Heavy Duty: Precision at Temperatures from -50 °C to 550 °C and Pressure drops up to 200 bar. Designed for the precise regulation of media in demanding industrial and power plant processes, our Heavy Duty series shut-off and control valves are expertly engineered for applications with high pressure and temperature requirements. Built to withstand temperatures ranging from -50 °C to 550 °C and pressure drops up to 200 bar, these valves are made from high-performance materials and feature a robust construction. Their design focuses on longevity, optimised operating costs, and minimal downtime. We’ve thoughtfully designed the Heavy Duty series so that technicians can easily access and replace high-wear components when needed.
