Applications

Application for Vent Valve VAN Relief valve with two gas solenoid valves and tightness control

Tightness control TC 2 checks the gas solenoid valves VAS and the magnetic relief valve VAN for tightness.

If the gas solenoid valves and the magnetic relief valve are tight, the tightness control forwards an enable signal to the automatic burner control unit. The pilot valve output of the automatic burner control unit opens the gas solenoid valves VAS simultaneously. The burner starts.

In accordance with the Russian safety regulations PB 12-529-03, installations with a capacity of ≥ 1.2 MW must be fitted with a relief valve and tightness control.
Application for Vent Valve VAN Relief valve with 2 gas solenoid valves

A valve, open when de-energized, is designed to purge gas to a safe venting point.

For the NAFTA market, this applies for capacities of ≥ 117 kW (400,000 BTU/h)
Application for Vent Valve VAN Inert gas atmosphere for annealing processes

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.

Specifications
