Xylem 402012 Hoffman 17C Thermostatic Steam Trap 1" Angle 25 PSI

The Xylem-Hoffman Specialty 402012 Series 17C thermostatic steam trap is designed to provide effective steam elimination and condensate management in HVAC systems. This balanced pressure thermostatic steam trap is ideal for institutional, commercial and residential heating system applications such as schools, hospitals, apartment buildings, homes or others where low or moderate water hammer may occur.

Key Features:

• 1" angle connection with 25 PSI maximum operating pressure
• Balanced pressure design using a special bellows diaphragm that opens in response to pressure and temperature to discharge air and condensate, and closes against passage of steam
• Brass body construction with stainless steel valve disc
• Maximum temperature rating of 267°F
• Opens at 10° to 30°F below saturated steam temperature for existing pressure
• Capacity based on 40°F subcooling

The trap is normally open allowing fast venting of air during start-up, with cold condensate draining through the trap. During operation, the thermostatic element finds an equilibrium point to drain condensate approximately 10° to 30°F below saturation at continuous flow. This trap is small, simple in construction, size and weight, and has adequate capacity for various applications, especially in low-pressure heating systems.
