Watts 67452 – Frequently Asked Questions
1) What size and thread does the Watts 0067452 radiator angle valve take on the supply side?
The inlet on the Watts RA-1-AP angle valve is 1 inch female threaded, IPS thread (25 mm metric equivalent). So it threads straight onto 1 inch iron pipe size male thread coming off the steam riser or branch, no adapter needed.
2) How does this Watts radiator valve connect to the radiator itself?
The outlet is a 1 inch union joint. That union is what lets you break the connection and pull the radiator without cutting pipe or unthreading the valve from the riser, which is the main reason you use a radiator supply valve here rather than a plain angle stop.
3) Can I use the Watts 0067452 on a low pressure steam system?
Yes. It is rated to 15 psi maximum steam, which covers typical low pressure residential and commercial steam heating. On hot water service the rating is 60 psi. Anything above those numbers needs a different valve.
4) Will this work on a hot water radiator, or is it steam only?
It handles both. The RA-1-AP is rated 15 psi on steam and 60 psi on water, so it serves a one pipe steam radiator or a hydronic hot water radiator, as long as your system pressure stays under 60 psi.
5) Should I order an angle valve or a straight valve for my radiator?
Angle pattern is what you want when the supply pipe comes up out of the floor and the radiator tapping faces the wall, which is the common one pipe steam arrangement. The Watts 0067452 is an angle body. If your supply runs horizontally in line with the radiator tapping, a straight pattern valve is the correct choice instead.
6) Do I need a separate union or nipple to hook this valve to the radiator?
No separate union is required. The outlet is already a union joint, so the valve carries its own half of the connection. You will still need whatever spud or tailpiece your radiator tapping calls for on the radiator side.
7) Is the Watts 0067452 body brass or bronze, and does that matter for steam?
Bronze body. For steam and condensate service that matters, since bronze holds up to the wet and dry cycling in a steam riser better than plated pot metal trim valves do.
8) What is the Watts part number for the 1 inch bronze steam radiator angle valve?
Order it as Watts 67452, series RA-1-AP. It is a 1 inch radiator supply valve with a female IPS inlet and a union outlet.
