VALVES FOR THE TANK FARM
Six, Eight, or even Ten and Twelve-inch Valves for transporting gas from the Tank Farm to the Fab is no problem, Evans provides these large Ball Valves with the same Purity and Leak Integrity Specifications found in our smaller Valves.
ISOLATION VALVES
Evans offers a full size range of High Purity Isolation Valves, and a variety of End Caps to meet the differing requirements of our customers. Tubing, Pipe, JIS, Compression, all come as End Cap options on the Evans High Purity Ball Valve. Purge Ports and Purge Valves can also be purchased as additional options.
INTEGRATED VALVES AND MANIFOLDS
Evans first introduced the High Purity Integrated Ball Valve to our customers in 1995 by close coupling the Evans Ball Valve with a short stretch of tube. This new integrated design improved end product quality, and at the same time reduced customer cost and time of installation. Today Evans has gone a step farther, and, together with Dockweiler AG has brought to our customers The Manifold. Manifolds are twenty foot, or six meter, lengths of tube, with close-coupled Evans High Purity Ball Valves attached along the tube at customer-designated intervals. Designed as sections of a Lateral, Manifolds are shipped CFOS cleaned, leak tested, and ready for direct installation within the customer’s non-process gas systems. This new design and method of construction has once again improved product quality and
saved customer time and money. As example, a twenty foot Manifold with four valves attached will eliminate between eight and twelve welds in the field, and by eliminating much of the cutting, facing and field fit-up of individual fittings and components, tremendous savings in time and waste material is realized too. Third Party qualification is simplified as well.
