Features

1. The spherical seal is used to increase the wear resistance, and the valve core is deeper into the valve seat, so as to maintain the tightness, and the valve core and bracket are matched with the specially designed lever. The spool is "free-floating" inside the bracket, avoiding rigid collisions when closing.

2. Effectively conserve energy, there is a water seal and lifting mechanism inside the bucket, so there is no steam leakage.
