Since 1969 A+R Armaturen ^® GmbH has been manufacturing valves for various industrial fields. In 1989 the advanced ball valve technology was introduced primarily in the process industries. Since then A+R^® has been supplying ball valves for the most industrial applications. Sophisticated PTFE, PEEK and Carbon seated systems are utilized to ensure the highest level of operational integrity of processes from -120°C (-184°F) up to +350C (660°F). A+R^® ball valves size DN 15 (1/2") - DN 300 (12"), PN 10 - PN 100, 150# - 600# working on various kind of media in industrial application fields. The product models KHF, KHL and KHX, Series 510 and 710 are dedicated to solve the most complex problems in the process industry.

Over a period of more than 35 years, A+R^® have achieved much knowledge on valve machining. The majority state-of-the art CNC machining equipment is available in house to ensure fully controlled machining processes. A high grade of flexibility allows maximal response to special requirements from customers and guarantees punctual deliveries. Strict quality control procedures according to DIN EN ISO 9001:2000 ensure that each valve fulfils all engineering specifications to PED (Pressure Equipment Directive) 97/23/EC, AD-2000, TA-Luft 2002, BS 6755 Part 2, Gost-R, RTN and others.
