This British industrial company has established a leading market share in valve actuators – devices fitted to valves to control the flow of fluid and gas. Rotork grew through the 2009 downturn when most industrial companies were seeing significant pressure in their business.

There’s nothing flashy about the valve actuator business, but Rotork has established itself as a force with strong product development based on understanding its customers’ needs.

Rotok is close to value, but the recent drop makes them attractive again at about £25 or less.
