  • Differences between Direct – acting Solenoid Valve and Distributed Direct – Acting Solenoid Valve

    Straight acting solenoid valve: Principle: power, the electromagnetic coil to produce electromagnetic force to close the closure from the valve seat, the valve open; power, the electromagnetic force disappears, the spring to close the valve on the valve seat, the valve closed. Features: in the va...

  • What is the ball valve

    The ball valve only needs to rotate with 90 degrees of operation and the small rotational moment of force can close tightly. The fully equal bore of the valve body provides a very small, straight-through flow path for the medium. Ball valves are generally considered to be most suitable for direct...
