Zetco Globe and Needle Valves

Globe and needle valves are commonly used in civil and industrial piping, with a wide range of gas and fluids, where the control of the flow (throttling) and a tight seal is required.

The shape of the closing mechanism (disc) is designed to reduce the turbulence in the flow, which makes them ideal for applications that require a flow control. When the disc is particularly small, the valve is called needle valve and is used for a more precise control of flow.

The operating mechanism ensures a progressive closure of the valve, which is particularly important when the flow of liquids must be blocked rapidly, without damage to the pipeline (water hammer effect). The globe valve design is responsible for a consistent pressure drop that needs to be considered during pipe design and installation.

Zetco Valves has an extensive range of globe and needle valves, in a variety of configurations, produced by ISO 9001 certified manufacturers. Copper alloys like brass and bronze are used for potable water applications where the antibacterial property of copper is beneficial. Stainless steel is commonly used where the application requires high pressure, high temperature and resistance to chemical aggression from the fluid or from the environment. Aluminium bronze is also available, upon request, for marine, mining and heavy industrial applications.

The range includes globe and needle valves with sizes from 6mm to 200mm, with screwed, bolted or union bonnet and with threaded or flanged connections. Threaded connections include the international ISO 7/1 standard (BSP) and the American ANSI/ASME B1.20.1 (NPT). Flanged connections include the Australian AS 2129 Table D/E/F/H, the American ANSI/ASME B16.5 in class 150 or 300 and the European EN 1092-1 PN16 (DIN).

Zetco Valves can offer a wide range of globe valves with Watermark certifications.
