Säkerhetsventiler (Safety Valve 361 – Spring Loaded, Closed Bonnet)
SAFETY VALVES – SPRING LOADED HIGH-EFFICIENCY – Series 361 with closed protective bonnet and open lift housing. Valve head is liftable. Force is transmitted centrally at the valve head. 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.
Säkerhetsventiler (Safety Valve 360 – Spring Loaded, Gas-Tight)
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.
