Valves are often damaged in the throat
area by corrosion or steam cavitation.
Now you can eliminate remove/replace
downtime and expense by repairing the
worn valve while you leave it in-line.

The Model VM6000 Portable Valve
Repair Machine makes on-site repair of
a wide range of valves practical. With
the VM6000, you remove the valve
bonnet assembly to allow access to the
valve throat, machine a weld prep
groove, apply a weld build-up as
necessary in the eroded area. in the
eroded area, and bore out the valve
throat to original dimensions.

Capabilities

The Model VM6000 is a “generic” valve
repair machine that mounts on and bores
the throat area of any valve the mounting
fixtures can attach to. Using three mount­ing ring sizes, the VM6000 mounts directly
on valves with outside flange diameters
from 3.5 - 17 inches (88.9 - 431.8 mm). It
machines inside diameters from 2.5 - 13
inches (63.5 - 330.2 mm). The VM6000 is
capable of boring inside diameters, turning
outside diameters, undercutting, and
cutting recesses and grooves.

Features

The VM6000’s power head long ago
proved its rugged dependability in our
Model FF12 portable flange facing
machine. The 1.2 hp (0.90 kW) pneumatic
motor and gear reduction provide
plenty of torque for remachining valves.

The mounting fixtures, which form a
sturdy base, mount directly on the valve
to align and center the unit. Two
different tool heads provide access to
any inside and outside diameter within
the standard 2.5 - 13 inch (63.5 - 330.2
mm) range.

Axial feed is via automatic power feed
(optional digital readout available). The
power feed unit can be quickly removed
if you want manual feed for tool
positioning. Automatic radial feed is
incorporated in both tool heads and
allows cutting of recesses and grooves.
The small tool head feeds the tool
radially at 0.0025 or 0.005 inches
(0.0635 or 0.1270 mm) per revolution.
Automatic tool stop allows cutting to a
preset diameter.

Setup and operation

To set up the VM6000, attach, center
and align the proper mounting fixture
components. Insert and center the
power head/spindle and align it in the
valve. Once the VM6000 has been
aligned it can be removed and replaced
without disturbing the alignment.

VM6000 Valve Repair Machine

For cutting weld prep grooves, remove
the machine from the mounting fixture
and adjust the tool head using the
bench gauge/fixture.

Once the cutting diameter and preset
stop are set on the tool head, insert it
in the power head spindle and replace
the VM6000 in the valve. The machine
is now ready to machine a weld prep
groove to a preset depth. When boring,
the radial feed is disengaged, the boring
diameter is set using a micrometer and

the boring depth is controlled manually.
Depth of the bore is determined by
visual inspection or optional digital
readout.

After corroded material and old
weldments are removed, take out the
VM6000 and apply weld buildup as
needed. Finally, reattach the VM6000
and remachine the valve to manufacturer's
original specifications. There is one tool
holder for each of the three standard
machining operations.

Digital readout option

The VM 6000 Valve Repair Machine is
available with or without a digital
readout control unit. The digital readout
control unit allows precise boring to a
predetermined depth without visual
inspection.

VM7000 Valve Repair Machine

page 5

If the valve was welded in-line, eliminate
rewelding and recertification by
remachining in place. By eliminating
downtime and spare valve inventory
costs, you can probably pay for the
Model VM7000 by repairing just a few
valves in-line.

Capabilities

The Model VM7000 is designed to
mount directly on safety valves and
rework nozzles up to 4 inches (101.6
mm) in diameter. The VM7000 will
mount on Dresser Consolidated
Maxi-Flow valves, orifice sizes 1 through
6, and on many Crosby Safety Valves.

Any safety valve with a similar
configuration can be repaired with the
VM7000 (optional modified mounting
fixtures may be needed). Combine the
various tool bits and tool holders to
remachine valve bushing seats to the
manufacturer's original specifications.
Machine outside diameter, inside
diameter, and bushing seat faces to
close tolerances.

Features

The VM7000 consists of a compact
pneumatic power head and spindle, a
set of mounting fixtures, and tool heads
for a range of machining operations.

The power head features a 1.2 hp (0.90
kW) pneumatic motor that drives a
worm gear reduction, for plenty of
torque at the tool head. The spindle
turns in ball bearings to ensure smooth
operation.

The tooling assembly consists of the tool
head, the tool set fixture, the boring and
facing heads, and the tool bits. A draw
bolt holds the tool head to the spindle.
The tooling assembly does three basic
valve remachining operations: boring,
turning and facing.

