Thies Armatur GmbH & Co KG products

Safety valve to satisfy safety requirements in heating systems with flow temperatures of 120°C according to EN 12828. THIES High-efficiency Safety Valves satisfy the German requirements of the following specifications: UVV- “Pressure Vessels“, AD Specification A 2 „Safety Valves“, the Technical Rules for Steam Boilers (TRD), SR Safety Valves and EN 12828.

356 / 357 type approval (D/G) (steam/gas), spring loaded for steam and gas and other heating systems according to EN 12828 / TRD. As safety valves for steam, gases and hot water in pressure vessels and steam boilers. Application also in accordance with DIN 4752.

Safety valves for blowing-off liquid from fixed pressure vessels, subject to the condition that no evaporation occurs. Also suited to district heating systems. If the liquid to be blown off does not have similar properties to the liquid (water) used in the valve testing procedure, then the properties of the liquid, in respect to chemical aggressiveness or sticking tendency, must be taken into account in the acceptance testing of the pressure vessel. THIES High-efficiency Safety Valves meet the requirements of the German Pressure Vessel Safety Regulations and AD Specification A 2 „Safety Valves“.

These safety valves are for blowing-off saturated steam from pressure generators. THIES-Diaphragm High-efficiency Safety Valves meet the following German requirements: the AD Specification A 2 for „Safety Valves“, the Technical rules for steam boilers (TRD 721), the Safety Valves Code according to EN 12828.
