Kromschroder 88000051 VAS350R/NQ gas valve for safeguarding and controlling the air and gas supply to gas burners and gas appliances. Kromschroder 88000051 VAS350R/NQ gas solenoid valve use in gas control and safety systems in all sectors of the iron, steel, glass and ceramics industries, also in commercial heat generation, such as the packaging, paper and foodstuffs industries. Kromschroder VAS350R/NQ 88000051 compact gas unit for systems up to SIL 3 pursuant to EN 61508 and PL e pursuant to ISO 13849. EU certified pursuant to Directive Gas Appliances Directive 2009/142/EU (valid until 20 April 2018) in conjunction with EN 13611 and EN 161. Krom schroder 88000051 VAS350R/NQ gas control unit technical data: Size 3 EU certified Inlet: DN 50 (2'') Outlet: DN 50 (2'') Rp internal thread Quick opening, quick closing With flow adjustment Mains voltage: 120 V AC, 50/60 Hz Electrical connection: M20 cable gland Accessories, right: 2 screw plugs Accessories, left: 2 screw plugs Kromschroeder VAS350R/NQ 88000051 gas control block function: Kromschroder VAS350R/NQ 88000051 gas valve closed when it 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 valve discs upwards. Kroms chroder VAS350R/NQ 88000051 gas solenoid valve opens. The double valve seat means that the forces from the inlet pressure divided almost equally between the two valve seats. Closing: disconnect Kromschroder VAS350R/NQ 88000051 from the electrical power supply. The blue LED goes out. The armature pressed into its initial position by the closing spring. The gas solenoid valve closes within 1 s. The strainer in the inlet of the gas solenoid valve prevents deposits of dirt particles on the valve seats. The pressure loss through the strainer is very low.
