Junction Blocks

Junction blocks, also known as distribution blocks, are pneumatic system components that create junctions for the distribution of media throughout the system. Junction blocks are designed to distribute media—fluid or gas, depending on the system—from a single output source through two or more output ports. Pneumatic distribution blocks are manufactured with multiple outputs. The maximum number of outputs a junction block can support is dependent on the pressure load of the pneumatic system in which the block is installed. If the system lacks the power to consistently pump fluids or gases through all the distribution block’s outputs, the entire system will fail. The more output ports a junction block has, the greater the pressure the pneumatic system as a whole will require. Distribution blocks can be manufactured from a wide variety of common and specialty materials, including aluminum, stainless steel, brass, nylon, polypropylene, and others. The function and capacity of the pneumatic system generally dictates the material of construction of the junction block used. Input and output connection on pneumatic distribution blocks is usually as simple as screwing two threaded pipe ends together. For the most part, junction blocks are manufactured with NPT threading, though other standard thread types may be used. Specialty connections may be used, depending on the needs of the system.
