Butterfly Valves In is featured with a unique style of the neck designs,
for accommodation of various pipe designs, piping positions and installation environment.
SPECIAL FEATURES ABOUT THE VALVES
- Easy valve- to- flange centering: Due to Light weight of the valve body
(Which is only one third of KITZ’s conventional cast iron body butterfly valves)
eases valve to flange centering work on mounting valves in pipelines
- Wide range of service applications: Austenitic stainless-steel disc is
used in order to have highest corrosion resistance, which give the valve best durability
across a wide range of applications to be used.
- Stabilized Operating Torque: A pair of stem bearing assembled around the
top and bottom stems prevents stem galling and stabilizes valve operating torque
for smooth and trouble free disc rotation.
On the spot actuator assembly: The actuator mounting pads of all valve necks
are designed in conformity with ISO 5211 requirements for direct on site mounting
Prevention of Dew Condensation: A long stainless steel neck blocks transfer
of the fluid heat to a valve operating device, which thus needs no insulation on
the operating device. Dew condensation is minimized also in case of gear operated
valves on cold water service.
- Rust Prevention: Main parts such as stems, discs, necks, neck connectors
and endplates, small parts such as stopper plates, washers and bolting’s are all
made of stainless steel for highly graded rust prevention.
- S- shape spherical disc for high sealing performance(patented): KITZ’s
original cross sectionally S- shaped valve discs with spherical surface evenly make
tight contact with rubber liners for excellent sealing performance with reduced
operating torque. Thorough 360 degree shut off mechanism helps extended service
life of rubber liners. (Size- 2” and above).
- Elaborately designed KITZ EPDM seats: EPDM seats are featured with many
unique functionalities like-
High sealing performance
Long life cycle
Self- reinforcing back- ribs- to minimize valve operating problems such as distortion,
skidding and exfoliation of rubber liners caused by line pressure load and friction
with metal discs.
Wider disc seating contact
Dual stem seal bearings- are assembled on top and bottom stems for stabilized sealing
Gasket less flange sealing contact for easy valve mounting.
