Industrial valves are among the largest hidden energy consumers in technical systems.
Whether globe valves, ball valves, control valves, basket strainers or complex piping components – without insulation, significant amounts of valuable heat are lost through these components. For more than ten years, Armaturenfabrik Schneider has been offering customized, dimensionally stable and reusable insulation solutions that are now among the most important levers for energy efficiency, safety and ESG compliance.
Why insulation on valves is indispensable
Valves have complex geometries, large surfaces and numerous thermal bridges. Even at process temperatures of 120-180 °C, noticeable energy losses occur per valve, with steam or hot water these losses increase disproportionately.
The consequences:
- Increased energy consumption
- Rising operating costs
- Additional CO₂ emissions
- Temperature losses in the process
- Higher thermal load on the system
Heat losses can be reducedby up to 70 %with high-quality insulating jackets.
A typical DN80 valve loses around 350 W without insulation, but only around 80 W with an IFS-PLAST25 jacket – this corresponds to up to 2,400 kWh per year per valve.
Increasing regulatory pressure – insulation as a mandatory ESG component
With the new CSRD reporting obligation, companies must provide measurable and documentable evidence of energy efficiency measures. At the same time, DIN and EN standards are tightening the requirements for complete insulation – including valves, flanges and filter systems.
The Armaturenfabrik offers:
- Typified, documentable measures
- ESG-compliant verifications
- Measurable savings potential
- Future-proof materials without PFAS
PFAS-free future: Insulation in the changing EU chemicals policy
The European ECHA has proposed a far-reaching restriction of PFAS – fluorinated polymers such as PTFE (“Teflon”) are also affected.
Armaturenfabrik Schneider reacted early and already offers completely PFAS-free insulation alternatives:
Material alternatives at a glance
| material | Temperature resistance | Fire protection class | PFAS status |
| E-glass needle mat | up to 550 °C | A1 (non-flammable) | PFAS-free |
| Silicate fiber | up to 1,100 °C | A1 | PFAS-free |
| PTFE-free outer skin | up to 280 °C | B1 | PFAS-free |
These materials already meet the requirements of the upcoming EU regulation.
Technical solutions from Armaturenfabrik – a perfect fit, robust, easy to maintain
Our insulation solutions are ideal for:
- Butterfly valves and ball valves
- Basket strainer, filter housing, duplex strainer
- Control valves, angle seat valves, control valves
- Pumps and valve housings
- Pipes, steam packs, SKIDs and distributors
IFS-PLAST25 insulating pads and MW20 mineral wool jackets:
- Temperature resistance up to 700 °C
- Non-combustible A1 materials
- Sound insulation and contact protection
- Simple assembly (Velcro, buckles, customized shapes)
- Maintenance-friendly, reusable construction
- Custom-made for every valve
This is precisely why leading companies in the tire industry rely on this valve technology – and why we have been doing so for over 15 years.
Cost-effectiveness: immediate savings, fast payback
Thanks to rising energy prices, demand has increased massively:
| Year | Installations | Energy price index* | Turnover (T€) | Payback |
| 2020 | 1.100 | 100 | 528 | 9-14 months |
| 2022 | 2.050 | 165 | 984 | 5-9 months |
| 2025 | 2.300 | 162 | 1.104 | 5-9 months |
*Index 2020 = 100
For system operators, this means: short amortization period, long-term savings, immediately visible effect.
More than just energy savings: safety & operational continuity
Insulation not only increases efficiency, but also reduces it:
- Risk of burns (contact protection)
- Thermal voltages in the grid
- Risks of leakage
- Downtime due to temperature instability
The result:
higher process reliability, better system availability and extended service life of the valves.
Our claim: Suitable insulation for every fitting solution
As an Armaturenfabrik, we not only offer high-quality industrial valves – we can also supply customized insulation on request:
- For ball valves to reduce thermal bridges
- For control and regulating valves to stabilize the process temperature
- For filter systems for energy reduction and operational safety
- For angle seat valves and steam applications to minimize losses
The result is a complete, energy-efficient system comprising valves + insulation from a single source.
Conclusion: insulation is a strategic success factor today
The combination of rising energy prices, ESG obligations and PFAS regulation makes insulation on valves an indispensable component of modern industrial plants.
Armaturenfabrik Schneider supplies robust, PFAS-free, energy-efficient and economical solutions – precisely manufactured, documentable and future-proof.
