3000 Series

The Severn 3000 Series Control Valve was initially developed over five decades specifically for installation in cryogenic cold boxes. As such, the 3000 Series now benefits from extensive experience in providing cost effective and easily maintained valves in an industry which makes stringent demands upon its suppliers.

Construction materials of the body are generally aluminium or stainless steel to suit adjoining pipework, while the fully machined flow path minimises particle pick up and ensures a degree of cleanliness necessary for the industrial gas market.
