Pneumatic actuator controls

With traditional tubed pneumatic control circuits Bifold elements are said to be capable of the highest possible flow, but output is limited by the change in the bore size through the tubes and fittings.

Likewise with traditional nippled pneumatic control circuits Bifold elements are said to be capable of the highest possible flow, but the output is restricted by the diameter of the nipples.

Bifold has developed an unrestricted common bore system that optimises the high flow capability of its components. It has also developed patented Filter Boosters, removing as many elements as possible from the flow line including the filter and regulator, amplifying the possible flow for any given tube size. This principle results in smaller tube sizes being used and can be supplied in up to a 2in connection.
