API 6A "T"-Pattern Globe Valves, Gate Wedge Valves and High Erosion-Resistant Gate Valves for Geothermal System (Alternative Design Solutions)

About this product

ALTERNATIVE DESIGN SOLUTIONS There are a large variety of available valves and valve configurations for a wide variety of purposes and conditions not tabulated in this catalogue. Some example are listed below. Other valve designs or customised configurations are available on request, contact BFE for special requirements. Globe valves are used to regulate the fluid flowing through the pipeline or in applications that require a frequent and quick opening/closing of the flow. This design is available in various models to cover the various requirements in terms of fluids, working temperatures and pressures. Globe valve design is not common for API 6A upstream application but if required by process operations or specifications it can be performed fully according to the 6A requirements. Gate wedge valve design is not common for API 6A upstream application because there is no through conduit feature but it can be required by process operations or specifications when positive sealing is required (Capability of improving seal tightness by increasing the stem thrust) but double block feature is not necessary. In this case the use of expanding gate design can be avoided with benefits directly as a result of cost-saving. HIGH EROSION-RESISTANT GATE VALVES FOR GEOTHERMAL SYSTEM Conventional gate valves are not designed for flow rate control with severe problems of erosion with the opening from the small to the half and also corrosion problems because of the type of fluids and chemicals involved. BFE design modified the internal of gate wedge in order to match the requirements of geothermal gathering system. This modification made it possible to develop a high erosionresistant gate valve with good flow rate controllability for geothermal gathering system. Key features are the full internal cladding of all wetted surfaces with CRA and full hardfaced with wear resistance alloy specifically selected for geothermal fluids (In geothermal gathering system, it is normally required to control the flow rate with the opening from the small to the half during the well test, start up and heat up operation).
