401-SH 501-SH Series Inverted Bucket Superheated Steam Traps

Vertical installation (bottom inlet, top outlet) Maximum pressure difference 105 bar, maximum displacement up to 430 kg/h

 

Features

401-SH/501-SH series inverted bucket superheated steam traps are specially designed to overcome various unfavorable factors such as overheating, high pressure and low load.

In order to make the steam trap work properly under extremely harsh working conditions, the valve adopts a unique inverted bucket type steam trap with a water collection chamber. The water collection chamber collects enough condensate to ensure that the water seal can be maintained during the entire discharge cycle. The small cup in the water collection chamber can float up and down at the side steam pipe mouth. When the condensate rises, it seals the steam inlet pipe. The condensate flows into the valve. Since the water collection chamber collects the condensate and allows steam to flow in from the bottom of the inverted bucket, the discharge valve is tightly closed during the water collection period, and there is no dripping phenomenon.

Installation Recommendations

Usually, under superheated, high pressure and low load conditions, only a small amount of condensate is produced in the header and trap. Therefore, choosing the appropriate size of the pipe and header is the key to the correct use of the Ouwei superheated steam trap.
