Fixed- Cone Control Valve

Installation Location:

●Installed in transmission/distribution pipelines or bypass lines.

Main Applications (by Control Function):

●Pressure sustaining / pressure relief control: Stabilizes upstream (inlet) pressure.

●Pressure reducing control: Stabilizes downstream (outlet) pressure

●Flow control: Maintains a constant flow rate.

●Combined pressure sustaining & pressure reducing control: Simultaneously controls both inlet
    and outlet pressures.

Product Features:

●Axial-flow passage design with stable annular flow distribution.

●Fixed cone and guide vane structure to enhance flow guidance efficiency.

●Movable sleeve regulates the orifice opening to adjust flow rate.

●Energy dissipation tube and guide vanes effectively reduce vibration, noise, and valve body erosion.

●Extremely low head loss at full open position, making it suitable as a pipeline terminal discharge
   valve or flow control valve.

Operating Principle:
●The valve guides the fluid through a fixed cone and guide vanes to form annular flow. Flow regulation
    is achieved by a movable sleeve supported by guide rails to adjust the orifice opening.

●Specially designed energy dissipation tubes and guide vanes eliminate vibration and noise, while
    preventing erosion from directly impacting the inner surface of the valve body.

Design Characteristics:
●Floating seat design with metal-to-metal seating: Standardized design eliminates
   concerns of rubberaging or damage, extending service life.

●Fixed cone design: Special annular flow passage reduces cavitation.

●Energy dissipation tube design: Effectively reduces vibration and cavitation effects
   acting on the valve body.
