摘要： A gate valve and method according to which a gate body extends within a valve cavity, a fluid bore extends through the gate body, and a passage extends from the fluid bore, through the gate body, and to the valve cavity. The valve cavity is pressurized with a lubricant to prevent, or at least resist, solid particles (e.g., sand, fines, debris, etc.) from entering the valve cavity. The valve cavity and the fluid bore are pressure balanced. In some embodiments, a flow valve, such as a check valve or one-way valve, is positioned within the passage.

摘要： The disclosure provides for a valve including a surface movably engaged with another surface. A coating is on the surface and is characterized by: a CoF of less than 0.1; a hardness in excess of 1,200 HVN; impermeability to liquids at pressures ranging from 15 and 20,000 psi; a surface finish of 63 or less; and a thickness ranging from 0.5 to 20 mils. The disclosure provides for material constructions including a continuous phase, including a transition metal, and a discontinuous phase, including a solid dry lubricant. The disclosure also provides for a method of depositing a coating that includes depositing a first layer of a coating onto a surface using electroplating, electroless plating, thermal spraying, or cladding, and then depositing a second layer of the coating onto a surface of the first layer using sputtering, ion beam, plasma enhanced chemical vapor deposition, cathodic arc, or chemical vapor deposition.
