Introduction
This valve is based on the one-free-floating-ball valve technology and has changed a single ball into three balls. The new type valve .has improved the craft and increased the stability and reliability.It can be used to drain water and block air in various kinds of hot-supply system.

1、 FUNCTION

1)、It can continuously ,automatically and completely drain the water and the hot-efficiency is high.

2)、It is airtight, with a low air-leak rate (<0.3%). Compared with the thermal-power valve, it saves more energy((decrease 30-50%).

3)、The filter net area is big and the service life is long. 5-10 times to the thermal-power valve(>16000h).

4)、Good at draining air, working steadily. No noise and better to improve environment.
