Pressure-temperature ratings and available configurations are confirmed by size, material and design for the specified duty.
High-pressure globe valves for shutoff in power-plant main steam piping, with material and pressure-temperature ratings selected for the project conditions.
Shutoff and selected throttling duties in high-pressure feedwater piping. Required pressure drop and flow conditions determine suitability for the proposed configuration.
Globe-valve service for drains and blowdown piping, with differential pressure, fluid conditions and erosion risk reviewed during valve selection.
Shutoff and selected throttling service in bypass piping and boiler auxiliary steam systems. Capacity and operating duty are confirmed against the project requirements.
Isolation and selected flow-adjustment duties in high-pressure water circuits throughout the power plant.
Y-pattern and T-pattern globe valve configurations are available within the product platform. Provide fluid, operating and design pressure and temperature, flow range, required pressure drop, size, end connections, body material, actuation and shutoff requirements for selection.
Throttling suitability is reviewed for the proposed valve and duty. High pressure drop, cavitation or erosion conditions require configuration-specific engineering review; severe-service control requirements can be evaluated with the related control-valve platform.
Typical U.S. project basis may include ASME B16.34, ASME B31.1 at piping-system level, API 602 or API 623 as applicable, API 598 testing, and ASME B16.10 / B16.25 / B16.5 interfaces. API 624 or ISO 15848 may be requested. Final material, pressure, leakage and project documentation requirements are confirmed for the quoted configuration.
Selected manufacturer project experience; configuration-specific references are reviewed for the quoted valve.
