Features

1. The spherical seal is used to increase wear resistance, the spool is deeper into the seat, thus maintaining the seal, and the spool bracket is matched with a specially designed "super lever". The spool is "free floating" in the spool bracket, avoiding a rigid collision when closed.

2. Effectively save 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 provided with an overflow vent, which can effectively prevent the phenomenon of steam lock and air blockage (non-condensing high temperature air can also be excluded).

4. Can withstand high back pressure (up to 90%), water shock resistance.

Uses: Used in steam conveying pipeline and medium and low pressure steam heating equipment.
