Leser Clean Service Safety Valves

Safety valves are the last link in the safety chain, their perfect function must be ensured. The requirements for development, design, production and quality management are correspondingly high.

The quality of the castings fulfills the requirements of DIN 1690 Part 10. In cooperation with the foundry, each pattern is optimised before series release so as reliably to prevent defects. 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 hte applicable standard (AD, TRD, ASME). Welding is performed by TÜV and ASME approved welders.

The spring is the key component ensuring correct function of the savety valve. All relevant international standarts 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.

Valve assembly is order-driven, in accordance with the customer's wishes. The safety valves are free of non-ferrous metals, asbestos and silicone; "oil and grease free" versions are availible as required.

Quality management accompanies all the stages of development, design and production, and the system is certified by many organisytions.
