Performance / Advantages:
Continues discharging saturation condensed water without accumulation, and so get the maximum thermal efficiency.
When steam pressure changes, the ball float can adjust the opening of valve seat without influence, and so it is stable.
With automatic and manual releaser, and so its exhaust performance is good without airlock and working is smooth without noise.
Application:
By automation, speediness and continuing features, this valve is used for the steam heating equipment, condensation water recovery system and the place where needs removing condensation water at quick speed, and so stop steam leakage effectively and obtain optimum heating.
Working Principle:
By the action of buoyancy, the position of floating ball changes with the water level of condensation water and adjust the opening of valve seat automatically, continue to discharge condensation water, when the condensation water stops, the floating ball fall onto bottom by gravity, then close opening of drain valve. The opening of drain valve is below the water lever, and so the water is separated from steam automatically, and form water seal without steam leakage.

Use and Maintenance:
Confirm the valve material, pressure and check if the maximum is suitable for operation condition.
Before installation, clean the pipeline and clear away sundries.
The installation position shall be closed to heating equipment as much as possible.
Install the minimum point of pipe horizontally and the direction of flow should be the same to the label of valve.
Install steam trap for each heating equipment in case cause influence each other.
under the safe operation of system, open the valve in front of the steam trap, make it rise up to normal station slowly.
Do time-based maintenance for the normal working of steam trap.
