Type HT-S-EX rotary valve

The HT-S- EX rotary valves can be used as air locks in high-vacuum systems and for dosing applications in EX environments. The HT-EX lock is certified according to ATEX regulations according to EX II 1D/...
Externally you can choose between a certified ATEX II 2/3D drive or an non-zoned motor.

Suitable as

Dosing lock under silos and bunkers

For pressure differentials up to max. 0.5 bar and products with normal flow characteristics. For even heavier applications up to max. 1 bar differential pressure, it is better to choose an MD-EX.

Explosion isolation

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

Airlock for vacuum systems

The HT-S-EX dosing valve is very suitable for use as an airlock and economic release system in vacuum systems, in combination with suitable pressure relief.
