Description
General
Willamette VMC-2200 Cone Valve is a plug type valve with a full circular waterway through the body
and plug in the open position. Basically, the valve consists of a body, plug, cover, operating mechanism
and actuating unit. The plug is tapered and fits into the tapered body; it has a central bore of the same
nominal diameter as the connecting pipe. The plug lifts, rotates 90 degrees and then lowers into
position when the valve is operated. This lifting action minimizes seat wear and ensures a long life.
Body & Plug
The valve body has integral Monel seats around the bore. The plug has seats of the same material as
the body seats. This construction provides positive protection for the seats at all times, assuring a long,
maintenance-free life.
Torque Unit (Valve Operating Mechanism)
The operating mechanism, totally enclosed in a separate housing outside of the valve, is easily
accessible for shaft packing adjustment, inspection, maintenance or replacement without shutdown of
the pipeline. The operator is equipped with an external valve position indicator. Bearings are provided
on the top and bottom of the plug to fully support the plug away from the body seats during rotation.
During the operating cycle, the valve operator lifts the plug until it is clear of the body seats, rotates the
plug 90 degrees and finally lowers the plug into full seating contact. The axial movement of the plug on
opening and closing practically eliminates all sliding contact between seating surfaces and reduces
wear to an absolute minimum.
Handling and Storage
Lifting the valve improperly may damage it. Do not fasten lifting devices to the
actuator, plug or through
the seat opening of the body. Lift the valve with
slings, chains or cables fastened around the valve
body, or fastened to bolts or
rods through bolt holes in the flanges.
If installation will be delayed, place valve indoors in secure, weather tight storage. If temporary outside
storage is unavoidable, make sure a vermin proof rain cover (water shedding tarp, etc.) is secured
around/over the equipment to keep off rain and mud. Skid and set the assembly on a flat, solid, and
well drained surface for protection from ground moisture, runoff and pooled rain water.
