Watts 0335020 Three Way Small Pressure Regulator

Description:

The Watts 263A 1/2" (Part Number 0335020) is a three-way small pressure regulator designed for general-purpose pressure regulation in water and No. 2 fuel oil piping systems. Constructed with a forged brass body, NPT female inlet and outlet connections, a 1/4-inch three-way low-pressure gauge port, reinforced Buna-N diaphragm, stainless steel disc, aluminum spring cage, and tee-handle adjustment, the regulator provides accurate and stable downstream pressure control. Its oversized orifice design makes it particularly suitable for low-flow applications requiring reliable pressure regulation and consistent performance. The Series 263A has a maximum working pressure of 300 PSI and has been discontinued in favor of the LF263A lead-free series.

Applications:

The Watts 263A 1/2" Pressure Regulator is commonly used in beverage dispensing equipment, paint spraying systems, ice cube machines, humidifiers, drinking fountains, laboratory equipment, small process water systems, fuel oil piping systems, commercial appliances, and industrial fluid handling installations where precise pressure regulation, equipment protection, and stable downstream pressure are required for efficient operation.
