功能简述Function description

结构紧凑,可选择燃气出口

With compact design, the gad output is optional

可动永磁铁式燃气比例阀

Gas proportional valve with pemanent magnet

由两个电磁截止阀和一个比例调节阀组成

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

两道控制开关,更加安全可靠

Use double switches to be safer

比例阀异常断电时可自动关阀

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

使用用途:适用于额定热负荷不超过50kW的燃气热水器和燃气采暖热水炉

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