Safety valves

A safety valve is a valve which automatically, without the assistance of any energy other than that of the fluid concerned, discharges a quantity of the fluid so as to prevent a predetermined safe pressure being exceeded, and which is designed to reclose and prevent further flow of fluid after normal pressure conditions of service have been restored. Ramén Valves supply safety valves from the German brand Goetze.

The safety valves of this series have been awarded full approval for vapours and gases as well as for liquids. All components of the valve are specially cleaned during the production process and are thus oil- and grease free in accordance with DIN EN 12300. Because of this every valve is suitable for use in systems using oxygen and is accordingly marked. The use of 1.4404 and 1.4408 high-alloy stainless steels renders the safety valves particularly resistant to extremely cold temperatures. For the use with gases that are in contact with food an FDA-compliant sealing material has been used.
The valve setting and seat insert are separately sealable which makes unauthorised adjustments easily noticeable. Overpressure from 0.2 bar up to 70.0 bar is purged safely with a consistently high level of performance.

This pressure reducing valve is an alternative to the larger versions, in cases where only small flow volumes are required or the medium in question is compressed air. With an outlet pressure of max. 50 bar the pressure reducing valve is used, for example, to control the starter air on ships. It goes without saying, that it holds all the necessary marine approvals of the various bodies such as Germanischer Lloyd etc. This valve is used in many industrial applications particularly for compressed air and neutral gases.

A particularly robust pressure reducing valve in all-metal design, which has proven itself not only in drinking water applications but also in harsh operating conditions in industrial applications or in cases of fluctuating environmental temperatures. This pressure reducing valve is also suitable for hot water applications. Stability and reliability: The set outlet pressure at zero-usage is held constant even in the case of greatly varying inlet pressures.

New applications can now be covered by Goetze’s well-proven, robust pressure reducing valve with threaded connections now that they have extended their gunmetal series 681 to include a stainless steel version. The new 481 offers all the advantages of the 681 – while at the same time withstanding very critical and aggressive media and environments. Additional outlet pressure ranges of 0,5 to 2 bar and 5 to 15 bar make this valve suitable for an even wider range of applications.

By means of an external setting mechanism this valve can be set or adjusted by the operator during operation. The closed, gastight version with large spring ranges offers a wide range of application possibilities. This valve is also widely used as an overflow valve in applications where the plant pressure often changes. Due to its versatility and large spring ranges, this valve can be highly recommended as a stock item.
