| |
| Resilient Seated Gate Valves (Conform to BS 5163 Type B) |
| |
Advantages &
Technical Features
1. Inside screw non-rising stem wedge gate type.
2. 12mm lead acme thread stem reduces turn to open & close the
valve.
3. Drop tight closure under full pressure.
4. Low operating torque.
5. The gate may be removed without removing the valve from the
pipeline.
6. Stem "O" ring seals can be replaced with
the valve in the fully
open position &
under pressure.
7. No seating recesses for gate maintain
smooth, unobstructed waterway &
eliminates
the accumulation of debris.
8. The straight through full bore will prevent pressure loss caused by
turbulence.
9. The fully EPDM vulcanise rubber gate gives excellent resistance to
corrosion.
10. All valves are supplied with support feet.
11. Fusion bonded epoxy coated (350 microns) for protection against
corrosion.
Operation & Control Mechanism
The valves are suitable for a variety of operation e.g. T-key or Ring key &

TVT Ductile Iron Double Flange Butterfly
Valves are conform to BS EN 593 with
internal body resilient lining suitable for
waterworks purposes.
Advantages &
Technical Features
1. Designed for Bi-directional flow, smooth
function is ensured in operation and also
during opening & closing.
2. Low head loss and greatly discharged
characteristics.
3. It will provide positive tight shut off
at the fully closed position (90 degrees)
but also
at an angular tightness of 5
degrees off the fully closed position.
4. Eliminates the use of gaskets between the
valve and adjoining pipe flanges.
5. The valves are suitable for mounting in
any position.
6. Disc are available in various materials
such as ductile iron nickel plated,
aluminium
bronze, stainless steel, titanium
steel and carbon steel.
7. Wide selection of materials, applicable
for various medium.
8. The gearing and bearings are protected by
water tight enclosures permanently packed
with grease.
9. Lifting lugs are provided (350mm - 2000m)
for easy lifting, handling & installation
at
site.
10. Opening and closing indicators are
provided.
11. 600mm and above valves are supplied with
support feet.
12. Cold applied high solid epoxy resin (350
microns) coated for protection against
corrosion.
Operation & Control Mechanism
The valves are suitable for a variety of
operation e.g. Level handle, manual gearing,
electric, hydraulic, or pneumatic actuators. |

TVT
twin door wafer check valve is an improved
version of the conventional swing check and
the single disc is split in two. By
splitting the disc in two, the mass of the
single disc is greatly reduced and so is the
travel distance from open to shut off
position. Further improvement results with
torsion springs forcing the double disc to
shut off with minimal flow reversal. This
shut off characteristic greatly minimizes
the slam potential as compared to the
conventional swing check.
Features
1. Compact structure, light weight & low
cost.
2. Easy to install & maintain.
3. Two torsion springs are used excerting on
each of the pair valve plates, which close
the plates quickly and automatically.
4. The quickly close action prevents the
medium from flowing back and eliminates
hammer effect.
5. Safe and reliable in operation, high
interference resistance.
6. Low head loss.
7. It is easily install between standard
flanges with gaskets using only one set of
flange
studs.
8. The valves are tightly sealed with no
leakage under the pressure water test.
9. Suitable for vertical or horizontal
installation.
10. The face to face dimensions are in
accordance with ISO5752-82.
11. Short face to face length enabling
installation in restricted spaces not
possible with
conventional flanged check
valves.
12. The connections dimensions of flanges
are according to the standards of BS 10
Table
E, BS4504 PN 10, PN 16 & JLS 10K. |
