Watts 0037111 Float Thermostatic Steam Trap 4 Port Cast Iron

Product Description

The WATTS 0037111 is a float and thermostatic steam trap designed for industrial and commercial steam systems. It combines a float mechanism with a thermostatic air vent to discharge condensate continuously while venting air and non-condensable gases automatically. Cast iron construction gives it the durability needed for sustained high-temperature service. Rated to 30 psi maximum working pressure with a maximum temperature rating of 406 degrees F, this trap handles demanding steam line conditions. Licensed plumbers, pipefitters, and steam system technicians are the typical installers for this type of device.

The WATTS 0037111 is suited for residential steam heating systems, commercial process steam lines, and industrial condensate return applications where reliable, continuous condensate drainage is required. The four-port design provides flexible piping configurations for a variety of system layouts. With a 1-1/4 inch pipe connection size, it fits mid-range steam distribution lines commonly found in larger commercial buildings and light industrial facilities.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber familiar with steam system codes, including applicable ASME and local mechanical code requirements. Shut down and depressurize the steam system completely before removing or installing any trap. Verify flow direction markings on the trap body and align them with the condensate flow path. Do not overtighten pipe connections; use appropriate thread sealant rated for steam service.
