Vent Valve VAN

The VAN vent valve is for venting the area between the main shut-off valve and the block valve in the main gas train. The magnetic relief valve VAN is designed to monitor gas valves for tightness used in conjunction with a visual discharge unit. It enables the purging of excess or leakage gas. The magnetic relief valve VAN is open when it is de-energized.

Features

• Open when de-energized
• Connection flanges for pipes up to DN 50
• Suitable for a maximum inlet pressure of 500 mbar (7 psig)
• Space-saving installation thanks to compact dimensions
• Quick closing, quick opening
• Check indication by blue LED
• Position indicator with visual indicator
• EC type-tested and certified

	Applications Click on images for close-up view. 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. 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) 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.
