Watts 1/2 LF263A 10-125 Water Pressure Regulator Valve

SKU CH-0YXG-Z05DT MPN 1/2

Reduces incoming water pressure to an adjustable 10-125 psi range for residential and commercial plumbing systems

  • TypeDrain Components
  • Adjustable 10–125 psi range protects plumbing from pressure spikes
  • Brass body resists corrosion for long service life
  • 300 psi maximum rating handles demanding supply lines
  • 140 °F temperature limit suits hot-water systems
  • ¼ in gauge port allows easy pressure monitoring

Pressure Regulator for Commercial

The Watts LF263A valve controls incoming water pressure on a 1/2 inch line. It is built for commercial and residential supply systems where pressure must stay within a set range. The brass body handles a maximum working pressure of 300 psi and a maximum temperature of 140 degrees F. Adjustment spans 10 to 125 psi to suit varied site requirements.

Brass Body with FIP Connections and Gauge Port

The regulator uses female iron pipe threads on both inlet and outlet for direct mounting on standard 1/2 inch pipe. A 1/4 inch gauge port is included for monitoring downstream pressure without extra fittings. Brass construction resists corrosion in potable water applications. The compact length of 2 1/8 inches and height of 4 3/8 inches fits tight service spaces.

Replaces Fixed-Restriction or Failed Regulators

Install this valve when an existing regulator no longer holds pressure or when a simple restrictor cannot adapt to changing supply conditions. The adjustable range lets you match pressure to fixture needs without swapping cartridges. It is not suited for lines larger than 1/2 inch or for systems requiring pressure settings above 125 psi.
