Free Float Ball Steam Traps for Efficient Condensate Removal

PN16 / PN25 / PN40, sizes 1/2″ to 8″ (DN15~200mm), available in cast iron GG25, ductile iron A536, cast steel WCB, stainless steel CF8 and CF8M per GB/T13927-2008.

Overview

Free float ball steam trap is one of the most advanced traps, because it is normally discharged timely of condensed water in the pipelines and heating equipment. This trap has an extensive application in petroleum, chemical industry, light textile, printing, pharmacy, paper making, foods and mines. Flowspec Luokai can manufacture and supply the free float ball steam trap according to GB/T13927-2008 with sizes of 1/2″ ~ 8″ (DN15~200mm).

1. Features

Stable discharge of water with large amount, small rate of steam leakage, high rate of black pressure.
The main part hollow free-ball of steel is finely ground in the trap.
The structure of stainless steel provides the ability of anti-corruption and longer service life.
