Watts 0830945 Regulator

The Watts 0830945, specifically the 152A-1-128, is a high-sensitivity process steam pressure regulator engineered for medium-capacity applications where maintaining a precise discharge pressure is critical. Built with a rugged iron body and 1-inch FNPT threaded connections, this valve is a standard in boiler rooms for managing steam lines feeding autoclaves, steam tables, sterilizers, and vulcanizers. It handles an initial supply pressure of up to 200 psi and utilizes a 10-30 psi adjustable range spring, allowing technicians to fine-tune downstream pressure with extreme accuracy. The stainless steel strainer and internal trim come standard, protecting the valve seat from scale and debris common in aging steam systems. Designed with the contractor in mind, the Watts 152A facilitates in-line serviceability; the disc and stem assembly are accessible via a large bottom plug, meaning you won’t have to break the piping to perform routine maintenance or clear a clogged screen. This model replaces older 152A-1-128 and 152A-M3-1-10-30 configurations, ensuring a drop-in fit for existing industrial and commercial steam process headers.

• Full Flow Performance: Responds rapidly to reduced pressure changes to maintain maximum volume with minimal pressure drop across the 1-inch orifice.
• Reduced Vibration: Features an integrated sensitivity adjuster to stabilize flow and eliminate chatter in high-velocity steam applications.
• Industrial Durability: Equipped with a laminated metal diaphragm and stainless steel disc for long-term resistance to high temperatures up to 400°F.
• Simplified Maintenance: The 152A series design allows for complete internal inspection and part replacement without removing the valve from the line.

Is the Watts 0830945 suitable for potable water applications?
No, this regulator is specifically designed for non-potable process steam and liquid applications. It is not compliant with lead-free requirements for human consumption systems.

Can the outlet pressure be adjusted outside the 10-30 psi range?
This specific model is equipped with a spring designed for the 10-30 psi window. For higher or lower pressure requirements, a different spring or regulator model must be used to ensure calibration accuracy.

What is the maximum temperature rating for this iron body regulator?
The standard 152A series with iron construction is rated for temperatures up to 400°F (204°C) at a maximum working pressure of 200 psi.
