      Features: Plug in type Solenoid Valve for easier to replace the weak coils. All spools and bodies are interchangeable by retaining the same tolerance of internal leakage. The wet type of Solenoid valve, which is movable parts are immersed in the oil. It brings the feature of low noise. High voltage test up to 1500v/min. Insulation resistance test exceeds 100MΩ The momentary signal shifting takes approx. 0.1 sec. Spool shifting approx. 30,000,000 times H class insulation coils which can resisted up to 180°C   Packaging & Shipping How are orders packed and shipped?     Depends on customers' orders.
