2. DESIGN ANALYSIS
All valves manufactured in V‐Tork are
designed, developed & manufactured by
complying the relevant international
manufacturing standards.
Valve are designed by multidimensional
approach like theoretical calculations,
numerical simulations (FEM & CFD) &
prototype validations.
Design tools used are AutoCAD, Solid
Works, MathCAD.
For adequate and accurate results,
valves are analyzed based on the fluid
interactions over the valve body to
examine the structural and safety life
performance of the valve.
4. CYCLE TEST
ORMANCE TEST
V‐Tork validate all products
and ensure the soundness of
the product by performing
various tests such as NDT,
Chemical
&
mechanical
properties along with hydro
tests
Reliability of valve operation affects
service life and maintenance. To predict
reliability, a sound valve design, backed
up by a stress analysis must be subjected
to functional cycle testing under critical
operating conditions for which V‐TORK
carried out cycle test for specific model.

Spark Testing apparatus
rocedure: When the metal reinforced rubber sleeves
are placed and the spark tester torch is run aroun
d the sleeves, observe the sparks produced during
the process.

29.

Spark Test
Observation:
If the metal and rubber are well‐bonded, the sparks produced will be c
onsistent and relatively uniform. However, if there's poor or no bondin
g between the metal and rubber, the sparks might show irregular patt
erns or interruptions, indicating potential separation between the two
materials.
Conclusion:
We are doing spark test as per sampling plan since the suppliers are s
elf certified. We have now implement the testing procedure to check a
ll the sleeves (100%) to ensure the bonding

Quality Assurance on Rubber Sleeves
All rubber sleeves are tested to meet V‐Tork standards.
Rubber vendors are evaluated every 6 months.
Rubber sleeves are molded in batches, with test
buttons from each batch stored at the factory.

roved Wear Resistance:
Polyurethane is known for its exceptional wear resistance p
roperties. The polyurethane knife gate valves offers superio
r resistance to abrasion, erosion, and chemical attack comp
ared to push‐through sleeved valves. This makes them well‐
suited for handling abrasive or corrosive fluids, reducing th
e need for frequent maintenance or replacement.
Valve features with a thick gate design to withstand under e
xtremely abrasive slurries which improves the valves for ma
ximum wear life

Unique One Piece Urethane Cartridge:
Unique one‐piece precision moulded high strength polyurethane cartri
dge protects the wetted parts from corrosion and abrasion. The replac
eable polyurethane cartridge is a robust seat seal in severe slurry
services.
r Maintenance Requirements:
he wear‐resistant properties of polyurethane Knife gate val
s contribute to longer service life and reduced maintenan
needs.
olyurethane knife gate valves require less frequent mainte
ance, and no flushing resulting in cost savings and increase
operational efficiency.
ower total cost of ownership compared to sleeved valves d
e to lower repair cost.
nife gate Valves that don’t have a liner must be fully refurbi
ed or replaced once they begin to show wear. However, V
ORK’s B‐450, the cartridge can simply be replaced. This giv
the V‐TORK’s B‐450 an extended life and cost advantage c
mpared to other type valves.

V‐Tork is very keen to satisfy ou
customers to study their requir
ment and to provide a solution
rather to sell the existing
products.

CASE STUDY
Push through design valves supplied to a steel plant in India as per the
requirement of client specification. Client was not willing to change their
specification during quote submission.
ALLENGES:
perational difficulties
edimentation of media
amage of Stem
amage of sleeves
ROOT CAUSES:
•Lack of Flushing
•Non Removal of Bottom Dummies
VATION & SOLUTION
on the site assessment it was understood that the valves
t flushed and maintained properly. Hence the media got
ed inside the valves and that leads to the cause of damage
ves. It was concluded that the customer is unable to flush
ves and they require a no maintenance valve without flus
ystem. Hence we recommended the Polyurethane lined
gate valves (B‐450) and the same has been installed at site
erforming well.

CONCLUSION
In summary, the choice between polyurethane‐lined knife gate valves
and push‐through design sleeved valves depends on the application
and maintenance suitability. If you are willing to make for your specifi
c application. Polyurethane‐lined knife gate valves are durable than p
ush through and suitable for abrasive or corrosive media but may hav
e a higher initial cost but the down time of plant can be reduced dras
tically..
hrough design sleeved valves is an economical choice but may
e more frequent maintenance.
