功能簡述Function description

結構緊湊,可選擇燃氣出口

With compact design, the gad output is optional

可動永磁鐵式燃氣比例閥

Gas proportional valve with pemanent magnet

由兩個電磁截止閥和一個比例調節閥組成

It is made up of two cut-off solenoid valve sand an on-off proportional valve

兩道控制開關,更加安全可靠

Use double switches to be safer

比例閥異常斷電時可自動關閥

When the power of proportional valve is disturbed,the valve will be closed automatically

使用用途:適用于額定熱負荷不超過50kW的燃氣熱水器和燃氣采暖熱水爐

Can be used in gas water heater&gas boiler whose nominal heat loading is ≤50KW
