Body
Streamlined design and smooth finish of the body provides minimum resistance to flow.
Disc
Streamlined and low profiled disc ensuring higher Cv values. Double offset disc design reduces seal
wear and torque.
Sealing System
Sealing on seat face is ensured by an endless T profile resilient sealing ring which is held on the
periphery of the disc by a retaining ring. In closed position of disc the resilient sealing ring is pressed
against the cone shaped seat face of the body and provide safe sealing in either direction of flow. In
opened position of disc, sealing ring is completely unstressed due to the double eccentric disc design.
One piece retaining ring prevents sealing ring from rolling out. Sealing ring can be replaced easily at
site without dismantling the valve disc and without any special tool requirement.
Shafts
Stub shaft design provides small restriction of the passage.
Shaft Connection
Positive disc to shaft connection by the help of key.
Bearing System
Self lubricating plain bearings reduce shaft friction and operating torque. These bearings keep the
disc in center and prevent axial movements.
Shaft Sealing
Double O-ring shaft sealing system ensures maintenance free sealing for life span.
Top Flange
All butterfly valves are equipped with ISO top flanges for all types of actuator- operator connections.
Lifting Holes and Feet
Integral lifting holes provide easy installation and feet ensure strong ground support.
Body Seat
Stainless steel weld filled and finished integral body seat ensures a corrosion, erosion resistant seat
face.
Coating
Fusion bonded epoxy, Two pack epoxy, Solvent-free epoxy, Coal tar epoxy.

Butterfly ValvesDouble Eccentricity
The first eccentricity (e1) brings the axis of rotation outside the sealing axis. That's why full circle
sealing between body seat and sealing ring is achieved. The second eccentricity (e2) brings the
axis of the disc from axis of the valve. By the help of second eccentricity the sealing ring is off
seated after only a few degrees of movement at open direction. The purpose of the second
eccentricity is to quickly relieve rubber seal compression in the area of the disc shafts to eliminate
rubber scruffing and abrasive wear.
When the valve is open, the rubber is completely unstressed, so that no permanent impression
is retained, even if the valve remains open for years.

OPERATIONOPTIONS
DESIGNPROPERTIES
TK Range worm gear operators have been designed and developed by Z-KAN for the
operation of Butterfly valves. Worm gear operators offer a quarter turn (90) motion that is
required by butterfly valves and disc motion is limited at open, closed positions by traveling
nut system
Bottom end of the worm shaft is threaded and a nut moves up-down on this threaded spindle.
When operating the gear (valve) in open or close direction, the traveling nut also moves
towards the corresponding end stop and prevents the over travel of valve disc.
Self locking (irreversible) gear design guarantees the proper operation and tightness of Z-
KAN butterfly valves.
Nine types of worm gear operators cover the torque requirements of whole range of butterfly
valves.
Worm or worm/spur gear operators are so designed that butterfly valves can be operated by
one operator.
Robust design
Factory set 90 swing angle. Setting of the end stop by traveling nut system
Strong, integrated into the body valve attachment
Valve attachment according to ISO 5211

The operation method of these valves is a combination of the hydraulic operated
butterfly valve and of the hydraulic damped check valve.
Valves are opened by actuating the hydraulic cylinder and closed by the help of
heavy counter weight. Valves are equipped with hydraulic powerpacks.
These valves are specially designed for the smooth operation of pumps and can
also be used for other applications that require a fail safe closing or opening
function.
A suitable sensing/tripping device must be connected to valves powerpack and
control board for the required function.
Combined Check
- Valve opens automatically when the pump starts and closes automatically
before the pump is stopped.
- In case of power failure at pumping station, valve closes like a hydraulic
damped check valve.
- Both opening and closing times are adjustable.
- The hydraulic powerpack is also equipped with a handpump for emergency
opening of valve.

The overspeed/pipe burst control valves are installed in pipelines where a pipe
burst could create a danger to the system and environment.
These are automatic closing safety valves which are designed to close the valve in
case of an overspeed flow is detected.
Overspeed is detected by the detection system. In case of excessive flow, counter
weight is released automatically and disc starts to close. Closing speed can be
adjusted.
Valve is opened manually by the help of a handpump. When the full open position is
reached, valve is hydraulically locked by the oil pressure in the cylinder.
