1.Spherical seal design enhances wear resistance, with the valve core seating deeply into the seat to ensure reliable sealing. The valve core and bracket are matched with a specially designed “super lever,” allowing the core to float freely within the bracket to effectively absorb impact and avoid rigid collisions during closure.

2.Energy‑efficient design with an internal water seal and lifting mechanism inside the bucket, effectively preventing steam leakage and minimizing thermal energy loss.

3.An overflow vent at the top of the bucket effectively prevents steam lock and air binding (non‑condensable high‑temperature air can also be discharged).

4.Capable of withstanding high backpressure (up to 90%) and resistant to water hammer.

Application: Suitable for steam conveying pipelines and medium‑low pressure steam heating equipment.
