Electrohydraulic actuators featuring delayed opening and rapid closing.
The electrohydraulic SKP10... actuators open slowly and close rapidly. All types of VG... gas valves can be combined with the available types of actuators. The actuator is fitted to the valve body by means of the 4 screws contained in the terminal compartment. The square flange can be turned in steps of 90°, thus providing 4 different mounting positions. The actuator can be fitted or replaced while the valve is under pressure. Sealing materials are not required.
The actuator’s hydraulic drive system consists of a cylinder filled with oil and an electric oscillating pump with piston and relief valve. The relief valve is located in the bypass between the suction and pressure side of the pump. With the actuators of the B-series, it is a valve hydraulically actuated by the pump pressure; with the 2-stage actuators of the A-series, it is a normally open solenoid valve. The cylinder carries a seal which hydraulically separates the inlet from the outlet side of the pump, also serving as a guidance for the piston. The piston is also guided by a rod which is rigidly connected to it. This rod transfers the piston’s travel directly to the valve stem. The rod is provided with a disk the position of which is visible through a window in the console (indication of stroke).
Using a lever system, the disk also actuates
the auxiliary switch for indicating the fully closed position, or
other positions, as well as the limit changeover switches for positioning the lowand high-fire stroke with the two-stage actuators.
The switching points of these switches are adjustable over the entire stroke. The adjusting screws are located in the terminal compartment. |
