Ball Valves

A ball valve is one of the most effective shut-off valves available. They provide leak-proof service, can open and close quickly and allow flow in either direction, unlike a gate or globe valve. BM Engineering stock a wide range of ball valves, from ¼” to 6″ at our warehouse in Glasgow.

From general purpose two-piece ball valves, v-ball control valves and hygienic valves, to heavy duty ball valves for steam, we have a variety of sizes, end connections and materials to suit many applications.

We can also supply actuated ball valves on a next-day basis if you require automation for your process. Our actuated packages include: AtEx Ex-i and Ex-d, AS-i and 4-20mA control, which can all be assembled, tested and dispatched on the same day

Ball valves are an excellent choice for shutoff and control applications. They are durable, perform well after many cycles, are dependable and close securely even after long periods of disuse.

Ball valves are commonly a form of flow control, where a hollow or punctured ball pivots to open or close flow of a fluid or gases, therefore they are extremely versatile and can be used in thousands of industrial and commercial applications. Some example applications include:

  • Chlorine manufacturing or other gas processing applications
  • High pressure applications for air or water
  • Flowing systems on ships
  • Fire-safe lines for controlling water for fire suppression

Ball and gate valves essentially perform the same function. However, their physical qualities are significantly different. Ball valves have a stem and ball, which turns horizontally, and are commonly referred to as “rotational” valves. They are best suited to applications that require on/off control without pressure drop.

Gate valves open by lifting a round or rectangular gate out of the path of the liquid. The sealing surfaces between the gate and seats are straight, so gate valves are often used when a straight-line flow of fluid and minimum constraint is needed.
