Vortex Valve Cage Insert Design and Technical Advantages
The insert for a ball and seat valve comprises a tubular cylindrical body formed by vertically spaced apart top and bottom rings joined by helically inclined and circumferentially spaced apart ribs defining side openings.
The ribs support inwardly arching ball guide flanges which thin in cross-section as they extend inwardly and upwardly from the ribs. The inner upper ends of the flanges are connected with and tied together by an elongate, upwardly extending reinforcing member protruding above the top ring. The reinforcement member provides structural strength to the thinned flanges.
Thinning of the flanges leads to increasing the open area of the top outlets, thereby promoting the volumetric fluid capacity of the valve.
One-Piece Helical Cage Design and Technical Advantages
GAS BREAKOUT - The insert creates a spherical flow profile to keep the ball from rattling around allowing the gas to stay entrained in solution across the smallest cross sectional area in the pump.
PRESSURE DROP - The insert provides a 38 to 42 % decrease in pressure drop by pinning the ball with the spherical flow profile agains the spherical ball stop to keep the ball from rattling around and creating pressure drop across the smallest cross sectional area in the pump.
