Certified Safety: Shut-Off Valves Certified by TA Luft, AD2000 & PED
Our flanged shut-off valves not only comply with common DIN standards for face-to-face dimensions (EN 558-1) and flange connections (EN 1092-1) but also possess a range of crucial certifications. These include:
- TA Luft: Ensures compliance with strict emission limits, ideal for environmentally conscious industrial applications.
- AD2000 / AD2000-A4: This German regulation certifies that our valves meet the high requirements for pressure equipment.
- PED 2014/68/EU: Certifies conformity with the European Pressure Equipment Directive.
- Fire Safe: Certifications like API 607/API 6FA prove the safety of our valves in case of fire.

Industrial Applications – Every Medium, Every Challenge
Isolation valves and fittings from Fergo are at work in plants for the following sectors:
- Steam and hot water
- Chemical and aggressive media
- Oil and gas pipelines
- HVAC (Heating, Ventilation, and Air Conditioning)
- Food & beverage and pharmaceutical production
- Energy management and supply
For specialised requirements that standard solutions cannot meet, we also offer custom-engineered systems. And if you need more practical examples or want to delve deeper: the Fergo Blog is full of expert knowledge and industry insights.

Gland Packing or Bellows – This is what the Right Seal Looks Like
When absolute leak tightness and low maintenance are required, it pays to take a closer look at the sealing technology. This is especially crucial for emissions control. The typical designs are:
- Globe Valve with Gland Packing: Our proven classic relies on high-quality graphite gland packings. These withstand high temperatures (up to 400°C) and are suitable for a wide range of media.
- Globe Valve with Bellows Seal: The ultimate in terms of tightness and emission control. Virtually maintenance-free and the first choice when maximum safety is critical.

Shut-off valve for steam: What you need to consider
Shut-off valves for steam systems must withstand particular stresses. High temperatures, thermal cycles and the aggressive nature of steam require a special design.
For steam applications, we recommend valves with a robust design and suitable material combinations. Our flanged shut-off valves made of 1.0619 steel are designed for maximum operating temperatures of up to 400°C. The graphite gland packing ensures reliable sealing even at these temperatures.
Before purchasing, always check the approved temperature range and maximum operating pressure to ensure a long service life and trouble-free operation.

FAQ – Your questions about shut-off valves
While a gate valve is primarily designed for the ‘fully open’ or ‘fully closed’ function, a globe valve (also known as a poppet valve) is ideal for precise flow control. The design with an axially moving disc allows for sensitive throttling of the medium.
A bellows valve is always the first choice when leaks at the spindle must be absolutely ruled out. This is the case with media that are hazardous to health, harmful to the environment, valuable or highly pure. The bellows protects the spindle from the medium and the environment from the medium.
Yes, absolutely. Specially designed shut-off valves for steam are designed for high temperatures and pressures. Look for materials such as 1.0619 steel and sealing components that are approved for steam applications. We will be happy to advise you on this.
TA Luft (Technical Instructions on Air Quality Control) is a German regulation that sets strict limits for emissions from industrial plants. A valve that is ‘TA Luft-compliant’ has a gland packing (usually made of graphite) that complies with these strict emission limits.
