Type MD-EX Rotary valve

Are you looking for a rotary valve that can be used in an EX environment, but which also has higher pressure differences of up to approx. 1 bar? The MD-EX rotary valve range offers you a suitable solution. These very robust valves combine a high degree of filling with minimal product damage due to their construction, so that a smaller valve is sufficient. Maintenance friendliness has also been taken into account right from the design of the MD valve, through the use of, among other things, maintenance-free external ball bearings and adjustable stuffing box gaskets, a direct flange drive, an easily detachable rotor and standard PN 10 connection flanges.

The MD-EX rotary valve is certified according to the ATEX regulations according to EX II 1D/...
Externally, either a certified ATEX II 2/3D drive or an non-zoned motor can be chosen.

Suitable as

The MD-EX is the best choice for heavy duty applications, with difficult flowing products up to 1 bar pressure difference.

Pressure shock resistant up to max. 2.5 bar (PU blades 1.7 bar)
