Note: |
1. Safe connection
of all
actuators to valve due to direct mounting Interface acc.
to DIN 3337 No interruption
of valve stem to actuator!
|
2. Reliable stem sealing
by V-rings, made of PTFE and equipped with spring washer
|
3. High frequency of operations
by means of special primary sealing system
|
4. Precise mounting
by fully
centred guidance of screws; connection of the center
section to
the flanges in the correct position
|
5. Stem in anti blow-out design
the ball surface is super-polished and absolute round
|
6. Safe sealing
to the
outside, guaranteed by fully encapsulated body seal
|
7. High degree of tightness
in bore due
to the special form of the seats. The prestress of
the seats causes a spring effect, which results in a reliable
sealing function in all pressure ranges.
Materials:
PTFE/Glass, R-PTFE, PEEK, VESPEL
