• Corrosion Protection: All the light aloy parts are hard coated.  The steel parts are
  galvanized.  The major parts which have the most stress are produced out of steel.

• Hydraulic Fluid:  Through the single prop valve, the prop can be filled with
  a 2-4% oil-in-water emulsion.

• Foot Extensions:  Foot extensions, produced out of aluminum, are available to offer
  f1exibility in the lengths of the props.  There are two standard sizes:  300mm and 500 mm.
  

• Filling the Prop:  The prop is extended by means of a setting pistol.  It is designed for
  one-hand operation with automatic pressure relief during closing.  Filling and withdrawal
  connections of all Salzgitter prop types are of uniform design.  The setting pistol can also
  be modified to include an extension which allows the operator to extend the prop from a distance
  instead of directly at the prop.

• Withdrawing the prop:  A steel withdrawal lever is used to withdraw (lower) the prop. 
  It is very important to use only the withdrawal lever to withdraw the prop to ao avoid damage to
  the piston valve inside the single prop valve.

• Single Prop Valve:  THe single prop valve is screwed easily into the prop which allows
  it to be changed out underground.  The valve utilized a two-part design for filling and
  withdrawal operations.  The components in the valve are made of stainless steel and
  galvanized steel to ensure a maximum service life.
