Steam valve

    This is a novel fluid-controlled make-up quick-closing valve for steam extractors. Actuators in hydraulic systems Hydraulic cylinders feature a special construction and are installed in unusual and practical side-by-side ways to close quickly and reduce the space required for installation.

    As the implementation of the hydraulic cylinder with bypass installation, in the event of fuel tank leakage, the leakage of oil will not fall on hot valves and steam lines, which can effectively prevent the occurrence of a fire accident. At the same time, the pressure of the hydraulic cylinder is low pressure, which is generally based on the regulating oil of the steam turbine as an oil source, thereby eliminating the need of adding a high-pressure hydraulic station and to a certain extent, reducing the cost for the user.

    Hydraulic cylinder control unit, can be set separately, can also be combined to the speed control device (quick closing assembly) on.
