Abstract
A pressure regulator valve arrangement comprises first (14) and second (24) regulator valves for closing a fluid passage (4) in the event of over-pressure. The valve members each have pressure ports for sensing the pressure, the ports being located downstream of the valve members to minimise interaction between the valves.
