FLUSH BOTTOM PENSTOCK
Flush bottom penstock design is used wherever a
continuous smooth opening is desirable. Typical
installations include wastewater setting tanks,
aeration tanks, and sedimentation and flocculation
basins.
The advantages of this penstock is to prevent the
rubbish stay or block at the slot between the bottom
of the penstock and the mounted wall. This is used
for preventing the gate operation stuck and water
leakage cause by the stuck at the bottom gape.
This penstock is providing a flat plane across the
bottom of frame while the gate is open by using the
EPDM seal. The seal is mounted to the frame with
stronger support by corrosion resistant fasteners.
The EPDM seal is design for easy replaceable without
dismantle the frame. Bottom wedges are not used
with a flushbottom closure.
FLOW
ADVANTAGES:
• Lowest leakage requirement up to 100 times better
than BS 7775:95 standard for bronze seated
penstock.
• 6.0m On/Off seating head and more.
• Come with flush bottom seal.
• Resistant to thermal and general chemical attach.
FEATURES:
High resistant resilient seated (EPDM) penstock generally
used when lowest leakage is required. Good performance
at 10.0m head water. Couple with plastic for better
operation movement.
PERFORMANCE :
This penstock having the lowest leakage rate for off-
seating head close to 0 leakage for 10.0m head of water
pressure. This is excellence Perfomance Penstock and
having lowest leakage rate much more better than BS
7775:95 standard requirement. Trisuria penstock series
has been design and tested to withstand both on-seating
and off-seating heads for standard 6.0m head.
APPLICATION :
Trisuria penstock EP series with resilient seats is having
the same safety factor with typical heavy duty penstock.
The only different is replace the bronze seal to EPDM seal
and plastic seal to achieve the lowest leakage requirement.
The tapered design at sealing surface to provide additional
wedging action and to minimize the wear of the seal.

GeneralThe Trisuria also provide the stainless steel penstock/slide gate in
heavy duty and medium duty application. Stainless steel is design
for non-corrosive water treatment facilities, sewage treatment
plants, water diversion projects, drainage and many other fluid
control installations. Generally, stainless steel penstock is design
for medium water head and zero (0) leakage rate performance.
The EPDM resilient rubber seals provide the highest leakage
resistance with long life duty cycle. Although, stainless steel
penstock having the low head limitation, Trisuria Heavy duty
stainless steel series (SS-H) can double up the head level with higher
leakage resistance as well. The structural design and leakage
requirement is accordance with JKR20200-0108-01 specification
which is also meet the requirement of AWWA C-501:1992 and BS
7775:1995.

Penstock Receiving• Check all parts of penstock and the accessories immediately after receive from the delivery.
• Penstock is a precision machinery items that should be handled accordingly. Those improper storage
and handling can cause the poor performance of penstock.
• During penstock handling, penstock must support by full length to avoid the structural twisting.
• Penstock must store in clean and dry environment to prevent distortion.
• Cover all equipment to protect machined surface. Do not stack equipment without protection.
• DO NOT DISASSEMBLY the gate during installation. Do not paint bronze and stainless steel surface.
Existing Headwall Installation Method• Box out the concrete foundation bolt and spigot end where applicable on request.
• Mark the center line of the aperture onto the template, after that mark the frame bolt hole and then
drill the hole from where it’s mark.
• Then, fix the J bolt to the drilling position and then mount the template into the position by aligning
the vertical and horizontal leveling.
• When the template position is correct, fill the box out pocket with non shrink grout until it fully cure.
Steel packingpieces
Box out forfoundationbolts
Recess forspigot
• When the grout is fully cure, remove the
template and penstock can be installed. Before
mounting, a steel packing piece insert to all the
bolt. These space allowance is for sealing
purpose. When tightening of the bolts and nuts,
special care to avoid over tightening of the nuts
and best if apply even tighten force.
• After penstocks has been mounted, check the
alignment before sealing penstock wall gap.
Check the door and frame faces with feeler
gauge. Double check the bolts and nuts to make
sure that the tightening is not over tight causing
strain to the penstock frame. Finally, penstock
frame gap can be sealed after finish the above
checking procedurals. If all the recommended
installation method are following, the penstock
should be operate correctly without leakage
problems.

New Headwall Installation Method• Secure all anchor bolts in proper position in
the forms, check the size, projection, and
alignments conform to requirements shown
in our illustration. Do not mount penstock
to the misaligned bolts.
• Each bolt has been provided with 2 nuts for
proper mounting of penstock. In
setting the forms, provide a recess around
the perimeter of the gate. Allowing easy
adjustment of the back nut and make sure
the sufficient grout space must be left for
adjustment of the back nut.
• After concrete has been poured and form has
been stripped, place one nut on the anchor
bolt. P lace the completely assembly
penstock into position carefully. Place the
second nut on the anchor bolt and bring bolt
nuts into f inger-t ight contact with the
penstock’s frame, aligning it as necessary.
Figure #1.
• Check the clearance between gate and
frame by the 0.1mm feeler gauge. If find out
some gaps, check to see if penstock has
been warped during install. Adjust the nuts
to bring the penstock into flatness.
Figure #2.
• After the penstock is properly set, grout in
the space between frame and headwall
using a non-shrink material. Figure #3.
Check for voids carefully.
• Tighten all nuts uniformly. Do not over
tighten cause the uneven surface. Penstock
now is ready for initial operation. Figure #4.

Procedure for Installation On Wall Thimble or Pipe Flange.• Place the thimble correctly in position. Plumb is used to align the top/bottom center line.
Mark the center line and install the thimble either flush or slightly projecting from the wall
• Thimble need support to prevent warpage during concrete pouring. Do not mount penstock
when thimble are not cast with concrete.
• All tap hole must be plug by mild steel or other plug before pouring concrete.
• Double check on the vertical and perpendicular alignment of thimble before casting concrete.
• Gate frame need to clean before installing. For better sealing, a thin coat of mastic or
rubber compound is apply on the front face of the thimble.
• After all the procedurals complete, mount the penstock to the thimble. Tighten the nuts on
the stud or screw uniformly until metal to metal contact is made. After checking the clearance
with 0.1mm feeler gauge, the penstock is ready for operation.
Procedure for Installation Stems and Stem Guide• After the installation of penstock is complete, install the stem to the penstock and thread
the stem into thrust nut in the nut pocket on cover until flush with bottom of nut.
• Tighten the set screws to lock the stem for the rising stem.
• Mount the stem guides from bottom up as stem is install. In this moment, do not tighten
stem guide assembly bolts.
• Tighten the stem guide bracket to the wall with the spacing provide.
• Install the stem couplings as required, tighten all the set screws of the stem couplings.
• Make sure not to bend or damage the stem and threads during installation.
Procedure for Installation Headstock Mounting Bracket:• Headstock bracket mount by the anchor bolts to the wall. Check the top surface and make
sure is align perpendicularly with the stem is pass through the center of the stem slot.
• After the headstock bracket is install completely, put on the headstock on top of the bracket
and mount with four bolts and nuts.
• Make sure the headstock is in proper alignment all the time.
• After install the headstock, apply the tension to the stem by lifting the penstock. Align the
stem guides and tighten the stem guide assembly bolts.
Cleaning and Adjusting• After installation of stem, stem guide, and headstock, move the gate to fully open position.
• Clear all the dirt, paint, etc. off of seating and wedging surfaces, and clean loose concrete
and grout from top of gate.
• Grease seating and wedging surfaces with water resistant grease. Close the gate and the
penstock is ready for operation.
