RTK Valves for Industrial Control and Process Applications
Rapid Allweiler supplies RTK valves for control, shut-off, pressure regulation, steam, thermal oil, process and industrial fluid handling applications.
RTK is a German control valve specialist offering shut-off and control valves, actuators, regulators, manual stop valves, strainers, sensors and electric components for demanding industrial systems. Rapid helps customers identify the right RTK valve route for their application, operating conditions, documentation requirements, and procurement process.
What Is RTK?
RTK, or Regeltechnik Kornwestheim GmbH, is a German valve and control technology brand focused on industrial control valves and related control system components. The brand’s product range includes motorized control valves, shut-off valves, actuators, pressure regulators, manual stop valves, strainers, sensors, and electric components.
RTK valves are used in systems where accurate control, shut-off, pressure regulation, or process reliability is required. Their valves are relevant for water, steam, air, thermal oil, neutral fluids, non-aggressive fluids, and specialist industrial applications, depending on the product range and operating conditions.
Rapid supplies RTK valves to customers who need technically suitable valve products for plant, process, pump, steam, thermal oil, heating, cooling, and industrial applications. Our role is to help clients gather the right technical information, identify the relevant RTK product category, request documentation, and move from enquiry to quotation with confidence.
