KÄHLER Plug Valves

The KÄHLER plug valve was designed for systems in which special media place high demands on tightness and resistance to wear and corrosion
and is the perfect solution for precisely shutting-off the flow of fluids and gases in pipework systems, especially in critical applications.

The shut-off valve is characterised by its dead-space-free, robust design, its high physiological safety and its reliability.
KÄHLER plug valves can be safely resealed from the outside at any time during operation.
This unique selling point among the various types of valves is an important element within the design of the valve
and fulfils its function of perfect sealing both internally (in all flow directions) and externally in an amazingly safe and durable manner
and contributes to an almost unlimited service life of the valve.

KÄHLER plug valves are developed in-house.
From planning to production to delivery, they are subject to strict quality control by our qualified team.
We offer more than 100 different variants, covering a wide range of materials and designs.
If required, we are able to develop customised special solutions that are tailored to the specific requirements of our customers,
and thus ensure that you receive the optimum solution for every application.
Compared to other manufacturers, KÄHLER plug valves also impress with attractive delivery times,
an excellent price-performance ratio with the highest quality standards and a reliable after-sales service.

Our plug valves are used in a wide range of applications,
including district heating and cooling supply, industrial and plant engineering, apparatus and pipework construction, the cement industry, chemicals and petrochemicals.
They are particularly suitable for systems where reliability and efficiency are of paramount importance.

Applications KÄHLER plug valve

constructed for many different applications in heating, cooling, oil or gas systems, particularly suitable for difficult applications in industry, the cement industry, chemicals or petrochemicals as well as for systems with long service lives
suitable for all non-aggressive media, such as district heating or cooling water, oil, compressed air, high pressure and gas as well as various chemicals
especially suitable for media containing solids, abrasive or crystalline bodies
operating conditions according to data sheet

Construction KÄHLER plug valve

robust body made of cast iron, steel, stainless steel
straight-lined, compact design even with large nominal sizes
adjustable conical or cylindrical plug made of cast iron, steel, stainless steel, duplex, titanium, Hastelloy or PTFE coated with precise, dead space-free fit in the valve body
one-piece or decoupled design of plug and spindle (depending on model)
