Watts RA-1-AP 1/2 – Frequently Asked Questions
1) Can I use this Watts radiator valve on a one-pipe steam system?
Yes. The RA-1-AP is a radiator supply valve rated to 15 psi steam, which covers residential and low pressure commercial steam service. On water it is rated to 60 psi, so it also works on a hot water radiator loop within that pressure.
2) Is the Watts RA-1-AP Buy American Act compliant for a government job?
No. The RA-1-AP is not Buy American Act compliant, so it will not satisfy a BAA or domestic-content clause on a federal or federally funded project.
3) Is the Watts RA-1-AP lead free for potable or domestic work?
The RA-1-AP is a lead free bronze valve. That matters less on a closed steam loop and more where a facility standardizes on lead free brass and bronze across the whole building.
4) Does the RA-1-AP come with the union nut and tailpiece to connect to the radiator?
The outlet is a union joint connection, so the valve is built to break at a union at the radiator rather than being threaded solid. Confirm the tailpiece thread matches the spud already in your radiator before you set it, since old cast iron radiators vary in spud size.
5) Will a bronze radiator valve hold up on old steam risers in an apartment building?
The RA-1-AP body is bronze, which is standard for steam radiator service and tolerates the wet-dry cycling in a steam riser better than plated pot metal. It is a 15 psi steam valve, so it fits typical low pressure residential and multi-family steam heat. For fleet work, all the openings take the same 1/2 inch IPS female inlet and 1/2 inch union outlet, which keeps replacements uniform.
6) What is the Watts part number for the 1/2 inch RA-1-AP angle radiator valve?
Order it as Watts RA-1-AP 1/2, Watts part number 67450. That is the 1/2 inch bronze angle pattern steam radiator supply valve in the RA-1-AP series.
