1.Excellent oil immersed type electromagnetic action design. The slide dip in the oil system has buffer action, still smooth and silent even under high pressure high frequency switching action. It completely eliminates the friction between the oil seal and the sliding push rod and the oil leakage problem caused by the oil seal, and can increase the thrust of the sliding column.
2.Reduce the temperature to improve life, save maintenance cost. Due to the flow passage of the hydraulic shuttle valve body uses a special structural design, and low internal resistance, using pressure drop reduced, temperature of hydraulic oil can also be reduced accordingly, making the hydraulic oil not easy to deteriorate, prolonging the service life of hydraulic oil and reduce hydraulic oil replacement costs.
