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, bracket and specially designed lever are matched. The spool is "free-floating" inside the bracket, avoiding rigid collisions when closing.

2. Effectively save energy, there is a water seal and lifting mechanism in the bucket, and there is no steam leakage.

3. There is an overflow exhaust hole on the top of the bucket, which can effectively prevent steam vapor 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 easy to install.

Application: Suitable for medium and low pressure and medium and low flow steam heating equipment.
