Built For The Harshest Applications: Corflex Engineering Marks 45 Years Of Pinch Valve Expertise
For 45 years, Corflex Engineering (Pty) Ltd has built its reputation on a simple principle: industrial equipment operating in demanding environments must be designed to withstand the conditions it faces. Established in 1981, the company has become a trusted supplier of specialised industrial pinch valves to the mining and allied industries, where abrasive materials and high-density slurries place significant demands on process equipment.
Mining operations rely on the continuous movement of dense, abrasive slurries, making valve performance critical to maintaining production efficiency. In these applications, conventional valve solutions can be exposed to significant wear, potentially resulting in maintenance requirements and unplanned operational downtime. Corflex pinch valves are engineered specifically for these harsh conditions, providing a robust solution for controlling abrasive slurry flows. The company supplies both high- and low-pressure pinch valves, with configurations selected according to the requirements of each application. Open-frame pinch valves are available for low-pressure duties, while enclosed-body designs are manufactured for high-pressure applications. This allows Corflex to provide solutions across a broad range of demanding industrial processes.
At the heart of the Corflex pinch valve is its reinforced rubber sleeve. These sleeves are hand-built and manufactured with a 3:1 safety factor, reflecting the company’s focus on durability and dependable performance. The sleeve forms the primary wear component of the valve and is designed to handle the abrasive nature of slurry applications while helping to protect the valve body and associated equipment. Corflex’s manufacturing capabilities continue to support specialised requirements for clients across the region and beyond. A current example is the manufacture of 500 mm pinch valves rated for a working pressure of 25 bar for a repeat client in Zambia. The project demonstrates not only the company’s ability to manufacture large, high-pressure equipment, but also the confidence returning customers place in its products and technical expertise.
For mining and mineral processing operations, reliability is about more than keeping equipment running. Every unplanned stoppage can have an impact on production schedules, maintenance resources and overall operating costs. Equipment designed specifically for the conditions in which it will operate therefore plays an important role in supporting plant availability.
With four and a half decades of experience, Corflex Engineering has developed a deep understanding of the challenges associated with abrasive slurry handling. Its focus on specialised pinch valve technology, robust reinforced rubber sleeves and application-specific solutions has enabled the company to remain relevant in an industry where equipment durability is essential.
As mining operations continue to demand greater efficiency, reliability and reduced downtime, the importance of dependable flow-control equipment will only increase. Corflex Engineering’s 45-year track record demonstrates the value of combining established manufacturing expertise with products designed specifically for some of the most challenging industrial applications.
From low-pressure open-frame designs to high-pressure enclosed-body valves, Corflex continues to provide the mining and allied industries with solutions engineered to handle the pressure, abrasion and demanding conditions of modern slurry applications.
