API600 Duplex Steels Flexible Wedge Gate Valve Class150 For Oil Gas Applications
Product Review
TEKO gate valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening.

Application
Cast gate valves provide optimum performance in conditions where high flow efficiency, tight shut off and long service is required. A wide choice of shell and trim materials do cover the whole range of applications, from the every-day type of non-corrosive service to critical service with highly aggressive media.
