General information

The innervalves are available in 38 different sizes with different characteristics - and about 140 different material combinations. The following features can optionally be selected: Soft seat, double taper. 

Soft seat
All innervalves from V – O are available with PTFE or KEL-F soft seat - thus improving the leakage class of the soft seat.

Double taper
For media with slight impurities. A secondary taper, starting at approximately 75% lift, allows the trim to be flushed of debris without disassembling the unit (the rangeability is decreased accordingly).
