Features

1. Advanced SCCV closing system, spool bracket and specially designed "super lever" match. The spool is "free floating" in the spool bracket, avoiding rigid collisions when closed.

2. 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 exhaust hole, 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%).

5. Water shock resistance.

6. All internals are fixed on the valve cover for easy online maintenance.

Use: low pressure and low steam condensate flow equipment or steam pipe network. It is widely used in petroleum, chemical industry, metallurgy, paper making, medicine, food and other industrial steam equipment, especially for small steam equipment in heat tracing pipelines.
