Clean break, low pressure couplings

SAE flanges SCHWER Fittings supplies a wide range of SAE flange combinations in various sizes. All items are available in standard series 3000 PSI / ISO 6162-1 (SAE J518 Code 61) and in the heavy series 6000 PSI / ISO 6162-2 (SAE J518 Code 62). Schwer stocks the flanges in both stainless steel AISI 316TI and carbon steel zinc plated chrome VI free. As standard, the flanges are supplied with FKM seals 85/90 shore for stainless steel and NBR seals 90 shore for steel. Counter flanges are standard without O-Ring and with female threads. The flanges are forged and of high tensile strength. SAE flanges are used in areas where strong vibration, high pressure peaks and mechanical stress occur, in industries such as offshore, shipbuilding, hydraulic, petrochemical and paper machines. Schwer Fittings SAE flanges with welding ends are offered as butt weld or socket weld. Schwer Fittings GmbH – Germany info@schwer.com www.schwer.com Further characteristic features are mini- mal pressure drops and high flow rates due to a flow-enhanced design. Power loss caused by friction is minimised and the energy demand is reduced. NEW, robust, clean break, low pressure couplings in the CT series by Walther- Präzision are designed for multi-purpose use in chemical and fluid technology, hydraulics, machine and systems engineering, process engineering as well as medical and food applications. Manufactured fromtop-qualitymaterials (stainless steel), the CT series is suited to aggressive and toxic substances, in the pressure range from vacuum to 64 bar. The clean break technology of the CT series enables the user to connect and disconnect the non-drip, non-squirting coupling safely and quickly, optimising environmental and user safety.

also developed a purpose-built valve technology for special applications, eg for high temperature applications.” The clean break couplings are manufactured as standard from stainless steel and come with an ATEX approval. With its nominal sizes 5, 7, 9, 12 and 19mm, the new series complements the company’s range of couplers, whose larger nominal sizes cover 25 to 100mm.

Quick connection and separation times require only low coupling forces, with a safe and simple one-hand operation through the integrated automatic lock. The coupling can be safely connected even under residual pressure. “The way we planned the CT series, the coupling can even be used for demanding applications without any modifications,” explained Dipl-Ing Dirk Heinrich, head of development at Walther-Präzision. “We even developed and successfully introduced an advanced thermal insulation for the CT series that protects the user and we
