  • Sliding gate valve with orifice-encircling spring
    Patent number: 4358034
    Abstract: Apparatus for applying a clamping force to slide gate valve plates to prevent leakage of molten metal therebetween. The apparatus applies the force uniformly about the annulus of the orifice of the plates and at a location close to the orifice itself, thus providing more effective clamping of the parts together. The apparatus may be either an annular mechanical spring mounted about the orifice of the plates or an annular chamber filled with gas under pressure.
