    Ancillary Equipment Vacuum Breakers CVU15

    Features/Applications

    Features

    • Superb durability

      The body of the product is made from stainless steel, making it durable and corrosion-resistant.

    • Compact and cost effective design

      It has a space saving, simple mechanism with very few moving components.
      It is only vertical installation.

    • Wide range of use pressure and temperature

      Max. operating pressure is 2,1MPa (305psig) and max. operating temperature is 450℃ (842°F).

    The CVU15 vacuum breaker is an automatic valve that takes in air from outside into a steam system and  breaks occurred vacuums.

     

    Typical applications

    Suitable for steam devices, steam lines, and liquid devices such as boiler tanks.

    ●Maximum allowable pressure (PMA): 2,1MPa (305psig)PMA is the pressure that can be tolerated by pressure-resistant parts (body) .
    ●Maximum allowable temperature (TMA): 450℃ (842℉)TMA is the temperature that can be tolerated by pressure-resistant parts (body).
    ●Differential pressure of at least 0,5kPa (0.07psig) is required to open the valve.

    Operating Principles

    ■ Normal state
    In a normal state, pressure P1 inside the line is applied to the connection, and the pressure P2 of the air intake is atmospheric pressure.
    P1 is higher than P2 (P1>P2), and the valve is closed by this differential pressure.

    CVU15-1.png

    ■Operating state
    If the pressure in the line becomes negative, the pressure P1 at the connection becomes lower than the pressure P2 at the air intake (P1<P2).
    The valve is opened by this differential pressure.
    The valve is closed when the air flows in the line and the pressure in the line is increased. It will return back to Nomal state.
