Watson McDaniel B Series 1/2″ Pressure Regulating Valve

The Watson McDaniel B Series 1/2″ Pressure Regulating Valve is a high-quality valve designed to control and maintain the pressure of fluids in industrial systems. The valve is typically used for regulating steam, water, or other fluids to ensure stable operating pressures in downstream equipment or processes.

Key Features:

1. Pressure Regulation:

   • The B Series is a pressure-reducing valve that automatically maintains a constant downstream pressure by adjusting the flow of fluid based on the system’s pressure requirements.
   • It is ideal for use where precise control over fluid or steam pressure is necessary to protect equipment and maintain system performance.

2. Size:

   • The 1/2″ size refers to the valve’s connection size, suitable for 1/2-inch pipe in systems with relatively low to moderate flow rates.

3. Materials:

   • The valve body is typically made from cast brass or stainless steel, offering good durability and corrosion resistance, particularly for steam or water systems.
   • Internal components, such as springs and diaphragms, are typically made from stainless steel or other durable materials designed to withstand high pressures.

4. Pressure Range:

   • The Watson McDaniel B Series valve is designed to control downstream pressure within a specific range, typically between 5 to 250 PSI for steam and similar fluids.
   • The exact operating range will depend on the specific model, so it’s important to check the datasheet for your application.

5. Set Pressure Adjustment:

   • The pressure-regulating valve features an adjustable spring mechanism that allows users to set the desired downstream pressure.
   • It can be adjusted by turning the adjustment screw to increase or decrease the spring tension, altering the downstream pressure.

6. Temperature Range:

   • This valve can generally handle temperatures from -20°F to 400°F (-29°C to 204°C), which is common for pressure-regulating valves in steam or water systems.
