Watts 0830928 Regulator

The Watts 0830928 (Model 152A) is a 3/4-inch steam pressure regulator engineered for high-sensitivity response in demanding process applications. Designed specifically for steam, air, and non-corrosive liquids, this iron body pressure reducing valve manages initial supply pressures up to 200 psi. It provides a reliable reduced pressure range of 30 to 140 psi, ensuring full volume throughput with minimal pressure drop. This regulator is a standard choice for HVAC contractors servicing autoclaves, steam tables, sterilizers, and large-capacity process lines. The assembly features NPT threaded female connections, a stainless steel disc, and a laminated metal diaphragm for enhanced durability. A key technical advantage is the integrated sensitivity adjuster, which allows technicians to eliminate vibration and chatter under critical flow conditions. The Watts 152A-3/4-141 is fully serviceable in-line, reducing downtime during maintenance cycles.

• Precise Pressure Control: Highly sensitive to downstream changes, maintaining stable output even during fluctuations in supply.
• Durable Construction: Features a rugged iron body and stainless steel internal trim to resist erosion in steam service.
• Field Adjustable: The manual adjustment spring and sensitivity screw allow for fine-tuning to specific equipment requirements.
• Versatile Application: Ideal for process steam regulation in commercial kitchens, medical facilities, and industrial testing fixtures.
• Inline Serviceability: Designed for easy access to internal components without removing the valve body from the piping system.

What is the maximum inlet pressure for the Watts 0830928?
This regulator is rated for a maximum initial supply pressure of 200 psi at temperatures up to 400°F.

Can this regulator be used for "dead-end" service?
The standard 152A is a continuous flow regulator; for dead-end or liquid services requiring bubble-tight shutoff, technicians should verify if the "T" model (152A-T) is required for the specific application.

How do I stop the valve from vibrating or humming?
Use the built-in sensitivity adjuster to dampen the diaphragm's response to critical flow velocities, which eliminates common harmonic vibrations in the steam line.
