Steam Pressure Regulator 1/2 in
The Watts 152A is a process steam pressure regulator built for medium-capacity piping systems. It suits maintenance teams and plant engineers who need reliable downstream pressure control on 1/2 inch FNPT lines. The iron body handles saturated steam service up to 300 degrees F. It is not for buyers who need an integrated strainer or larger pipe diameters.
Adjustable Range 30 to 140 psi
The regulator adjusts outlet pressure from 30 to 140 psi while the body withstands a maximum inlet pressure of 200 psi. This range covers typical low-pressure steam heating and process loops. Systems requiring pressure settings above 140 psi or below 30 psi will need a different spring kit or valve model.
Iron Body 300 Degrees F Max Temp
The iron construction tolerates steam temperatures up to 300 degrees F at the rated pressure limit. With an overall height of 8-15/16 in and length of 6 in, the unit fits standard piping envelopes. No strainer is included, so upstream filtration must be provided separately to protect the valve seat from debris.

Questions about this item
Will the 1/2 in FNPT connections fit the iron piping I already have in place?
The regulator uses 1/2 in FNPT threads, matching standard iron pipe of the same nominal size so it threads directly onto existing fittings without adapters.
How can I verify the regulator is holding the set pressure once installed?
After adjusting within the 30 to 140 psi range, watch a downstream gauge; steady needle at the chosen setting and no leakage at the valve seat confirm correct operation.
Does the package include a strainer or pressure gauge, or must I supply them?
The unit ships as the regulator body only; no integral strainer is fitted and no gauge is included, so both must be purchased separately if required.
