Watts 0036051 Thermostatic Steam Trap 25 Psi 3/4 Inch

Product Description

The WATTS 0036051 is a two-port, straightaway thermostatic steam trap designed for low-pressure and vacuum steam heating systems. Built from cast iron, it handles a maximum working pressure of 25 psi and a maximum temperature of 406 degrees F. The trap connects via threaded 3/4-inch pipe fittings and delivers a condensate capacity of 858.7 pounds per hour. It separates condensate and air from live steam, discharging them automatically to maintain efficient system operation. Licensed plumbers and HVAC pipefitters install this type of trap during new construction and retrofit work on hydronic and steam distribution systems.

This trap is suited for a range of low-pressure steam and vacuum heating applications. Typical installation points include radiators, convectors, fin pipes, drip points, unit ventilators, and air vents. The straightaway port configuration allows inline installation without redirecting the pipe run, which simplifies retrofits in tight mechanical spaces. At 17.4 pounds, the cast iron body is built for durability in demanding heating plant environments.

Key Features

• Thermostatic trap operation automatically discharges condensate and air while holding live steam
• Cast iron body rated to 25 psi maximum working pressure
• Maximum operating temperature of 406 degrees F
• Condensate capacity of 858.7 pounds per hour

• Suitable for radiators, convectors, fin pipes, drip points, unit ventilators, and air vents

Compatibility

Designed for use on low-pressure and vacuum steam heating systems including radiators, convectors, fin pipes, drip points, unit ventilators, and air vent applications where a threaded 3/4-inch thermostatic steam trap is required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with steam system piping and applicable codes such as the International Plumbing Code. Shut down the steam system and allow all pressure to equalize to zero psi before removing or installing any trap. Verify that pipe thread connections are properly sealed with appropriate thread sealant rated for steam service. Inspect strainers and associated piping for scale or debris before placing the trap in service.
