Handling abrasive or chemically aggressive fluids is a challenge faced by many engineers in sectors such as mining, water treatment, and chemical processing. Valves used in these systems must perform consistently while resisting erosion, wear, and chemical degradation.
KDV Flow’s butyl-lined diaphragm valves provide an effective, non-metallic solution for controlling flow in harsh environments. Designed to reduce pump wear and maintain safe, uninterrupted operation, these valves have become a trusted choice in installations where durability and resistance are paramount.
Why Butyl Material Matters
Butyl rubber is widely recognised for its chemical resistance, flexibility, and resistance to abrasion. It is ideal for handling slurries, sediment-heavy flows, and aggressive low-pH media. In contrast to metallic valves that are prone to corrosion, butyl linings form a resilient barrier between the process fluid and the valve’s metal body.
KDV’s range of butyl-lined diaphragm valves is particularly suitable for plants dealing with gritty or scale-prone materials. Their robust sealing performance and wear resistance help ensure uninterrupted flow and longer service intervals.
Application in the Field
In a recent installation, KDV delivered a DN80 butyl-lined diaphragm valve paired with a C Series actuator for a high-solids processing application. The combination of abrasion resistance and automated control ensured precise shut-off and minimal downtime.
Similarly, DN300 units have been deployed in European operations managing bulk corrosive media. These larger valves provide high-flow capacity while maintaining exceptional sealing performance in demanding environments.
Valve Design that Protects Pumps
Pumps are often the first components to suffer when abrasive media is present in the flow system. Poor valve selection can lead to premature wear on seals, impellers, and other internal parts.
KDV’s weir-type diaphragm valves provide controlled, laminar flow that minimises turbulence and backflow. By isolating the media and reducing internal friction, these valves help extend the operational lifespan of pumps and reduce maintenance frequency.
Their compatibility with pneumatic and electric actuators also supports seamless integration into automated systems—ideal for process environments where precision and responsiveness are key.
Low Maintenance, High Value
Engineered with long-lasting butyl diaphragms and simple construction, KDV’s diaphragm valves require minimal maintenance. When service is required, diaphragm replacement is straightforward, and modular designs allow for quick actuator swaps or upgrades.
This results in reduced total cost of ownership and improved asset availability—an important consideration for plant managers operating under tight schedules and budgets.
Built for Industry, Backed by Experience
From dewatering in mining operations to handling acidic by-products in chemical plants, butyl-lined diaphragm valves have earned their place in applications that demand both chemical resilience and mechanical toughness.
With support from KDV’s global network—including stock and technical teams in Australia, the UK, and Southeast Asia—engineers can access dependable valve solutions with confidence.
