 Sanitary Steam Traps > Mark 93 Series



CGDM Series The Mark 93 is a thermostatic steam trap designed specifically for use in clean steam systems demanding that sanitary conditions be maintained. It features a 20 Ra internal finish, and a self-draining design, to minimize the possibility of medium entrapment and bacterial growth.

The improved configuration of the MK93 has been specifically designed to provide higher flow rates at low pressures and low subcooling levels. In lab testing, the MK93 consistently exhibited excellent flow rates at subcooling levels of only 5° (2,8°C) or less.

Two designs are featured in the MK93 Series – the standard MK93 good for differential pressures up to 65 psi (4,5 bar), and the MK93HP, for differential pressures ranging from 50-90 psi (3,4–6,2 bar). Both designs are rated to 90 psi (6,2 bar) operating pressure (hydrostatically tested to 450 psi (31 bar)) but provide best performance when used within their differential pressure ratings.

During start-up, the bellows assembly is fully open to discharge all air, non-condensable gases and cool condensate. The heat of the entering steam causes the element to expand, closing the valve. As condensate accumulates in the body, the element cools, causing the bellows/stem tip to retract. The line pressure compresses the element to open the valve and discharge condensate.
