There are four types of steam control valves available for use on a steam fired storage water heater.

Self Operating

The valve design includes a bulb and capillary assembly charged with a thermally responsive vapor. The expansion/contraction of the vapor acts upon the valve bellows in order to control the flow of steam through the valve. No external power source is required for

operation.

Pneumatically Operated

In this configuration the ships air supply feeds a factory installed temperature controller which operates the steam control valve. The temperature controller sends a precise air signal to the steam control valve which adjusts the flow of steam into the heating coil. The temperature controller is fully adjustable from 50-250°F and requires 20psi air at a maximum consumption of 0.5

SCFM.

Pilot Operated

A pilot operated control valve is the most widely used type of valve for standard water heating applications. In this type of valve, a temperature pilot device utilizes steam to operate the main valve. No external power source is required other than steam. This is a highly dependable temperature control system which is suitable for most applications. As an option, this valve may include a pressure reducing pilot which limits the steam

pressure to a predetermined maximum.

Electronic Operated

This control valve is similar to a pneumatically operated system, except in this case the temperature controller is a sophisticated digital display electronic device which outputs a 4-20ma signal to a compact motor mounted on the steam control valve in order to proportionally control the flow of steam to the heating coil. The temperature controller displays set point as well as actual water temperature and is available with an RS485 communications port for remote control.

This series can provide an impressive lumen output, making it suitable for warehouses, parking lots, and stadiums. The fixtures typically come with various wattage options, allowing users to select the output that best fits their specific needs.

On the other hand, the MSH series utilizes high-intensity discharge (HID) technology, known for its energy efficiency and long lamp life. These fixtures are designed to withstand harsh environmental conditions, making them ideal for outdoor applications such as street lighting and security lighting. The robust construction of MSH fixtures ensures that they can endure exposure to moisture, dust, and varying temperatures.

Among the key characteristics of both series is their compatibility with a range of control systems. Hubbell MH and MSH fixtures can be equipped with optional dimming and photo sensors, enabling smarter, more energy-efficient lighting management. This feature not only reduces energy consumption but also extends the lifespan of the lamps, resulting in lower maintenance costs.

Both series are designed with user-friendliness in mind, featuring tool-less entry for easy access to electrical components for maintenance or replacement. In addition, the fixtures offer adjustable mounting options, allowing for flexible installation in different environments.

The advanced reflector design in these fixtures ensures superior light distribution, minimizing dark spots and enhancing overall visibility. This focus on light quality is crucial for creating safe and productive environments in various settings.

Hubbell's ongoing commitment to sustainability is reflected in the design of the MH and MSH fixtures, as they prioritize energy efficiency and low environmental impact. By investing in these lighting solutions, users not only benefit from enhanced visibility and safety but also contribute to a greener future. In conclusion, the Hubbell MH and MSH series exemplify innovation in lighting technology, characterized by their efficiency, durability, and adaptability to diverse applications.
