Application examples Relief valve with two gas solenoid valves and tightness control Whenever no hydrogen is needed for the annealing process (e.g. in the case of an annealing bell), the gas solenoid valves VAS and the magnetic relief valve VAN are disconnected from the electrical power supply. The VAN opens. Under high pressure, nitrogen can now get between the two gas solenoid valves VAS. This prevents hydrogen from flowing into the furnace. Replacement possibilities VAN 15 -40/32 is to be replaced by VAN 110-250. Flow rate Tightness control TC 2 checks the gas solenoid valves VAS and the...
