Product Overview
DRIP, PROCESS: FDA400 Series thermostatic clean steam traps are used in clean steam applications such as drainage for CIP/SIP systems and various process vessels. The universal horizontal connection allows the trap body to swivel to any angle. The FDA400 Series allows for a 90 degree connection on either the inlet or outlet capable of 360 degree orientation. Available with 2°F sub-cool bellows.
• Universal horizontal connection swivels to any angle
• All wetted parts are 316L stainless steel
• Electro-polish finish of 20-25 microinches RA on internal surfaces of body
• Electro-polish finish of 25-32 microinches RA on external surfaces of body
• Operates close to saturation curve to minimize condensate back-up
• Completely self-draining in the vertical downward flow orientation
How It Works
This trap contains a welded 316L stainless steel thermal element that expands when heated and contracts when cooled. When air and sub-cooled condensate are present, the trap is in an open discharge position. When steam reaches the trap, the element expands, closing the trap tightly.
Selection / Sizing / Capacities

The Steam Trap shall be all 316L stainless steel thermostatic type with a balanced pressure bellows that operates close to saturated steam temperatures. Inlet, outlet or both connections must contain a 90° swivel arrangement capable of 360° orientation. Internal body parts shall have an electro-polish finish of 20-25 microinches RA internally and a 25-32 finish externally. The unit shall have a split-body sanitary clamp design for easy maintenance. Trap shall be completely self-draining when mounted vertically.

Note:  Capacities at 10ºF below saturation.
