Our high-performance J-type transfer valve is engineered for ultra-high vacuum (UHV) environments, offering a compact, space-saving design with exceptional sealing reliability. Built from high-grade stainless steel or aluminum, it supports bakeable operations, low outgassing, and long-cycle maintenance-free performance, making it the ideal choice for semiconductor manufacturing, vacuum coating, and advanced research facilities.

Our high-vacuum S-type transfer valve is engineered for ultra-high vacuum (UHV) environments requiring low flow resistance and high cleanliness. Featuring a streamlined S-shaped design, it minimizes turbulence and particle accumulation, making it perfect for semiconductor, thin-film deposition, and research applications. With options for metal or rubber seals, bakeable capabilities, and long-cycle durability, this valve provides a reliable, maintenance-free solution for critical vacuum process control.
