SAFETY VALVES – SPRING LOADED HIGH-EFFICIENCY – Application: As safety valves for steam, gases and hot water in pressure vessels and steam boilers. Series 357 version with closed bonnet Liftable valve head. Force is transmitted centrally at the valve head via ball. Corrosion-resistant spindle guides ensure reliable and precise response of the valve.

SAFETY VALVES – SPRING LOADED HIGH-EFFICIENCY – Series 360, Gas-tight with closed protective bonnet and closed lift housing. 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.

Corrosion-resistant spindle guides ensure reliable and precise response of the valve. Safety valves for blowing-off liquid from fixed pressure vessels, subject to the condition that no evaporation occurs. Also suited to district heating systems.

SAFETY VALVE WITH SPRING LOADING MODEL 095 – The valve works as an automatic pressure releasing regulator activated by the static pressure existing at the entrance to the valve and is characterized by its ability to open proportional to the pressure increase. Design in accordance with “International Standard ISO 4126-1:2004 Safety Valves”. In accordance with the requirements of directive 97/23/EC. EC valve verification certified by: TÜV Internacional Grupo TÜV Rheinland, S.L. EC 0035.

SAFETY VALVE WITH SPRING LOADING MODEL 096 – The valve works as an automatic pressure releasing regulator activated by the static pressure existing at the entrance to the valve and is characterized by its ability to open proportional to the pressure increase. Design in accordance with “International Standard ISO 4126-1:2004 Safety Valves”. In accordance with the requirements of directive 97/23/EC. EC valve verification certified by: TÜV Internacional Grupo TÜV Rheinland, S.L. EC 0035.
