The Severn 7000 Series Control Valve was initially developed specifically for installations in cryogenic and warm service Ultra High Purity Systems for the semi conduction industry and is now widely recognised as a high‑performance solution for industrial gas applications, semiconductor manufacturing, and ultra‑clean process control systems. As such, the 7000 Series now benefits from extensive experience in providing cost effective and easily maintained valves in an industry that makes very stringent design demands upon its suppliers including high purity gas control, cryogenic flow management, and precision pressure regulation.
Compact installation has always been a major consideration in Severn control valve designs and therefore Z angle styles are favoured over large Y pattern bodies. Construction materials of the body are generally forged 316L stainless steel to suit connecting pipework, while the fully machined crevice free flow path minimises particle pick up and ensures the degree of cleanliness necessary for this sector of the Industrial Gas market making it ideal for ultra‑high purity valve applications and contamination‑sensitive environments.
