Watts 2.5 S1115,THD 2-1/2" Pressure Reducing Valve, Ductile Iron, NPT

The Watts 2.5 S1115,THD is a 2-1/2" angle-pattern pilot-operated pressure reducing control valve with NPT connections. It features a ductile iron body. Rated to 200 psi.

This 2 1/2 inch, model S1115 THD, ACV pressure reducing control valve is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates. The valve has an adjustable range of 20-200 psig. SentryPlus Alert® technology provides intelligent pressure monitoring and notifications using integrated sensors, and integrates with the Sensor Control Monitor to deliver maintenance alerts through BAS via RS-485 Modbus or the Nexa® platform over Wi-Fi.

Features

• Threaded
• Maximum 400 psig rated
• Angle pattern valve body
• Integrates with the Sensor Control Monitor to deliver maintenance alerts to BAS via RS-485 Modbus or the Nexa platform by Wi-Fi connectivity
• 20-200 psig Adjustable range

Common Questions

What is the maximum working pressure?

This unit is built as THD (NPT Threaded) and is rated to 200 psi. Threaded and grooved bodies on this platform carry a higher working pressure than 150# flanged bodies, so do not assume a flanged datasheet applies here.
