WPN-160
Bi-Metallic Steam Traps are use in steam tracing, steam main drips and non-critical process equipment. They can be used in outdoor applications that are subject to freezing. Bi-Metallic Steam Traps will back up some condensate into the system and should only be used when this condition is permissible. To learn and see more about Thermodynamic Steam Traps, please visit the Bi-Metallic section.

DRIP, TRACING: WPN-160 series are available in sizes 1/2" - 1" and pressure up to 1620 psig. Also the max diff. pressure up to 1600 psi. They are extremely robust and reliable, making them a suitable choice forsuperheated steam, high pressure applications, as well as outdoor applications that are subject to freezing.

Product Overview
DRIP, TRACING: WPN Series Bi-metallic steam traps are used in steam tracing, steam main drips and non-critical process equipment. They are extremely robust and reliable, making them a suitable choice for high pressure applications as well as outdoor applications that are subject to freezing. They are used in systems where a quick discharge of air, non-condensable gases and large quantities of cold water need to be discharge at start-up.
Features
• Excellent for high-pressure and superheated steam applications
• Freeze-proof and resistant to waterhammer
• Suitable for superheated steam
• In-line repairable
• Trap can be welded into line
How It Works
When the system is cold, the trap is fully open; discharging air and cold condensate. When the bi-metallic plates inside the trap heat up, they expand; pulling the seat closed and restricting flow. Prior to steam temperature being reached, the trap shuts off tightly. Cooler temperatures cause the seat to open further. Therefore, trap capacity will increase when colder condensate is in contact with the Bi-metal element. Trap capacity is therefore given at different temperatures below saturated steam temperature.
