Watts 0830920 Reg

The Watts 0830920 (Model 152A-3/4-146) is a professional-grade steam pressure regulator designed for high-sensitivity applications where precise downstream control is non-negotiable. Featuring a rugged iron body and 3/4 inch FNPT connections, this direct-acting valve is a standard for contractors servicing autoclaves, steam tables, sterilizers, and vulcanizers. It effectively replaces legacy models 152A-3/4-146 and 152A-M3-3/4-10-50, ensuring seamless integration into existing process lines. With an adjustable pressure range of 10 to 50 psi and a maximum inlet rating of 200 psi, this unit maintains full flow capacity with minimal pressure drop across the seat.

Engineered for technical reliability, the Watts 152A series utilizes a stainless steel disc and stem guide to resist the corrosive effects of high-temperature steam and non-potable liquids up to 300°F. The 152A-3/4-146 is built for in-line serviceability, allowing for maintenance without removing the valve body from the piping. For technicians troubleshooting critical flow vibrations, the integrated sensitivity adjuster provides fine-tuned stability, making it the preferred Watts process steam regulator for institutional and industrial steam systems.

• Versatile Application: Ideal for autoclave pressure regulation, steam irons, and single radiator heating systems.
• Internal Durability: Equipped with a stainless steel strainer screen and seat to protect internal components from scale and debris.
• Precision Control: High sensitivity to reduced pressure changes ensures stable operation even during fluctuating demand.
• Direct Replacement: Explicitly designed to replace 152A-M3-3/4-10-50 and older 152A series variants without repiping.