The VM7000 mounts on the valve with
a fixturing assembly that consists of
mounting fixtures, adapter rings and
clamp bars. The adapter ring, machined
to fit standard valve bore sizes, centers
and aligns the machine in the valve
opening. The adapter ring raises the
machine slightly above the flange
surface to ensure alignment with the
valve axis, even if the valve face is
uneven due to corrosion. The valve
mounting fixture uses existing valve
flange studs.

Now you can repair a safety valve in about
the same time it would take to remove the
damaged valve.

Setup and operation

To set up the VM7000, pick the proper
adapter ring and put it in the valve's
counterbore. The upper surface of the
ring will be slightly above the surface of
the valve face.

Next, choose the proper mounting
fixture and put it on the valve. The
adapter ring will automatically center the
mounting fixture. Rotate the mounting
fixture to fit the slots to the valve studs.

Once the mounting fixture is set up, the
power head with attached tool head
goes into the mounting fixture bore and

is bolted in place. With the proper head
and tool bit in place, you can do facing,
boring and turning operations. Vertical
feed is controlled manually. The vertical
adjustment dial is calibrated in 0.001
inch increments.

To start a cut, turn the vertical feed
crank clockwise until the tool just begins
to cut and the vertical adjusting dial is
zeroed. Then cut to the valve
manufacturer's specified depth. A tool
set fixture is provided with the machine
to give a reference point for determining
the cut diameter.

Optional tool gage set

To ensure a perfect tool setup, Climax
offers gage block sets that allow exact
tool positioning every time. The gage
blocks are precision machined to match
the valve nozzle manufacturer's original
specifications.

VM8000 Valve Repair Machine

page 8

Sometimes it's economical to replace
smaller valves, but it's usually more cost­effective to repair the larger sizes.
Maintaining an inventory of replacement
valves to keep your system operating
would be prohibitive. Using portable
machine tools to repair valves in-line,
you save all the expense of replacement
valve inventory, weld reinspection, recer­tification, and the downtime necessary
to complete the job.

With the Model VM8000 Valve Repair
machine, the repair operation consists of
removing the valve bonnet and stem
assembly, applying a weld build-up as
necessary in the corroded valve seat and
seal areas and remachining to the
manufacturer's original specifications.
The original in-line welds are not dis­turbed and need no recertification.

Capabilities

The VM8000 is designed for on-site
remachining of seats and seal areas of
Fisher and Dresser Masoneilan (or any
other, similar type) control valves. The
machine mounts directly on the valve
and bores throat areas from 2.5 - 10
inches (63.5 - 254 mm) in diameter. Also
reface seats up to 0.75 inches (19.05
mm) wide without tool bit adjustment.
The machine can reach 16 inches
(406.4mm) from the top to the valve
body and has a boring stroke of 10
inches (254mm).

The machine cuts nearly any kind of
finish from fine to 40-pitch scroll for
gasket seals.

Features

Components of the VM8000 include a
main body, rotational drive unit, turning
bar, mounting fixtures and tool holder

set. Machining torque is delivered
through the rotational drive unit, which
may be either hydraulically or pneumati­cally driven. The axial feed system is
manually controlled. Calibrated in 0.001
inch (0.0254 mm) increments, the feed
dial can be zeroed to cut precise depths
specified by the manufacturer. Boring
diameter is set with the manual hand
wheel on top of the bar. Make multiple
boring passes without removing the
machine for tool adjustments.

Pin locators in the mounting plates allow
accurate repositioning of the machine's
main body during multiple setups.
Because the turning bar rotates in close­tolerance needle bearings, the machine
is capable of high precision machining.
During boring operations, total indicated
runout (TIR) will not exceed 0.002 inches
(0.0508 mm) over the entire stroke.

With the long turning bar, deep valve
machining is possible. The rack-actuated
tool head radial feed is automatic at 0.003
inches (0.076 mm) per revolution, or
manual at 0.025 inches (0.635 mm) per
revolution.

Precision machining is achieved with the
calibrated radial feed dial located on top
of the turning bar.

Setup and Operation

Remove the valve's bonnet and stem
and mount the Model VM8000 base
plate. Attach, center and level the
intermediate plate and main body
assembly. Cut the necessary weld preps,
making sure old weldments and all
corrosion is removed. Remove the
VM6000 and apply weld buildup as
needed. Using the pin locator system,
the machine is reattached to the
intermediate plate in perfect alignment
for finish machining all seat and seal
areas. The tool bit remains visible during
machining operations so the operator
has excellent control of all precision
boring and facing operations.

Repair corroded seal areas on-site with
the valve in-line.
