Angle Globe Valve – Combining Flow Control with 90° Direction Change
Angle globe valves uniquely integrate a globe valve’s throttling capability with a 90-degree elbow function, eliminating one pipe fitting while providing superior pressure recovery compared to straight-pattern designs. This body configuration proves essential where piping layout requires both flow control and directional change, reducing installation costs and pressure drop in African refineries, power plants, and chemical facilities.
The single 90° turn through the valve body creates a more streamlined flow path than the traditional Z-body globe valve, which forces fluid through two direction changes. This geometry reduces turbulence, lowers pressure drop by approximately 30-40% compared to straight patterns, and minimizes erosion in high-velocity steam and liquid applications common throughout South African power generation and Nigerian petrochemical complexes.
International engineering firms specify angle globe valves per API 602 and ASME B16.34 for applications including turbine bypass systems, pressure-reducing stations, and process control where the 90° inlet-to-outlet configuration simplifies piping while maintaining precise throttling characteristics. These valves excel in services requiring Class IV to Class VI shutoff with flow entering under the seat for pressure-assisted closure.

Global Applications
High-pressure steam bypass around turbines during startup, shutdown, and load rejection in coal-fired plants (South Africa), combined-cycle facilities, and geothermal installations (Kenya). Angle configuration naturally accommodates turbine inlet geometry while providing precise pressure reduction with anti-cavitation trim.
Steam and gas pressure letdown in African refineries, chemical plants, and industrial facilities. The 90° flow path provides superior pressure recovery while maintaining linear flow characteristics for accurate control, reducing downstream turbulence that causes noise and vibration in conventional straight-pattern designs.
Power plant boiler feedwater regulation and turbine extraction piping where space constraints and piping layout favor the right-angle configuration. Hardened Stellite trim withstands high-velocity feedwater erosion common in Egyptian and Nigerian power generation facilities.
Chemical injection, catalyst feed, and reactor temperature control in African petrochemical complexes requiring both throttling capability and directional flow change. Exotic materials (Hastelloy, Monel) available for corrosive service in North African fertilizer and specialty chemical plants.
Wellhead chokes, separator level control, and glycol circulation on West African platforms (Nigeria, Angola, Ghana) where compact design and weight savings are critical. Pressure seal bonnets rated to Class 2500 handle high-pressure subsea production conditions.
Steam trap bypass, condensate removal, and drain valve applications in power plants and industrial steam systems. Natural downward-discharge orientation suits gravity drainage while providing tight shutoff to prevent steam loss through drain lines.
