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.
