Water
Available headworks for water are quarter-turn ceramic headworks (standard) and EPDM headworks (NBR75 90SH).
The taps have standard removable 1/2" nozzles and 1/2" inlet male connection threads.
The sealing is with EPDM.
Vacuum breakers are optional, to prevent sucking polluted water into the waterworks.
Maximum working pressure for the water taps is 10 Bar.

Special water
Demineralised water should not come into contact with Brass. For this, three options are available:

• Nickel plated taps
  The standard brass taps can be provided with a nickel plating (thickness 17 Microns), which makes them suitable for demineralised water. The advantage of this option is that a wide range of shapes is available. To order, simply add "NK" to the standard article number.
  Synthetic headworks (PES) are used.
  
• Brass tap with internal tube
  A few models are available with an internal tube (PVDF). The water is only in contact with EPDM and PP. Synthetic headworks (PES) are used.
  Taps for ultra-pure water are also available (constant circulation).
  
• PVC taps
  Steendam supplies a small range of taps made of PVC, which can be used in many occasions. The taps are not vandal-resistant which means they are not suitable for schools etcetera. Operation with PVC ball-valve (open-close)
  

Natural Gas
Taps for natural gas are supplied with a push-turn ceramic headwork. -Apart from the gas taps with ceramic headworks, a range of taps with a ball-valve is available. Both types are approved by DIN/DVGW.
Maximum working pressure for gas taps with ceramic headwork is 0.2 bar; for ball-valves 10 bar.

Other Gasses
Needle valves are used for other gasses. The needle valve makes fine-control of the flow possible. Sealing is with PTFE. For steam, a sealing of Viton is used.
Taps for Oxygen and Acetylene are supplied with a special grease, to avoid explosion. They have to be ordered separately, by adding "DG" to the article number.
Maximum working pressure for the needle valves is 10 Bar.
