Top Entry Ball Valve
Top Entry Ball Valve
Kent Top Entry Trunnion Mounted Ball Valve is an advanced design of Top Entry ball valve, manufactured in a wide range of diameters and pressure classes, and is used in pipelines and critical process applications. These valves are fully in-line field repairable, thus eliminating long down times. The bolted construction allows disassembly on-site for inspection and possible repair. Removal of the bolted cover from the valve body allows access to the ball and seats, which can be removed with special maintenance tools. The valves have standard design features such as a built-in cavity relief mechanism, anti-static, emergency sealant injection, drain and vent, and intrinsic double block and bleed facility. Other standard features of these top-entry ball valves are as below. • Full Internal weld overlay or weld overlay on seat pocket area and body cavity can be provided with in-house cladding facility. • Metal seated valves seat and ball surface are either Tungsten carbide, Chromium carbide coated or Stellite Coated with in-house HVOF coating technology. Fully welded ball valves are also offered, eliminating the potential flange leak path and increasing resistance to pipeline pressure and stress with an in-house welding facility. • Stem extension can be provided depending upon the customer’s requirements. • Seat construction with Single piston effect and double piston effect can be provided. • All valves are fire safe tested as per API 607 / API 6FA.
