Watts 0830918 Reg

The Watts 0830918 (Series 152A-3/4-145) is a high-performance process steam pressure regulator engineered for demanding commercial and industrial environments. This 3/4-inch FNPT steam pressure reducing valve features a rugged iron body construction and a stainless steel disc, making it the standard choice for autoclaves, sterilizers, and steam tables. Designed to handle an initial inlet pressure up to 200 psi, this industrial steam regulator provides a precise reduced pressure range of 3 to 15 psi. Its high-sensitivity design ensures immediate response to downstream pressure fluctuations, maintaining full flow volume with minimal pressure drop across the seat. As a direct Watts 152A replacement for models 152A-3/4-145 and 152A-M3-3/4-3-15, this unit integrates a built-in sensitivity adjuster to eliminate harmonic vibration often found in critical flow HVAC steam systems. The in-line serviceability allows technicians to perform maintenance or replace internals without breaking the pipe pipe connections, significantly reducing system downtime.

• Full Flow Capacity: Delivers maximum steam volume with negligible pressure drop, ensuring consistent performance for sterilizers and process lines.
• Internal Sensitivity Adjuster: Allows on-site calibration to stop valve chatter and vibration under varying load conditions.
• Stainless Steel Trim: Features a stainless steel seat, disc, and stem guide for superior resistance to wire-drawing and corrosion.
• Simplified Maintenance: The large bottom plug provides quick access to the internal strainer and disc assembly for in-line cleaning.
• Broad Compatibility: Direct drop-in replacement for legacy Watts 152A and 152A-M3 series 3/4" regulators.

What is the maximum inlet temperature for the Watts 152A?
The standard Watts 152A with an iron body and stainless steel disc is rated for a maximum operating temperature of 300°F (149°C).

Does this regulator require an external sensing line?
No, the 152A series utilizes internal sensing to manage reduced pressure, simplifying installation in tight mechanical rooms or equipment skids.

Can this valve be used for dead-end steam service?
For dead-end or liquid service applications where tight shut-off is required, the 152AT model with a PTFE disc is typically recommended over the standard 152A.
