Besides, hydraulic solenoid should have ability to react to hygrothermal environment. Rubber seal of hydraulic solenoid requires aging resistance. Structural requirement of hydraulic solenoid Ageing Resistant & Humidity Resistance In general, residual magnetic force of hydraulic solenoid should be less than the 18% of rated force.Ĭharacteristics of hydraulic solenoid Hierachical voltage controlĪC 50Hz (V): 110, 220, 380. Residual magnetic force: when the power is off, the residual force from iron core called residual magnetic force. Retaining force: when the solenoid is powered, the effective force is created by iron core at the holding position, which is known as retain force. In the range of rated stroke, supply voltage is 85% of rated value, force of solenoid should be not less that the required rated force. Stroke: Stroke refers to the effective displacement that ensures the output force of solenoid from starting position to closed position.įorce: in terms of the stroke direction, after overcome the friction, solenoid output the effective force called the force. There are common terms for hydraulic solenoid, such as stroke, force, retaining force and related marks As for the working principle, dry-type solenoid is same as wet-type solenoid. Dry-type solenoid: it is one-stroke solenoid, and pressure oil is not allowed to flow into magnetic path or coil of solenoid.

When the solenoid is power off, the iron core get back to the original position. In the magnetic exciting status, solenoid coil control the iron core from on position to off position. Wet-type solenoid: it is one-stroke solenoid, and pressure oil is allowed to flow into guide sleeve of solenoid.Hydraulic Solenoid ClassificationĪccording to different ways, the hydraulic solenoid can be divided into many types, for example, By power: AC solenoid and DC solenoid By structure: wet-type solenoid and dry-type solenoid We sum the features of hydraulic solenoid up for the solenoid selection. Except for the application, how much do you know about features of hydraulic solenoid? As a hydraulic solenoid supplier, KaiDi has rich experience in processing on-off solenoid, proportional solenoid, explosion-proof solenoid and custom solenoid. Hydraulic solenoid has great applications like switch valve, proportional valve, and explosion-proof valve. The main function of hydraulic solenoid is control fluid or switch. Hydraulic solenoid for control valve is used as basic element of hydraulic valve.
