SKP75 Air/Gas Ratio Controlling Gas Valve Actuator (120V)

SKP75 pressure regulating electro-hydraulic actuators are used in combination with VG series gas valves to provide slow opening, fast closing safety shut-off and air/gas ratio control for industrial and commercial burner applications.

The SKP75 controls the burner manifold gas pressure as a function of the combustion air pressure without the need for an additional constant gas pressure regulator.

Since three functions: safety shut-off, constant pressure regulation, and air/gas ratio control can be performed by a single valve, fewer gas train components and fittings are required. This significantly reduces both the size and weight of the gas train. In addition, smaller diameter gas valves can be used.

The compact SKP75 actuator opens slowly and closes immediately when power is interrupted. The modular design allows the SKP75 to be used in combination with all VG series gas valves bodies from 1/2-inch to 6-inch in size. The actuator is easily mounted on the square flange of any VG valve with four pre-mounted screws. A visible position indicator on the front of the actuator displays the entire stroke of the valve. A light indicates when the actuator is powered.

Features:

• Excellent control for recuperative burners, burners utilizing preheated combustion air, and variable orifice/flow regulating burners
• Air/gas ratio maintained even when air flow is disrupted
• Safety shut-off control and pressure regulation in one compact unit
• Compensates for variations in combustion chamber back pressure
• Low-fire, excess-air biasing adjustment
• Simplified commissioning of burner and reduced start-up time
• Optimal solution for premix burner applications
