Watts 152A-030100 2 – Frequently Asked Questions
1) How does the Watts 152A steam pressure regulator connect to 2 inch pipe?
Both ends of the Watts 152A-030100 2 are 2 inch female threaded, inlet and outlet alike. So it threads straight onto 2 inch male NPT nipples or male adapters, no flanges and no companion gaskets. If your line is copper or welded steel, you'll need threaded transition fittings on each side to land it.
2) What downstream pressure can I set this Watts regulator to?
The reduced (downstream) pressure is field adjustable from 30 to 100 psi. If your process needs delivery below 30 psi, this is the wrong range and you want a lower-range version of the 152A. Maximum working pressure on the valve is 200 psi (14 bar), so inlet steam has to stay at or under that.
3) Can I use this Watts 152A regulator on potable water?
No. The 152A-030100 2 is a process steam pressure regulator with an iron body, and it is not lead free. Keep it on steam and non-potable process service. For drinking water you need a lead-free rated water pressure reducing valve instead.
4) Does the Watts 152A regulator come with a pressure gauge?
No gauge is supplied with the 152A-030100 2. Since you have to dial the downstream setting somewhere between 30 and 100 psi, plan on a separate steam-rated gauge with a siphon (pigtail) in the outlet piping, plus a gauge tapping if your pipe run doesn't already have one. The valve ships as a kit assembly.
5) Will this Watts regulator meet Buy American requirements on a federal job?
It will not. The 152A-030100 2 is listed as not Buy American Act compliant, so on federally funded work with a BAA or Build America clause you'll need a domestically sourced steam regulator instead.
6) What is the exact part number to order this 2 inch Watts steam regulator?
Order it as Watts 152A-030100 2. That designation carries the 2 inch size and the 30 to 100 psi reduced pressure range together, so quoting just "152A" will not pin down the range a distributor needs.
7) What is the minimum temperature rating on the Watts 152A steam regulator?
Minimum rated temperature is 33 F (0.5 C), essentially just above freezing. In practice that matters for unheated mechanical spaces and outdoor pits: the body and diaphragm chamber are not rated for freezing service, so an idle line in a cold space needs to be drained or heat traced.
8) Is the Watts 152A a standard single-stage steam regulator or something specialized?
Valve style is standard, a conventional single-body iron pressure regulator for process steam service rather than a specialty or pilot-operated design. It reduces an upstream supply of up to 200 psi to an adjustable 30 to 100 psi downstream.
