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.

3. The top of the bucket is equipped with an overflow exhaust hole, which can effectively prevent steam gas lock and air blockage (non-condensable high-temperature air can also be excluded).

4. It can withstand high back pressure, resist water hammer, and is designed with a 360-degree rotary joint and built-in filter, which is easy to install and clean.

Application: It is suitable for medium and low pressure and medium and low flow steam pipeline heating equipment.
