Product Description
Kromschroder OR VAV 120R/NWAK Double Gas Solenoid Control Valves For Gas Burners/Boiler
Solenoid valves for gas VAS
1.A further development of the solenoid valves for gas VG and VS
2.Suitable for a max. inlet pressure of 500 mbar
3.Easy installation into a system
4.Compact design saves space Easy flow adjustment with display
5.Check indication by blue LED
6.Position indicator with integral visual indicator
6.Position indicator with integral visual indicator
7.Suitable for intermittent operation
8.Wide-ranging applications due to the modular construction
9.Higher flow rates with the same nominal size
Application
The modular design principle allows the individual compon ents of theVAS,VCS Series tobe easily assembled: e.g. quick opening, slow
opening, with proof of closure switch and visual position indicator, slow opening with attached pressure switch.
opening, with proof of closure switch and visual position indicator, slow opening with attached pressure switch.
Solenoid valves for gas VAS and double solenoid valves VCS for safe guarding and controlling the air and gas supply to gas burners and gas
appliances. For use in gas control and safety systems in all sectors of the iron, steel, glass and ceramics industries, as well as in commercial heat generation, such as the packaging, paper and foodstuffs industries.

Function
The gas solenoid valveVASis closedwhenit is disconnected from the power supply.
Opening: connect the system to the electrical power supply (alternating voltage will be rectified). The blue LED lights up. The coil’s magnetic field pulls the
armature with the attached valved is csup wards. The gas solenoid valve VAS opens. The double valve seat means that the forces from the
armature with the attached valved is csup wards. The gas solenoid valve VAS opens. The double valve seat means that the forces from the
inlet pressure are divided almost equally between the twovalveseats. Closing: disconnect theVASfrom the electrical power supply.The blue LED goes out.The armature is pressed intoits initialpositionby theclosingspring.Thegas solenoid valve closes within 1 s.
The strainerin the inlet of the gas solenoid valve prevents deposits of dirt particles on the valve seats.The pressure loss throughthe straineris very low.
VAS 1–8 . .N, VAS 1–3 . .L
The flow rate can be varied by a flow adjusting screw on the
actuator within a range from 20 to 100%. On VAS 1–3, the setting can be monitored on an indicator.
