Where ball valves are used

The construction and design of a ball valve make it suitable for a broad spectrum of services. With a simple quarter-turn operation, they can quickly open or close a pipeline, providing dependable isolation or flow control.

Typical applications include:

  • Water treatment plants and filtration systems
  • Steam, oil, and gas networks
  • Food and beverage processing
  • Chemical and petrochemical industries
  • Mining, marine, and HVAC systems
  • General manufacturing and plant services

Because of their straightforward design, ball valves are easy to maintain and deliver long service life. When correctly selected and installed, they resist corrosion, reduce leaks, and minimise unplanned repairs.

About our range of ball valves

Process Systems offers a complete range of ball valves to suit different operating conditions and industries. Our catalogue includes:

  • Stainless steel ball valves — Manufactured in 316 stainless steel, these are ideal for aggressive media and high-temperature or high-pressure applications. Options include 2-piece, 3-piece, and stainless steel flanged ball valves, all WaterMark approved. Many feature lockable handles for operator safety.
  • Brass ball valves – Cost-effective, compact, and versatile, brass models are constructed for general applications such as air, water, and non-aggressive fluids. Nickel-plated brass improves resistance to damage and corrosion.
  • PVC ball valves – Lightweight and chemically resistant, UPVC designs are suitable for irrigation, water systems, and corrosive chemical services. UV-stabilised construction protects against outdoor temperatures and sunlight.
  • High-pressure ball valves — Built with reinforced seats and precision-machined stainless steel balls, these units handle up to 200 BAR. They are ideal for hydraulic circuits and demanding applications requiring strength and safety.
  • High temperature ball valves – Fitted with PTFE + stainless steel seats to withstand up to 220°C, these are designed for steam and thermal oil systems where performance at elevated temperatures is critical.
  • 3-way ball valves – Available in L-port and T-port designs for diverting or mixing fluids. Offered in manual, pneumatic, or electric operated versions.
  • Actuated ball valves — Pneumatic spring return, double-acting, and electric actuators provide automated control, adding convenience and reducing manual handling. Capacitor return designs are ideal for anti-water hammer service.

Every ball valve is constructed with precision bore alignment, tested for leaks, and supplied with engineering documentation upon request.

How to choose the right ball valve

When choosing a ball valve, keep the following in mind:

  • Size and bore: Decide between full bore for unrestricted flow or reduced bore where cost or space is a factor.
  • Connection type: Options include BSP, NPT, flanged, and solvent weld. Confirm compatibility with your pipeline.
  • Materials: Stainless steel, brass, and PVC each have advantages depending on media, pressure, and temperature.
  • Seats and seals: PTFE is standard, while reinforced PTFE or Delrin provides extra strength for high-pressure or abrasive fluids.
  • Operation: Manual lever, gearbox, pneumatic actuator, or electric motor – choose based on automation and safety requirements.
  • Maintenance: 3-piece valves allow easier repairs and replacement of seats and stem seals, extending longevity.

FAQs about ball valves

  • What is a ball valve?

    A ball valve is a quarter-turn valve that uses a drilled ball to control flow. Turning the handle rotates the stainless steel ball or brass ball, aligning the hole with the pipeline when open, or blocking it when closed. Variations include 2-way, 3-way, floating ball, and trunnion-mounted designs.

  • How does a ball valve work?

    All ball valves operate by rotating the ball 90 degrees around its axis. This movement either allows fluids to pass through the bore or isolates the line. Depending on the construction, actuation can be manual, pneumatic, or electric.

  • How long will my ball valve last?

    Service life depends on applications, cycling frequency, and media. In clean services, longevity can exceed decades. In more demanding applications with corrosive fluids or abrasive conditions, more regular maintenance or repairs may be required. Lab testing shows 30,000+ cycles on Process Systems valves, depending on use case.

  • How do I install a ball valve?

    Most 2-way valves are bi-directional and easy to install. Simply connect the ends (threaded, flanged, or welded) to your pipeline. Always ensure the valve is correctly connected and tightened to avoid leaks or damage.

  • What are typical uses of a ball valve?

    Because of their versatility, ball valves are found across countless industries. Typical applications include water treatment, chemical handling, steam service, compressed air, gas, and general plant isolation. Their simple design and PTFE seats make them suitable for a wide variety of fluids.

  • How long will delivery take?

    If express freight is selected, orders usually arrive next day to metro areas for packages under 5 kg. Free freight orders go by road and generally take 1–10 days.

  • Is there a warranty provided?

    All Process Systems ball valves include a 12-month warranty. Each product is tested before shipping, reducing the risk of leaks or early failure. With proper use, they deliver long-term performance and longevity.
