Oct 09, 2017 The Use of Thermal Spray Coatings for Metal-Seated Valves. Metal seated valves attain sealing by metal to metal contact. A variety of coatings are used to protect valves and actuators against wear and corrosion. In the case of metal to metal sealing surfaces coatings are designed to protect against wear due to galling of the sealing surfaces.
Anchor/Darling Gate valves are designed to provide isolation of a piping system or a component when closed. They are not suitable for modulation of flow, i.e. throttling, and should not be used for that purpose. 1.2 Principles of Operation The principle parts of a flex-wedge gate valve are the body, bonnet, disc, stem and top works (Fig. 1).
