special characteristics of our valves
 
Body spherical form, with great transitions radially designed,with surfaces nearly without marks.

 
The seats are hard-cladded according to a technique developped by us.
The flow-stressed internal parts will be surface hardened, grinded and polished.
The internal parts of the contol valves can be replaced.
Silent mode of operation by sound insulating equipment build in.
The best control capability by extremely long spindle stroke.
Multistage controllable reduction at higher differential pressures. 
Long spindle guides, therefore, vibration-free operation.
