These will be integrated into our online store step by step in the future. Until then, please ask us directly for the product you need.

Pinch valves with different pipe connections


Our pneumatic pinch valves can also be ordered with different pipe connection combinations if required.
Select the connection variant you need for each side of the pinch valve and can thus react optimally to any situation.

Choose your combination from the following connection variants:

  • Flange (DIN / ANSI) (Hygienic / Aseptic)
  • Internal Thread (DIN / ANSI, ASME)
  • Tri-Clamp (Row A / Row C) (Hygienic / Aseptic)
  • Weld-on End (DIN / ASTM)
  • Threaded Spigot (DIN) (Hygienic / Aseptic)

Knife gate valves from AKO Armaturen

Knife gate valves


In addition to the large number of pinch valves, we also offer a range of flat slide valves in a wide variety of designs.
Beside knife gate valves type A, B & C you can also ask us directly for other types of gate valves.

Knife Gate Valve (Type A)

The knife gate valve (type A) is a wafer type valve for a wide range of industrial applications. It is uni-directional and is available in standard sizes from DN 50 to DN 1200.
Equipped with flanged connection according to EN 1092 PN10 or ANSI B16.5 (class 150). Expandable with a variety of accessory options (PDF).

Knife Gate Valve (Type B)

The knife gate valve (type B) is an intermediate flanged valve which is best suited for media with high consistency. In contrast to the knife gate valve type A, the knife-gate valve type B is bi-directional and can be supplied as standard in the nominal widths DN 50 to DN 600.
Equipped with flange connection according to EN 1092 PN10 and ANSI B16.5 (class 150). Extendable with accessory options (PDF).

Knife Gate Valve (Type C)

The knife gate valve (type C) is an intermediate flanged slide valve with one-sided sealing for free-flowing and dry bulk materials. It is therefore ideally suited for use as a silo outlet slide valve.
Available in DN 50 to DN 600 with flange connection conforming to EN 1092 ON10 or ANSI B16.5 (class 150). Also expandable with accessory components (PDF).
