    A simple in-line element called a pressure snubber is used to reduce the rate of flow of fluids into pressure instruments and controls. A small orifice in an adapter fitting dampens shock and fluctuating pressure effects by limiting the rate at which flow enters. The smaller the orifice, the greater is the dampening effect. The proper orifice size for any application depends upon the size of the pressurized chamber, the viscosity of the fluid and the required response time of the system.
    Orifice sizes from .004" diameter to .020" diameter are available. In general, large instrument chambers require large flow orifices. Viscous fluids require larger flow orifices than low viscosity fluids. Gases generally require small orifices.

    Pressure snubbers are used as in-line elements to reduce rapid pressure fluctuations in the following types of components:
  • Pressure Gages
  • Pressure Measuring Instruments
  • Air Piloted Valves
  • Hydraulic Piloted Valves


    • They can also be used to control the flow rate of fluid delivered to:
  • Air Cylinders
  • Hydraulic Cylinders
  • Fluid Actuators
