Type HT-S rotary valve

Whether your company is active in animal feed, food, recycling, paper, plastics processing or any other industry, there is a good chance of finding an HT-S at work somewhere in your production line. HT-S valves are the workhorses in our valve range. Thanks to our wide range of rotor designs, conversions and options, it is almost impossible not to find the right valve for your situation. The HT-S is used in pneumatic transport for up
to a 0.4 bar differential pressure. But it also proves a powerful dosing valve under silos and bunkers even with abrasive and challenging products, thanks to its heavy rotor construction and external bearing.

Suitable as

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.

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

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.
