Brandoni 14.000 – Needle Control Valve

The Brandoni 14.000 is a needle-type control valve designed for regulating water flow in pipelines. Flow adjustment is achieved via axial movement of a piston, operated by a shaft and handwheel mechanism. Regulation is performed by closing against the flow direction, within a pressure-balanced chamber.

Technical Specifications

  • Connection: Flanged

Control Characteristics

At openings below approximately 40%, significant pressure losses occur. Above 50% open, pressure losses decrease substantially. Selection of operating position should be based on flow rate, available Δp, and cavitation risk.

Anti-Cavitation Arrangement

For high differential pressures, a perforated stainless steel cylinder can be installed. K20, K50, K100, and K150 variants modify pressure loss and cavitation resistance characteristics.

Applications

  • Water treatment and distribution systems
  • Atmospheric discharge with high Δp
  • Flow control in main pipelines
  • Network protection from hydraulic transients
  • Isolation function where specified by design

FAQ

When is it preferred over a butterfly valve?
When controlled energy dissipation is required, not just isolation.

What should be checked before selection?
DN, flow rate, upstream/downstream pressure, discharge scenario, cavitation index, and actuator type.

Description

NEEDLE VALVE

The needle valve is mainly designed for water flow regulation in a pipeline.

The flow regulation is achieved by the axial movement of a piston, which is operated by a rod and crank mechanism.

The piston reduces the flow by closing in the flow direction, and operates in a housing with equalized pressure; this allows the valve to operate in a stable and smooth manner, without vibrations and with a low operating torque.

The regulation is achieved with high head losses, when the valve is less than 40% open, and very low head losses, when the valve is more than 50% open.

YES: for shut-off operation and for discharge to the atmosphere with high pressure differentials.

The valves are suitable for all kinds of water plants.

Available for pressures up to 64 bar.

All sizes (DN) are supplied with a gearbox.

If necessary (because of the operating conditions), the shutter can be equipped with a stainless steel slotted cylinder (anti cavitation device), which allows modulation of the energy dissipation, thereby achieving greater resistance to cavitation, and modification of the regulating curve of the valve to meet the requirements of the plant.

Accessories

  • Anti-cavitation device
  • Standard slotted cylinder (K20, K50, K100, K150) are available with increasing anti-cavitation resistance characteristics and head losses.
  • Actuators Gear box (standard)
  • Electric actuators
