For use with high purity chemicals. Semiconductor manufacturing equipment. The main body material is made of stainless steel. The seal material uses rubber. Stainless steel (SUS304) is used for the main unit and valve spring. In addition, the main unit has been treated with electrolytic sanding for improved corrosion resistance. Sealing material can be selected according to the fluid and application. Flexible for semiconductor manufacturing process. As a no-grease specification, the seal material does not apply grease. ● Comes in a wide variety of sizes so you can choose the size according to your desired application and flow rate. Each part is cleaned and assembled, inspected, and packaged in a clean room. The plug comes standard with a cap. ● Compatibility: Can be connected regardless of the mounting shape if the same size. Valve structure: 2-way opening/closing type; Can be connected to a semi-concoupler SP type socket (8S).
