1. Torques based on 100 Mpa induced stress
infastener threads.

2. Values are based on steel bolting well
lubricated with a heavy graphite and
oilmixture.

3. For cadmium plated fasteners multiply
torque x0.75.

4. For zinc plated fasteners multiply torque
x1.40.

5. Recommended torques are a minimum.
Formaximum torque multiply torque x 1.05.

INSTALLATION

The valves are shipped with flange surface
protection. Before installing the valve, remove
the protection.

CAUTION

The valve should be installed in the slight open
position whether the gap between disc edge and
body flange face is about 10 mm to insure that the
seat and disc are not damaged during installation.
Particular care should be taken with valves
equipped with "single acting" actuators.
Failure to insure proper handling may result
indamage to the valve.
If the pipe is lined, confirm that the disc rotation
does not contact the lining during the opening
stroke.
Failure to confirm that the disc rotation dose
not contact the lining may result in damage
tothevalve.

The Figure 129/239/139 valves are
bi-directional and will control flow equally well
in either direction.

CARRIAGE AND STORAGE

1. Carriage

The valve shall be carried safely not to be
impacted or affected by other object.
Especially, the wheel of operator and disc edge
shall be protected by any means.

2. Storage

The valve shall be stored in the higher place
which is able to prevent from being submerged
in water and keep off from penetration of
rainwater or cover it with waterproof cloth,
which Keystone valve LLC. does not provide,
toavoid being wetted.
When worker installs the valve, remove
the dust and extraneous substances after
disassembling the pallet and protective cover.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Installation in new construction using welding
type flanges

1. With the disc in the slight opened position,

align and center the companion flange bolt
holes to the body alignment holes (Figure
239/139) or lug holes (Figure 129).

2. Assemble the body and flanges with the

flange bolting and make-up the bolting.

3. Using the flange-body-flange assembly for

fit-up and centering to the pipe.

4. Tack weld the flanges to the pipe.

5. Remove the flange bolting and valve

assembly from between the flanges.

CAUTION

Do not finish weld the flanges to the pipe with the
valve bolted between the flanges as this will result
in serious heat damage to the valve seat.

6. Finish welding the flanges to the pipe and

allow the flanges to cool completely before
proceeding.

MAINTENANCE

Routine maintenance or lubrication is not
required.

Dismantling the valve from pipe (Figure 5)

1. Be sure that the fluid and pressure in
valve and pipe must be removed before
dismantling.

2. Close the valve.

3. Cut off the supply of the electric power,
hydraulic or pneumatic pressure depending
on the kinds of operators attached and
disconnect the electric cable, hydraulic or
pneumatic hoses.

4. Release the flange bolt in order to
disassemble the valve assembly.
Disassemble the operator ahead when
necessary.

5. Dismantle the valve after open the flanges
sufficiently using tools.

6. Disassembly the operator in the condition of
fastening the valve assembly on vise.

WARNING

Make sure that the fluid and hydraulic or
pneumatic pressures in valve, operator and pipe
are removed, and then dismantle the disc in the
position of full close after taking safety measures.

FIGURE 3

Be sure to be familiar with following facts
before installing.
Tie up with rope when handling the butterfly
valve assembly for Figure 129/239/139.

1. Tie up feature with rope when handling
the valve assembly vertically. (Figure 2)
Liftthevalve in the condition of tying upper
neck with ropes. Tie up the front and rear
side of valve with two ropes, because the
rope may be removed when use one rope.

2. Tie up feature with rope when handling the
valve assembly horizontally. (Figure 3, 4) Lift
the valve in the condition of tying upper and
lower neck with ropes. Beware that the rope
on the lower neck may not be removed or
valve assembly may not be tilted.

DANGER

Use the rope made by synthetic fiber only
taking into account of valve weight and safety
andpayattention that paint on the valve does not
peel. When worker lifts the valve assembly, which
is equipped hand wheel including gear box, in the
condition of tying hand wheel with rope, he(she)
shall comply with the specific method which
manufacturer provides because the stem may be
distorted or the cover may be damaged.
