ARCA Regler GmbH, the parent company of ARCA Flow Group, is a leader in control valve technology. For more than 100 years the company has concentrated on the development, production, sales and service of pneumatic and electrically-activated control valves. Continuous product development and many patents have resulted in ARCA’s being honoured as one of the 100 most innovative firms in Germany.
von Rohr Valves and WEKA Cryogenics (Switzerland) as well as ARTES Valve & Service and FELUWA Pumps in Germany are the other companies of the ARCA Flow Group. Production plants and joint ventures in China, Korea and India are backed up by a global sales network, providing excellent technical advice and lifetime service.
In industrial process control, ARCA has established a new standard with the modular ECOTROL® control valve system. In a range between ½” (DN15) and 32” (DN800) and rating up to Class 2500 (PN400) the unique SWS quick exchange system offers a solution for each application.
Features from ARCA, that count:
• Excellent performance at the most demanding of requirements
• Low life cycle costs
• Large range of sizes & ratings
• Low noise, multi-step trims
• Reliable in steam- and feed water applications
• Easy-to-service modular construction
The better solution!
ARCA rounds off the proven series of ECOTROL®control valves at the high end with the new development of the nominal size DN 700 (28”). This valve has been specially optimised for use as an anti-surge valve on turbocompressors, but can also be used for all control applications involving liquid and gaseous media. In combination with the associated spring-return pneumatic piston actuator this valve offers a technically and economically ideal solution for many applications.
Advantages that should not be kept quiet!
• high reliability guaranteed by precision manufacturing processes and quality control
• emission control and leakage conforming to the highest international standards
• tubeless, integrated mounting of positioners
• acc. to VDI 3847 or
• with OPOS®-Interface, the ability to safely replace the positioner during operation
• minimal working life costs
Take advantage of the most technically innovative control valve in a generation up to DN 800 (32”)!

The ECOTROL® 8C control valve has proven itself in over 15 years of use in the process industry, whether in energy technology, in chemical and petrochemical processes or in water and environmental technology. With the unique clamping seat system that enables simple maintenance without special tools, the stainless steel stuffing box chamber - irrespective of the housing material - and the patented soft seal, the introduction of the ECOTROL® 8C control valve set new standards for industrial control valves. The associated actuator type 812 was also a trendsetting innovation with its innovative diaphragm clamping by secondary path of force, the direct attachment of ARCAPRO® and SIPART PS2 positioners and the possibility of blanketing the spring chamber with instrument air (with air guidance through the actuator stem, i.e. without external piping).
ARCA rounds off the proven series of ECOTROL® control valves at the high end with the new development of the nominal size DN 700 (28”). This valve has been specially optimised for use as an anti-surge valve on turbocompressors, but can also be used for all control applications involving liquid and gaseous media. In combination with the associated spring-return pneumatic piston actuator, which can be operated in both single-action mode and (for significant improvement of the control dynamics while maintaining a defined safety position in case of a failure of signals or power) double-action mode, this valve offers a technically and economically ideal solution for many applications.
The ARCA angle style control valves series 350 and 380 have since long proven themselves in various applications under critical process conditions. Whether used for the control of steam or process gas at high pressures and temperatures, in the cavitation-free relaxation of liquids at a high pressure ratio or in the handling of gases and fluids with solid contents; the modular system of valve housings, trim styles and appropriate material combinations always offers an ideal solution.
