Abstract

Control valve body is moulded by locating a preformed lining of corrosion resistant material, e.g. PTFE or stainless steel, in a mould cavity shaped to the desired shape of the valve body. Synthetic resin is injected into the cavity about the lining and hardened to form the valve body. A cavity between the lining and body, produced by shrinking of the body material, can be filled by injection of cold curing elastomeric material.
