Design Features:
1. All internal moving parts are made of stainless steel, which is resistant to wear and corrosion.
2. As the steam cannot reach the valve seat hole sealed by water, there is no steam loss and high efficiency and energy saving.
3. The floating bucket is inverted, it will not be damaged or crushed, not afraid of water hammer, and has a long life.
4. The top of the inverted barrel is equipped with an exhaust hole, which can continuously exhaust air without air blocking.
5. It is not affected by back pressure and can work normally under high pressure.
6. Reliable work, only two moving parts, lever and inverted barrel, will not cause jamming.
7. The valve seat and valve clack are on the top of the valve, and the valve clack can allow dirt to pass through during the switch, without the influence of dirt disturbing.
