Watts 0036041 Thermostatic Steam Trap 25 Psi 1/2 Inch

Product Description

The WATTS 0036041 is a two-port thermostatic steam trap designed for steam distribution and condensate removal in hydronic and process piping systems. Built with a cast iron body, it handles working pressures up to 25 psi and maximum temperatures up to 406 degrees F. Thermostatic steam traps operate by responding to temperature differentials between steam and condensate, discharging subcooled condensate while holding live steam. This unit is installed by licensed plumbers and pipefitters in commercial and industrial steam systems where reliable condensate management is required.

The 0036041 is suited for low-pressure steam heating systems, unit heaters, heat exchangers, and process equipment using 1/2 inch pipe connections. Its two-port configuration supports straightforward inline installation in condensate return lines. The cast iron construction is appropriate for interior mechanical rooms and equipment rooms where moderate-pressure steam service is standard. This trap is a working-component replacement or new-installation part for systems requiring dependable thermostatic operation at or below 25 psi.

Key Features

• Cast iron body construction rated for steam service up to 25 psi working pressure
• Maximum operating temperature of 406 degrees F suits most low-pressure steam heating applications
• Two-port design allows straightforward inline condensate line installation
• Thermostatic operation discharges condensate based on temperature differential without requiring moving mechanical floats
• 1/2 inch pipe size fits common branch and runout connections in residential and light commercial steam systems

Compatibility

Designed as an OEM-style replacement or new-installation thermostatic steam trap for low-pressure steam piping systems using 1/2 inch pipe connections rated to 25 psi.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes. Shut down and depressurize the steam system fully before removing or installing any trap. Verify pipe thread engagement and use appropriate thread sealant rated for steam service. Inspect the condensate return line for proper pitch and drainage before commissioning the replacement trap.
