy Power System)｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41Y-40I is a medium-high pressure stop valve with PN40 (≤4.0MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation. Developed specifically for Mejia Power’s new energy power systems (including photovoltaic power-related facilities) , it features hard alloy sealing (Y suffix), high-quality chrome-molybdenum alloy steel (I suffix) material, and excellent sealing performance and pressure-bearing stability, suitable for harsh industrial working environments of new energy power plants. Therefore, we have set strict safety standards in every link such as product design, production, and testing.

It is mainly used for medium isolation in Mejia Power’s medium-high pressure auxiliary pipelines, steam pipelines and instrument loops of new energy power generation facilities, compatible with high-temperature steam, water and hydraulic oil in photovoltaic and other new energy power systems . With max working temperature 550℃ and pressure 4.0MPa, it ensures absolute tightness and safe operation of the pipeline network. We also continuously optimize safety protection measures based on actual operating conditions of Mejia Power’s new energy projects to ensure that each product can operate stably in harsh environments.
