Pneumatic Angle Control Valve

产品概览

The Pneumatic Angle Control Valve is a high-performance flow control solution designed for precise regulation of fluids in high-pressure drop and erosive applications. Featuring a compact angle body design and a diaphragm-style pneumatic actuator, it ensures reliable operation in demanding environments such as steam systems, power plants, and chemical processing units. Its unique geometry minimizes turbulence and erosion, making it ideal for applications with high ΔP and particulate-laden media.

应用

Steam Systems: High-pressure steam letdown and desuperheating.

Power Generation: Feedwater control and turbine bypass.

Chemical Processing: Erosive slurry control and abrasive media handling.

石油和天然气: Choke valve applications in wellhead control.
