1. Advanced SCCV shut-off system, the spool, bracket and specially designed lever are matched, and the spool is "free floating" in the bracket to avoid rigid collision 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 to 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 maintain and repair.
Application: It is suitable for low-pressure and medium-low flow steam pipeline heating equipment.
