1).Smart shape, Perform reliably, large output torque, as long as 50000-100000 times. multi-angel assembling, convenience for all kinds of requirements. 2).Float ball design, no leak, most suitable for heavy dirt and long time no action. 3).The conditions that solenoid valve can not be worked. 4). Under the pressure between 1Mpa and 2Mpa, the working current is only 45mA to 100mA (it depend on the different type) 5). High protection class, can be worked in moist conditions.
