Safety valves protect all kinds of plants from impermissible overpressure. They prevent persons, the environment and investments from being damaged. As they form the last link in the safety chain their perfect function must be ensured. The requirements for development, design, production and quality management arecorrespondingly high.
The quality management which is certified by many organisations accompanies all stages of development, design and production.
The quality of the castings fulfils the requirements of DIN 1690 Part 10. In cooperation with the foundry each pattern is optimised before series release in order to prevent defects reliably. Solidification simulations are performed with the aid of 3D CAD design data. There is a prototype file for every pattern.
The welded seams are tested to the applicable standard (AD 2000, TRD, ASME). Welding work is performed by TÜV and ASME approved welders.
The spring is the key component ensuring the correct function of the safety valve. All relevant international standards are observed in its design and dimensioning.
Production: All individual parts are manufactured on modern machining centres and CNC lathes. This ensures dimensional conformity and a high surface quality.
The valve assembly is order-driven, in accordance with the customer's requirements. The safety valves are free of non-ferrous metals, asbestos and silicone; "oil and grease free" versions are optional available if required.
