These traps use an inverted bucket as a float device to control the opening and closing of the plug and seat to discharge condensate. Body materials available are Cast Iron and Stainless for pressures up to 450 psig. The top-mounted discharge orifice makes them less susceptible to clogging from dirt and debris. Primarily used for drip applications but may be considered for process applications when air venting is not critical. Rugged and simple design and service life often exceeds other style traps.
