Watts 0009898 Regulator

The Watts 0009898 is a high-performance 1/2" pilot regulator, specifically the lead-free LF263AP model designed for precise pressure control in demanding HVACR and commercial water systems. This direct-acting, diaphragm-actuated valve is engineered to reduce high upstream inlet pressure to a constant, reliable downstream setting, adjustable from 20 to 175 psi. As a veteran-grade lead free water pressure regulator, it features a rugged forged brass body and an oversized orifice to prevent clogging and ensure consistent flow. This model serves as the official updated replacement for older units, including the 0335060, 263AP-1/2, and LF263AP-20-175-1/2. Built with a Buna-N stainless steel disc and a reinforced Buna-N diaphragm, it handles temperatures from 0°F to 140°F and maximum working pressures up to 300 psi. Whether integrated into automatic control valve circuits or used for beverage dispensing and process applications, this Watts LF263AP regulator provides the technical reliability contractors expect.

Key Benefits:

• Lead-Free Brass Construction: Ensures full compliance with safety codes for potable water and food service applications.
• Field-Adjustable Performance: Features a tee handle adjustment for easy on-site calibration between 20 and 175 psi, factory-set at 75 psi.
• 3-Way Valve Versatility: Equipped with a 1/4" NPT side port, ideal for installing an outlet pressure gauge or plugging for standard use.
• Durable Internal Trim: The stainless steel stem and spring resist corrosion, extending the service life in harsh water conditions.
• High Flow Stability: The reinforced Buna-N diaphragm responds quickly to pressure fluctuations, maintaining a steady setpoint.

Common Questions:

How do I adjust the outlet pressure on the LF263AP?
Use the tee handle on the aluminum spring cage; turning clockwise increases the downstream pressure setpoint, while counterclockwise decreases it.

Can this regulator handle fuel oil?
Yes, the Watts 0009898 is rated for use with both water and No. 2 fuel oil, making it suitable for varied industrial process applications.

What is the purpose of the 1/4 inch side port?
This is a three-way low-pressure gauge port, allowing technicians to monitor accurate downstream pressure directly at the regulator during commissioning.
