VDL Rotary Valves

VDL Industrial Products has been a well-known manufacturer of "HT" rotary valves for more than 40 years. The experience and know-how gained in different fields of application, throughout these years, give the rotary valves HT the good reputation they have today. The simple basic design shows off in low maintenance costs, and therefore these rotary valves are economically very interesting, for contractors as well as for end-users.

With the experience gained over the years and with regard to the positive benchmarks of the existing HT series, recently our engineers developed our new medium duty MD range. These valves are especially built and tested for dosing- and pneumatic conveying of powders and granulates.
