Watts 830950 – Frequently Asked Questions
1) How does the Watts 152A 830950 regulator connect to my piping, and do I need adapters?
Both ends are 1 inch female NPT threaded, inlet and outlet the same size, so it threads directly onto 1 inch NPT male pipe nipples. No flange kit or union is supplied with the valve, so plan on nipples and unions at each end if you want to be able to pull the regulator for service without cutting pipe.
2) What downstream pressure can the Watts 152A steam regulator be set to?
The reduced (outlet) pressure is field adjustable from 30 to 140 psi. If your process needs a delivery pressure below 30 psi, this spring range won't get you there and you need a lower-range regulator instead.
3) Does the Watts 152A regulator come with a strainer or a pressure gauge?
No on both counts. The 830950 ships without a gauge and without an integral strainer. For a steam application you'll want a separate Y-strainer ahead of the valve to keep scale and pipe debris off the seat, plus a gauge in the downstream piping so you can actually see what you are dialing in. Budget those as separate line items.
4) What is the maximum inlet pressure on the Watts 830950 regulator?
Maximum working pressure is 200 psi, which is 14 bar. That is the ceiling for the supply side; the outlet is then set anywhere in the 30 to 140 psi band.
5) What are the internals made of on this Watts process steam regulator?
Cast iron body with stainless steel trim and a stainless steel disc. Stainless on the seating surfaces is what holds up to steam service and wet condensate; the iron body is not supplied with a corrosion resistant coating, so it is meant for enclosed mechanical room piping rather than a corrosive or washdown environment.
6) Can I use the Watts 152A on domestic water instead of steam?
It is built as a process steam pressure regulator for commercial and industrial service, with an iron body and no thermal expansion bypass. For potable water service on a building supply you want a water pressure reducing valve with a bronze or lead-free body, not this one.
7) Is there a minimum temperature rating on the Watts 830950 regulator?
Rated down to 33 degrees F (0.5 C), essentially just above freezing. That matters for an outdoor or unheated pit install: the valve should not be left where the line can freeze, so heat trace or insulate if the pipe run sees winter ambient.
