Pressure Controllers Manufacturers

Pressure controllers consist of two chambers separated by a diaphragm, with a needle valve in the center actuated by the diaphragm. The diaphragm is held down by a spring that is adjustable. If the pressure falls in the upper cylinder, the diaphragm moves upward due to the pressure in the lower chamber. These are fine-tuned at the outer end of the cylinder and gain the rod side at the opposite end of the cylinder. This is associated with gas chromatograph. The reducing valves on the gas tanks are examples of simple pressure controllers. They are used for seat checking and to verify the pressure.
