SKP25 pressure regulating electro-hydraulic actuators are used in combination with VG series gas valve bodies to provide safety shut-off and gas pressure regulation for industrial and commercial burners. The SKP25 can also be applied as a 1:1 air/gas ratio regulator or zero governor. Since a single valve performs two or more functions, 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 SKP25 actuator opens slowly and closes immediately when power is interrupted. The modular design allows the SKP25 to be used in combination with all VG series gas valve 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.
