Armaturenfabrik Steam traps Thermal & float-controlled

Steam traps are essential components in steam systems to drain condensate efficiently and safely. They prevent energy losses, protect systems from water hammer and ensure trouble-free operation. Armaturenfabrik offers a wide range of thermal and float-controlled steam traps that offer the highest quality and reliability.

Our recommendation for thermal steam traps

Thermal steam traps are the ideal solution for applications where the amount of condensate fluctuates greatly and high temperatures occur. They are temperature-dependent and use the physical properties of steam and condensate to precisely control the drainage process. These traps are particularly compact, easy to maintain and suitable for use in steam pipes, heating processes and drainage of saturated and superheated steam.

Advantages for thermal steam traps

  • Energy efficiency: Minimizes steam loss through precise control.
  • Robust construction: Made of high-quality materials such as stainless steel or forged steel.
  • Automatic venting: For safe start-up of the system.
  • Wide range of variants: For different pressure and temperature ranges.

Typical areas of application

  • Chemical and petrochemical industry
  • Power plants and energy systems
  • Process steam systems in the food industry

Our recommendation for float-controlled steam traps

Float-controlled steam traps are the first choice for applications with large condensate volumes and low differential pressures. They work independently of the back pressure and ensure continuous and jam-free drainage. Thanks to their robust design and automatic venting, they are particularly reliable and durable.

Advantages for ball float steam traps

  • Independent of back pressure: Ideal for complex steam systems.
  • High throughput: Perfect for high-load areas.
  • Automatic venting: For trouble-free operation.
  • Easy maintenance: spare parts available, no need to remove the pipe.

Typical areas of application

  • Steam systems with high condensate volumes
  • Chemical and pharmaceutical industry
  • Power generation and power plants

Steam traps and plant engineering – Steam traps as system components for SKID units

Armaturenfabrik valves Steam traps, SKID process plants Pipe insulation Angle seat valves and automatic pneumatic control valves

Steam traps are much more than just drainage fittings – they are indispensable functional elements in modern steam, energy and process systems. In SKID systems, they are responsible for the safe, efficient and load-dependent drainage of condensate, thus ensuring trouble-free operation, constant energy efficiency and the protection of sensitive components.


Especially in compact, modular system packages, steam traps must work reliably, handle different pressures and temperatures and be flexibly integrated into any installation situation.
Our steam traps – including thermal versions with diaphragm regulators such as the MK45 from GESTRA – are used as integral system components in SKID and process plant construction and ensure maximum operational reliability even under demanding conditions.
