Maxitrol Gas Combination Controls

Maxitrol Gas Combination Controls

Maxitrol Combination Controls from N.H. Yates!

Gas valves are used to regulate the flow of flammable gases to and from a boiler or other gas equipment. Redundant gas valves control the passage of gas to the burner in a gas furnace or other gas-fueled devices. The purpose of a redundant gas valve is to allow the pilot valve operator, or, the main valve operator to shut off the flow of gas to the main burner. This redundancy creates more options and allows opportunities to keep the gas from the burner whenever necessary. Maxitrol Combination Controls are perfect for use in many applications such as gas boilers, power burners, spa heaters, wall furnaces, gas fires, patio heaters, agricultural heaters, and commercial cooking appliances. In addition, these combination controls are suitable for natural, manufactured, mixed gases, liquefied petroleum gases, and LP gas-air mixtures. At N.H. Yates, we are proud representatives of the entire line of Maxitrol products, including the Maxitrol Combination Controls.

Models of Maxitrol Combination Controls

Maxitrol Combination Controls for gas equipment come in several models that are appropriate for different application and needs. Here is a brief outline of each model and their capabilities:

Maxitrol Combination Control Model CV100

Maxitrol Gas Combination Controls

The CV100 is a single solenoid shut-off valve with an integrated pressure regulator. This model gas regulator is used for applications with high capacity pilot lines such as gas boilers and power burners.

Maxitrol Combination Control Model CV200

Maxitrol Gas Combination Controls

The CV200 is a dual-solenoid shut-off valve with an integrated pressure regulator. The CV200 is a redundant combination control that is used in direct spark or hot surface ignition applications. This unit eliminates the need for a standing or continuous burning pilot flame. Some appropriate applications for the CV200 include direct vent gas-fired baseboard heaters, space heaters, wall furnaces, water heaters, gas fireplaces, and commercial cooking appliances.

Maxitrol Combination Control Model CV300

Maxitrol Gas Combination Controls

 

The CV300 is a dual solenoid shut-off valve with an integrated pressure regulator, however, an optional pressure regulated pilot gas outlet is available. Appropriate applications for the CV300 include gas fires, commercial cooking appliances, and patio heaters.

Maxitrol EXA Star Modulating Valves

EXA Star Modulating Valves

Maxitrol EXA Star Modulating Valves

Modulating control valves change the flow of fluids, pressure, level, and temperature control of a system. Most modulative values are made up of three main parts: a valve body, an actuator, and a positioner. The positioner, through the actuator, drives the valve based the setting of the control signal. The Maxitrol EXA Star Modulating Valves are equipt with a built-in digital controller that gives a seamless interface with a process controller. The valve has two buttons and a communication LED for the user interface which is used to set the valve for high and low fire settings. In addition, the valve has full open and full close mechanical limits. This feature adds dimension for sizing and applying is significant because it allows the valve to be set up for an entirely different net output depending on pressure supply. The EXA Star Modulating Valve has six electronic connections – two for the power, two for the control signal, and two for the position feedback.

Linear Maxitrol EXA Star Modulating Valves

EXA Star Modulating Valves

Maxitrol’s E42, E52, and E62 Series EXA Star Modulating Valves are designed to have a linear relationship between the control signal and flow rate. This flow rate linearization will optimize over a 5:1 turndown ratio with the maximum flow rate determined at 1″ w.c. pressure drop. With applications in areas with atmospheric low-pressure, these modulating valves consistent gain allows the controller’s entire signal range to be utilized and tuning is simplified. This is a significant improvement over traditional designs. Rather than using a ball, butterfly, and poppet valve, the EXA Star modulating valve has a built-in digital controller that provides a seamless interface with the process controller. This allows the installer to set the high fire and low fire settings and establish mechanical limits for the valve.
