Series 630 Overflow and pressure control valves made of gunmetal, straightway form, with threaded ­connections

Product informationThe strainers of the 2143 series consist of a straight-through housing made of high-quality stainless steel and, in the case of the 2183 series, of lead-reduced gunmetal. The strainer unit is integrated between the housing and the cover and can be designed with different mesh sizes. The installation of the strainer prevents contamination in the medium and in the downstream process. connection types Internal pipe threadButt weldsSocket weldMore information please go link: 2143

Product informationWith the high-pressure overflow valves of the 493 series, Goetze offers an innovative solution for protecting high-pressure systems.The 493 series includes two different designs – design I and design III – that are specifically designed for different installation situations, pressure ranges and operating conditions. Whether in hydrogen compression, pump protection or gas liquefaction – the 493 series is the optimal solution for demanding high-pressure applications.As soon as the set maximum pressure is reached, the valve opens automatically and diverts excess medium into a low-pressure area or a return line. This protects high-pressure pumps, compressors and pipelines from overload and reduces the risk of system failures.The 493 series is available in two designs that offer specific advantages depending on the application requirements. Design I covers a pressure range from 50 to 500 bar and has a rotatable outlet stroke that allows for flexible installation. By contrast, design III is designed for pressures up to 1000 bar and is particularly suitable for robust applications. With a fixed angle housing, the design III is back-pressure compensated up to 500 bar, which ensures particularly stable pressure control even in demanding environments. While design I impresses with a wide temperature range of -196 °C to +200 °C, design III is optimised for operating temperatures between -10 °C and +150 °C.The robust stainless steel construction of both designs also ensures high corrosion resistance and a long service life, even under demanding conditions.Typical applications for the high-pressure overflow valve can be found in pump protection, hydraulics of diaphragm compressors and technical gas compression. It plays a particularly important role in hydrogen applications, CO₂ extraction processes and cryogenic high-pressure systems, where reliable pressure relief is essential. Series 493 is also used in chemical and petrochemical industrial processes and high-pressure storage.With its precise function, flexible installation and exceptional durability, the 493 series sets new standards in high-pressure protection. Companies that rely on maximum operational safety and efficiency benefit from a reliable overflow valve that works optimally even under extreme conditions.Let us advise you now – we have the relevant solution for your high-pressure application!connection types Male threadInternal pipe threadCone and ThreadMore information please go link: 493

Product informationJust like the Hygienic safety valves, these overflow/control valves are also implemented in line with the construction features of hygienic design and confirmed in tests by the DGUV Committee for Foods and Luxury Items. Depending on the use and medium, the seals are available with approvals in accordance with FDA, USP, 3-A and ADI-FREE.The valves are particularly used to control processes and systems in the food and pharmaceutical industries. Suitability of the medium ranges from air to various neutral and non-neutral vapours, gases and liquids.connection types Clamp connectionsThreaded ferrule connectionCone socketaseptic collar flange connectionAseptic collar clamp connectionAseptic-Threaded ferrule connectionAseptic grooved clamp connectionsAseptic grooved flange connectionButt weldsContainer flangeMore information please go link: 400.5

Product informationWith proportional opening characteristics and even larger setting ranges of the springs, this valve is ideally suited in cases where a stock value for various applications and set pressures is required and the valve needs to be readily available.It is designed in particular for plants in which only low amounts of expansion medium have to be discharged. connection types Internal pipe threadMore information please go link: 618
