Don’t Let Failing Valves Disrupt Your Operation

Valves are the silent workhorses of any industrial system—until they fail. A faulty valve can result in process inefficiencies, product loss, or even unplanned shutdowns. For industries like mining, chemical processing, water treatment, and manufacturing, valve reliability is non-negotiable.

At KV Controls, we specialise in industrial valve automation and supply, offering expert advice and premium products to resolve valve performance issues before they escalate.

Internal Wear and Tear

The Problem: High-cycle operations and abrasive flow media wear out internal valve components like seats, plugs, or stems.

The Fix: Regular maintenance and component replacement. KV Controls supplies robust valve designs and spares for high-wear environments.

For long-term reliability, we recommend options like segmented ball valves and globe valves with hardened trims or coatings.

Actuator Misalignment or Failure

The Problem: If the actuator doesn’t align or function properly, it can cause sticking, incomplete closure, or full failure.

The Fix: Actuator recalibration, or upgrading to advanced models. KV Controls recommends using electric or pneumatic actuators with integrated diagnostics to improve precision.

We also supply Schneider SRD998 valve positioners to enable smart automation and feedback loops.

Chemical Corrosion

The Problem: Aggressive chemicals can erode or corrode valve internals and body material over time.

The Fix: Material compatibility is key.

At KV Controls, we supply lined butterfly valves and stainless-steel body valves built for corrosive environments. We help clients select valves based on chemical composition, concentration, and temperature.

Pressure and Temperature Extremes

The Problem: Operating outside of design specs—especially in high-pressure or high-temperature systems—can deform or damage valves.

The Fix: Use valves with appropriate pressure and temperature ratings.

KV Controls stocks PN16, PN25, and PN40-rated valves, as well as temperature-resistant actuators suited for steam, oil, and gas applications.

Incorrect Valve Sizing or Selection

The Problem: Improper sizing leads to pressure drops, water hammer, noise, or cavitation.

The Fix: Trust KV Controls for proper valve sizing and selection. We calculate Cv, flow rates, and process variables to determine the right fit, reducing long-term risk and maintenance costs.
