The Severn 7000 Series was initially developed specifically for installations in cryogenic and warm service Ultra High Purity Systems for the semi conduction industry. 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.
Compact installation has always been a major consideration in Severn 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.
Design Features:
- Smooth profile crevice free body construction
- High-capacity body
- Electronic Grade surface finish options
- Large choice of trim sizes
- Robust parts for trouble free service and low cost of ownership
- Inherently characterised trims available in linear, equal percentage and semi throttle

Benefits:
- Top entry servicing with direct access to plug assembly
