KSB is one of the leading manufacturers of industrial valves and pump technology, especially for energy and water applications. As an Armaturenfabrik, we combine KSB’s quality with our engineering expertise: we not only supply standard products, but also configure complete systems – including modification, automation and documentation.
For reliable shut-off in piping systems – in various designs and materials.
For precise control of liquids and gases.

The strainer ECOLINE FY 40 is free of non-ferrous metal, and the paint finish is temperature resistant up to 400 °C.
The DANAÏS 150 extends to DN 1200 (NPS 48), the ISORIA to DN 1000 – also usable as an end-of-line valve.
We trade in KSB valves and supply plant engineering, maintenance and operators directly from the manufacturer range. The overviews below show the series we supply regularly and recommend for the respective application – they are a selection, not a limit. We can source the complete KSB range, including series not listed here. Enquire with the type designation, nominal size and pressure rating, and we will check availability and delivery time.
The design determines the pressure rating, temperature range and nominal size. Centric, soft-seated valves are the economical solution up to PN 16 and +200 °C; with these, only the disc and the liner are in contact with the medium. Double eccentric valves go beyond that – higher pressure ratings, larger nominal sizes, lower temperatures and a metal seat as an option.
| Series | Design | Nominal size | Pressure | Features |
| BOAX-S (wafer) BOAX-SF (threaded lugs) | centric, soft-seated | DN 20 – 600 | 16 bar up to DN 200, 10 bar from DN 250 to 600 | body in ductile iron JS1030, disc 1.4301 / 1.4308, liner in EPDM or nitrile; spherically machined disc, up to DN 250 with a lock against unintentional adjustment |
| ISORIA 10 / 16 | centric, soft-seated | DN 40 – 1000 | PN 10 and PN 16 respectively | −10 °C to +200 °C, vacuum down to 0.3 bar absolute; liners in nitrile, EPDM XA, EPDM XC (suitable for drinking water) and EPDM XV (heat-resistant); five body designs from T1 to T5 |
| DANAÏS 150 | double eccentric | DN 50 – 1200 (NPS 2 – 48) | PN 10 / 16 / 25 and Class 150 | usable from −50 °C; seat in plastomer, elastomer or metal |
Recommended flow velocity for the ISORIA: 1.5 to 3 m/s with water.
The stem sealing is the decisive criterion. A gland packing can be serviced and adjusted. A bellows seals the stem hermetically and is the choice with heat transfer oil, with steam and wherever leakage to the outside has to be ruled out – for example under the German TA Luft clean air regulation.
| Series | Stem sealing | Nominal size | Pressure rating |
| BOA-Compact | gland packing, body in grey cast iron | DN 15 – 200 | PN 6 / 16 |
| BOA-H | bellows, body in grey cast iron | DN 15 – 300 | PN 16 |
| NORI 40 ZXL / ZXS | gland packing | DN 10 – 400 | PN 25 |
| NORI 40 ZXLF / ZXSF | gland packing | DN 10 – 200 | PN 25 |
| NORI 40 ZXLBV / ZXSBV | bellows | DN 10 – 200 | PN 25 |
In the NORI 40 family the suffix denotes the version: BV marks the bellows, F the version with a flanged connection, and ZXL and ZXS distinguish the body material.
| Series | Nominal size | Pressure rating | Features |
| Check valve series 2000 | DN 8 – 80 (¼” – 3″) | PN 16 | body in CF8M, −10 °C to +200 °C, compact wafer design |
| Check valve BOA-R | DN 15 – 300 and DN 15 – 350 respectively | PN 6 / 16 and PN 16 respectively | for liquids and gases that do not attack the valve materials |
| Check valve BOACHEM-RXA | DN 15 – 400 | PN 10 – 40 | −10 °C to +400 °C – the version for hot and chemically loaded media |
| Strainer BOA-S | DN 15 – 400 and DN 15 – 300 respectively | PN 6 / 16 and PN 16 / 25 respectively | body in EN-GJL-250 up to 300 °C or EN-GJS-400-18-LT up to 350 °C; standard screen with a defined mesh size and wire diameter for each nominal size |
| Strainer ECOLINE FY 40 | DN 15 – 300 | PN 40 | screen insert in stainless steel, materials free of non-ferrous metals, paint finish RAL 7038 up to 400 °C |
| Diaphragm valve SISTO-16 | DN 15 – 300 | PN 16 | −10 °C to +160 °C, low-dead-space design for media carrying solids and for aggressive media |
Our standard is the unchanged series version from the KSB range. Where the installation situation requires it, adaptations are possible – as a supplement to the trade, not as a precondition:
Yes – special materials, actuators and special connections are possible. The focus is on supply from the KSB range.
For energy, water, chemical, food and industrial plants.
Yes, on request we supply KSB valves as a ready-to-install assembly with actuator and documentation.
We first review the operating data, materials and connection dimensions, then select the appropriate version from the KSB range. On request we add accessories and documentation.
Because of the high reliability, quality and specialization in energy and water technology – and our experience as a partner.
