Pneumatics components

• Automatic drain

  Allows water to escape when a set level is reached
• Conditioning unit

  Contains filter, pressure regulator and lubricator

  In one unit
• Conditioning unit

  Combined filter , moisture separator , pressure control valve and pressure gauge
• Sequence valve

  Used to operate actuators and valves in a circuit in a particular sequence dependent on pressure
• Variable pressure relief valve

  Allows fluid to vent/escape if pressure is excessive
• Pressure regulator

  Controls pressure in the System
• Dual direction hydraulic motor

  Converts hydraulic pressure into rotary motion . Reversible
• Variable dual direction hydraulic motor

  Converts hydraulic pressure into rotary motion. . Reversible
• Dual direction pneumatic actuator

  Converts pneumatic pressure into rotary motion
• Single acting cylinder

  Converts fluid pressure into linear mechanical movement (Spring action on return)
• Double acting cylinder

  Fluid pressure will act on forward and return stroke
• 2 port/2 position. Directional control valve   (2/2 DCV)


  To open and close flow
• 3 port / 2 position directional control valve (3/2 DCV)

  Various uses
• 4 port 2 position directional control valve (4/2 DCV)


  Directs fluid to and from components
• 5/2 DCV

  Can be used as either 3/2 or 4/2 DCV
• 4/3 DCV

  Directs air/oil to the cylinder (allows cylinder to be locked)
• Operating line

  Line for transmission of fluid to allow useful work
• Pilot line

  Line for transmission of fluid to allow activation of DCVs etc
• Check valve / non-return valve

  Allows flow in one direction only
• Variable choke

  Varies the restriction of flow
• Variable one way flow control valve

  Controls flow in one direction only
• Shuttle valve (OR element)

  Allows one output from either of two inputs
• Shuttle valve (AND element)

  Allows one output from both inputs together
• Air dryer

  Removes moisture from air by passing it through moisture absorbent crystals
• Actuator / receiver

  Stores hydraulic pressure/

  Stores Pneumatic Pressure
• cooler


  cools fluid
• Tank

  Allows hydraulic fluid to escape from system
• Filter

  Cleans fluid of contaminants
• Lubricator

  Allows oil into air flow
• Drain

  Allows water to escape from compressed air circuits
