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

2.A water seal and lifting mechanism are integrated inside the bucket, effectively preventing steam leakage and minimizing thermal energy loss.

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

4.Capable of withstanding high backpressure and resistant to water hammer. It is also equipped with a 360° swivel joint and built‑in strainer for easy installation and cleaning.

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