Main Products
FOX SOLID CONVEYING EDUCTORS
Since 1963, Fox Valve has been a leading global supplier of Venturi Eductors and transport systems for dilute-phase pneumatic conveying of powders, pellets, and bulk solids. Also known as jet pumps, Fox Eductors use low-pressure air to efficiently move dry bulk materials through pipelines without moving parts. Their simple, robust design provides reliable conveying performance with minimal maintenance, making them suitable for a wide range of industrial applications.
FOX AIR AND GAS JET EJECTORS FOR PUMPING GAS OR CREATING VACUUM
Fox Air and Gas Jet Ejectors are specialised devices designed to pump gases or create a vacuum using the Venturi effect. Operating without moving parts, they use a high-velocity jet of air, steam, or gas as the motive fluid to entrain and compress the suction gas. Their simple and robust design provides reliable, low-maintenance performance for various industrial gas handling and vacuum applications.
FOX LIQUID EDUCTORS
Fox Liquid Eductors are Venturi jet pumps that use a liquid motive flow to create vacuum and efficiently mix, blend, or dilute liquids, dry solids, and gases into a liquid stream. With no moving parts, they provide simple and highly reliable operation. Fox Liquid Eductors can also replace or eliminate conventional pumps in applications requiring dependable and efficient liquid mixing.
Industry Application

CEMENT INDUSTRY
Fox Eductors provide reliable pneumatic conveying solutions for cement plants, handling materials such as cement kiln dust (CKD), cement, limestone, and other abrasive materials. Applications include conveying beneath dust collectors, injecting waste and alternative fuels into kilns, sorbent injection and mercury capture, and conveying hot kiln spills at temperatures up to 1,500°F. With no moving parts, Fox Eductors offer a robust, low-maintenance solution for demanding cement applications.
FOOD INDUSTRY
Fox Venturi Eductors provide reliable pneumatic conveying solutions for food processing applications, including the transfer of pet food, kibble, kitty litter, and other dry bulk products. With no moving parts, these systems offer low-maintenance and dust-controlled conveying. A common application is in packing areas, where a Fox blower and eductor system can be installed directly within the packing room for efficient and hygienic material transfer.

PLASTICS INDUSTRY
Fox Eductors have been used since 1963 for the reliable pneumatic conveying of plastic pellets without moving parts. With decades of experience serving plastics compounders, Fox offers eductors specifically designed for compounding applications. Features include easy-to-clean internals, customised product inlet ports for seamless equipment integration, and optional ceramic liners for conveying abrasive or filled pellets, providing durable and efficient material transfer.
Components and Functionalities

FOX EJECTORS FOR METHANE CAPTURE
Fox Ejectors provide a reliable solution for methane capture and recovery in oil and gas applications. Methane, the primary component of natural gas, is a significant greenhouse gas and can be released through leaks and fugitive emissions from wells, gas processing plants, and onshore and offshore facilities. Fox Ejectors can help capture and transfer methane without moving parts, supporting safer operations and improved emissions control.
FOX MINI-EDUCATORS
Fox Mini-Eductors are compact Venturi eductors that use pressurised gases or liquids to generate suction for sampling, pumping, mixing, and vacuum-generation applications. Available in a wide range of materials, including 316 stainless steel, Teflon, CPVC, Monel, Hastelloy, and brass, they offer versatile solutions for different operating conditions. Fox stocks a broad selection of standard Mini-Eductors for quick availability and delivery.
VENTURI FLOWMETER
Fox Venturi Flowmeters provide accurate and reliable flow measurement using differential pressure across the Venturi tube. Designed for flexible installation, they are available with various connection options, including NPT, BSP, AN, and SAE. Fox can also provide customized welded tube or pipe fittings to suit specific process requirements, making these flowmeters ideal for aerospace and other industrial applications.
