Xylem 401536 1/2" Angle Thermostatic Steam Trap 25 PSI

The Xylem 401536 is a Series 17C balanced pressure thermostatic steam trap designed for efficient condensate removal in low-pressure steam heating systems. This angle pattern trap features a 1/2" NPT connection and is rated for 25 PSI differential pressure with a condensate capacity of 880 pounds per hour.

Key Features:

• Cast bronze body construction provides excellent resistance to moderate water hammer and chemical attack
• Stainless steel Dura-Stata thermostatic module for reliable operation and easy field replacement without disturbing piping connections
• Balanced pressure bellows diaphragm design opens in response to pressure and temperature to discharge air and condensate while closing against steam passage
• Normally open during start-up for fast air venting and rapid system warm-up
• Operating temperature range: opens 10° to 30°F below saturated steam temperature at existing pressure
• Compact angle pattern design reduces installation space requirements
• Model 17C-A-2-25 configuration

During operation, the thermostatic element expands when steam is present to close the trap, and contracts when cooler air or condensate is present to open the trap and allow drainage. This balanced pressure design helps reduce start-up times and improve overall system efficiency in residential and commercial steam heating applications.
