MODEL
100-01KO
(Full Internal Port)
Anti-Cavitation Hytrol Valve
• Virtually Cavitation Free Operation
• Severe Service Design - High Pressure Differentials
• Reduced Noise and Vibration
• 316 Stainless Steel Disc Guide and Seat Standard
• Drip-Tight, Positive Sealing
• Service Without Removal From Line
• Retrofit to Standard Hytrol Valves
The Cla-Val Model 100-01KO Anti-Cavitation Hytrol Valve is designed for applications where there is a high potential for damage from cavitation. Specify this
valve series for a wide variety of control valve applications having pressure differentials up to 300 psid or for relief valves having atmospheric discharge up to
150 psid.
The 100-01KO Hytrol main valve provides optimum internal pressure control
through a unique anti-cavitation trim design. Constructed of 316 Stainless Steel,
the seat and disc guide trim components feature dual interlocked sleeves containing radial slots that deflect internal flow to impinge upon itself in the center of
the flow path, harmlessly dissipating the potential cavitation damage. This
unique design also lessens the possibility of fouling if large particles in the water
are present due to the large flow path of the radial slots.
The 100-01KO Hytrol is the basic valve used in Cla-Val Automatic Control Valves
for high differential applications requiring remote control, pressure regulation,
solenoid operation, rate of flow control, or liquid level control.
The Anti-Cavitation Trim components can be retrofitted to existing valves if the
application indicates an appropriate need. Please consult factory for details.
Principle of Operation
On-Off Control
Full Open Operation
When pressure in the
relieved to a zone of lower pressure,
the line pressure at the valve inlet
opens the valve, allowing full flow.
cover chamber is
On-Off Control
Tight Closing Operation
When pressure from the valve inlet
is applied to the cover chamber, the
valve closes drip-tight.
Modulating
Control
Modulating Action
The valve holds any intermediate position when operating pressures are
equal above and below the
diaphragm. A Cla-Val “Modulating”
Pilot Control will allow the
valve to automatically compensate for line pressure
changes.

Cla-Val Control Valves with KO ANTI-CAVITATION Trim operate with maximum efficiency when mounted in horizontal piping with the main valve cover Up. We recommend isolation valves
be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be considered essential. A regular maintenance program should
be established based on the specific application data. However, we recommend a thorough inspection be done at least once a year. Consult factory for specific recommendations.

100-01KO Hytrol Main Valve with Anti-Cavitation Trim Purchase Specifications
C
Function
The valve shall be hydraulically operated, single diaphragm actuated, globe pattern. The valve shall consist of three major components: the body with seat installed, the cover with bearing installed, and the diaphragm assembly. The diaphragm assembly shall be
the only moving part and shall form a sealed chamber in the upper portion of the valve, separating operating pressure from line pressure. Packing glands and/or stuffing boxes are not permitted and there shall be no pistons operating the main valve or pilot controls.
Ductile Iron is standard, other materials shall be available. No fabrication or welding shall be used in the manufacturing process.
Description
The anti-cavitation features of the seat and disc guide detail shall have flow slots equally spaced around their perimeters. The seat slots shall be
orientated around the perimeter of the seat so that fluid entering the valve shall flow through the seat slot detail such that the fluid flow converges
in the center chamber of the seat allowing potential cavitation to dissipate. The disc guide slots shall be positioned around the perimeter of the
disc guide, configured and oriented in an angular direction so that fluid flow exiting through the slots is diverted away from direct impact into pressure boundary surfaces. Flow exiting the disc guide slots is directed in an angular path to increase the distance between the slot geometry and
pressure boundary surfaces. If cavitation conditions exist, the increased distance between the slots and pressure boundary surfaces minimizes
the potential for damage by allowing the cavitation bubbles to dissipate before they come in contact with pressure boundary surfaces. Anti-cavitation characteristics shall be controlled by the described slotted seat and disc guide components. The disc guide shall slide in the seat and allow
controlled flow through the seat slots into the central seat chamber where flow shall continue from the seat chamber and exit through the angularly oriented slots of the disc guide. The seat and disc guide features used together shall provide anti-cavitation characteristics suitable for applications where a large controlled pressure drop is desired.
The flexible, non-wicking, FDA approved diaphragm shall consist of nylon fabric bonded with synthetic rubber compatible with the
operating fluid. The diaphragm must withstand a Mullins burst test of a minimum of 600 psi per layer of nylon fabric and shall be cycle
tested 100,000 times to insure longevity. The diaphragm shall be fully supported in the valve body and cover by machined surfaces
which support no less than one-half of the total surface area of the diaphragm in either the fully open or fully closed position.
The valve seat in six inch and smaller size valves shall be threaded into the body. Valve seat in eight inch and larger size valves
shall be retained by flat head machine screws for ease of maintenance. The seat shall be of the solid, one-piece design and shall
have a minimum of a five degree taper on the seating surface for positive drip-tight shut-off. Pressed-in bearings and/or multi-piece
seats shall not be permitted.
To insure proper alignment of the valve stem, the valve body and cover shall be machined with a locating lip. No "pinned" covers to
the valve body shall be permitted. All necessary repairs and/or modifications other than replacement of the main valve body shall be
possible without removing the valve from the pipeline.
The valve manufacturer shall warrant the valve to be free of defects in material and workmanship for a period of three years from
date of shipment, provided the valve is installed and used in accordance with all applicable instructions. The valve manufacturer shall
be able to supply a complete line of equipment from 1
1
⁄4" through 48" sizes and a complete selection of complementary equipment.
