Watts LF263A 3-50 1/4 – Frequently Asked Questions
1) What pipe size and thread does the Watts LF263A 3-50 pressure regulator connect to?
Both ends are 1/4 inch female NPT on the LF263A. Inlet and outlet are the same size and type, so it drops inline on 1/4 inch threaded pipe or tubing adapters without a reducing bushing.
2) What outlet pressure can I set the Watts LF263A 3-50 to, and what does it come set at?
Adjustment range is 3 to 50 psi (0.2 to 3.4 bar), and it ships preset at 15 psi (1 bar). If your equipment needs something other than 15 psi, plan on adjusting it at startup with a gauge on the downstream side.
3) Can I use this small Watts regulator on potable drinking water lines?
Yes. The LF263A is built with a lead free brass body and lead free brass trim, which is what makes it acceptable for potable water service. The sealing disc is Buna-N.
4) What is the maximum inlet pressure and temperature the LF263A can handle?
Rated to 300 psi (20.7 bar) maximum working pressure and 140 degrees F maximum operating temperature, with a minimum temperature of 0 degrees F (-18 C). The 140 F ceiling means it is a cold water device; do not put it on a hot water supply or a recirculation loop.
5) Is a 1/4 inch LF263A the right regulator for a whole house or building water service?
No. At 1/4 inch NPT this is a small point-of-use regulator, sized for equipment feeds, instrument lines, ice makers, humidifiers, coffee and beverage gear, and similar low-flow branches. A house or building service needs a full-size main water pressure reducing valve matched to the service line, typically 3/4 inch or larger.
6) What does 3-way mean on the Watts LF263A regulator, and does it come with a gauge?
It is a 3-way body with gauge tapping, so there is a port for a pressure gauge in addition to the inlet and outlet. The gauge itself is a separate item, so order one with a matching thread if you want to read the reduced pressure at the valve.
7) Does the LF263A include a strainer or thermal expansion bypass?
No on both counts. The LF263A has no integral strainer and no thermal expansion bypass. On dirty or older piping, put a separate inline strainer upstream to keep debris off the seat, and if the system is closed with a water heater, handle expansion with a separate tank or bypass device.
8) What part number do I order for the Watts 1/4 inch 3-50 psi lead free regulator?
Order it as Watts LF263A 3-50 1/4, in the LF263A series. Watts also carries it under part number 9821.
