We are a primary manufacturer of valves, working mainly in Stainless Steel and Hastelloy. All major valves components are manufactured “in house”, we do not subcontract any element of this work to a third party. One of the great strengths of the company is that it predominantly sells directly to its customers where the problems and solutions to sampling can be thoroughly discussed and resolved. This is particularly important where specials have to be made.
