Features

1. The spherical seal is used to increase the wear resistance, and the spool is deeper into the seat, thus maintaining the seal. The spool and bracket are matched with the specially designed "super lever". The spool is "free floating" in the spool bracket, avoiding rigid collisions when closed.

2. Effectively save energy, 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 overflow vent, 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.ESH401 can be used in superheated steam lines with a unique double chamber design to ensure that the bucket is always water sealed during each discharge cycle to prevent steam leakage due to too little condensate water in the overheating state.

Application: Medium and low pressure and steam condensate flow equipment. It is widely used in petroleum, chemical industry, metallurgy, paper making, medicine, food and other industrial steam equipment.
