The Company
RAV Armaturen GmbH, based in Hattingen, specialises in valves for safety-critical industrial plants. The product range includes precisely machined ball valves – including fully welded ball valves, subsea ball valves, split-body, through-bore, multi-port, tapping/under-pressure tap and demand-connection ball valves as well as custom designs built to customer specifications or drawings – plus a broad assortment of industrial valves such as actuators, filters, dampers, expansion joints, control valves, gate valves, strainers and safety valves. In addition, the company supplies gas equipment such as gas pressure regulating devices, safety shut-off and relief valves, excess flow regulators and vacuum regulators, as well as individually engineered natural gas expansion turbines for power generation in gas pressure regulating stations. Materials used include steel, stainless steel, cast materials, non-ferrous metals, plastics, PTFE, rubber and fabric. The products are manufactured under a quality assurance system that meets international standards and approvals, and are delivered worldwide. Customer industries include the gas industry, pipeline construction, district heating, petrochemicals, and oil and gas facilities, onshore/offshore platforms, shipbuilding and power plants.
