SCHROEDAHL develops and produces high-quality and individually configured steam pressure reduction control valves
We develop steam pressure reduction valves, which are precisely adapted to the requirements in power plant or industrial processes. SCHROEDAHL single and multi-stage solutions cover all pressure ranges, mounting situations and nominal widths.
Based on the process data, we supply our customers with tailor-made control valves for the optimum operation of their plant. You can benefit from our extensive experience and engineering at the highest level.
SCHROEDAHL steam pressure reduction control valves are high-quality products that are fully function-optimized through continuous further development. It was possible to minimize the actuator forces even during high pressure applications, which in turn leads to the use of smaller and costsaving actuators.
The internal construction is designed for low noise operation, which guarantees environmentally friendly handling. Forged housings combined with a consistent, well thought-out engineering ensures a strong, durable and resistant quality.
