ACT Ball Valves: KHB and KHM Models

ACT Ball Valves: KHB and KHM Models

ACT ball valves (KHB and KHM models) are high-precision components designed for shutting off and opening flow in demanding hydraulic systems.

When your application requires extreme robustness and flawless sealing, the steel models with internal threads according to the DIN ISO 228 standard are the ideal technical choice.

Why choose the DIN ISO 228 Steel Series?

This line is recognized for its versatility and resistance, being compatible with most standard market Whitworth internal thread connections.

  • Pressure Capacity: Designed to operate safely at nominal pressures of up to 500 bar (depending on the chosen size).
  • Robust Construction: The body and connection parts are made of high-quality steel, ensuring superior mechanical durability.
  • Specialized Sealing: Equipped with POM (polyoxymethylene) sealing shells and NBR (Perbunan) shaft seals, ensuring complete leak-tightness.
  • Mounting Flexibility: Can be installed in any position, adapting perfectly to your equipment’s layout.
