Industrial Stainless Steel Thermostatic Steam Trap with 400℃ Max Temperature and 42 bar Pressure Range

The VYC 443, 444 and 543 are bimetallic thermostatic steam traps designed for draining condensate and venting air from steam lines, heat exchangers and tracing systems. The 443 is screwed, 444 is flanged, and 543 is a high-capacity or special version. They use a stacked bimetallic element that opens/closes based on temperature difference, providing automatic condensate discharge and air removal without mechanical moving parts.

• Bimetallic thermostatic element – no moving mechanical parts
• Automatic air venting during cold start-up
• Freeze-resistant when properly installed
• Compact and lightweight construction
• Replaceable thermostatic capsule
• Stainless steel body and internals
• High resistance to waterhammer and superheated steam
