Features: |
HYCOA Series 300 Low-Pressure Diversion Valves
are designed and fabricated to provide optimum flow sequencing
control in a wide variety of installations involving working
pressures up to 300 psi (max). These rugged, high performance
valves feature a special interflow design that allows simultaneous
flow to both the discharge ports while the piston is in changing
position. As a result. since there is no "blind" areas
during piston change, high flow volumes can be diverted effortlessly
without putting any shock loads oil either the piping or other
components in the system. HYCOA diversion valves not only simplify
control piping but also provide simultaneous operation
without constant adjustments of pressure, volume or
the stroke valve operators.
NO EXTERNAL ACTUATORS The 1-piece bode of
the Series 300 valve includes an integral actuator that eliminates
the problems of stem leakage, misalignment, and mechanical
linkage failure associated with external actuators.
SIMPLIFIED MAINTENANCE Single-end coupling
design permits quick removal of the valve's wearresistant,
balanced piston for servicing. Valve design also eliminates
internal body packings, and permits both the cylinder seal
and the Nylon main fluid seal to be replaced without
removing the valve body from the line.
REDUCED PIPING COSTS HYCOA diversion valves
help reduce
long-term operating expenses. A single Series 300 unit
can replace two on-off valves, thereby cutting initial as well
as installation and maintenance costs. In addition, when different
port Sizes are needed, this variation call be accomplished economically
during fabrication. shockfree operation also minimizes system
stress loads and the resulting maintenance requirements.
WIDE RANGE OF SIZES HYCOA 3-way diversion
valves are available in two styles: Series 300-F (Full-Flow)
and Series 300V
(Venturi). Full-Flow models are available in standard sizes
ranging from 2-20 inches; Venturi models are supplied in comparable
sizes.

|
NOTE: Nonstandard sizes also can
be supplied on special order. |
|
Applications: Hycoa Diversion
Valves serve a broad spectrum of fluid flow control applications,
ranging from the primary metals market, to automotive, municipal
water service, sewage disposal and water purification. Typically
one HYCOA Series 300 valve can replace two on-off valves
or other less versatile valve designs. |
|
Automotive |
Two to Six inch valves for controlling
flow of coolant in machine tool applications. Typically coolant
is diverted from the machine during "non-machining" portion
of cycle to either the flume or to flush other areas of the
machine. By replacing two traditional on-off valves. the
HYCOA valve enables the Automotive coolant system to:
- Conserve Coolant
- Use smaller coolant pumps
- Eliminate "misting" and "splashing"
- Eliminate
water hammer
- Moderate system shock
|
|
SCARF QUENCHING: |
Only one Series 300 valve is required for
both high-volume quenching and scale removal on scarfing machines.
By replacing (2) on-off valves the HYCOA diversion valve reduces
installation and maintenance costs |
|
ROLL COOLANT SPRAY |
Hycoa 3-way diversion valves are widely used for
roll coolant solution systems. For this application, they usually
are fabricated with one smaller size discharge port.
This asymmetrical discharge configuration imposes
a simulated back pressure approximately equal to that
of the roll nozzles when the coolant flow to the spray
is diverted. As a result. there is minimal effect on the
flow rates or pressures for other roll stands. |
|
FILTER BYPASS |
A Series 300 valve can provide full flow to a filter,
and can be set to automatically divert the flow to a bypass
line at a specified pressure differential. The bypass flow can
be used to "back flush" the filter or to provide relief
for the system until the pressure differential is corrected. |
|
STANDBY DIVERSION |
A single HYCOA Series 300 valve, either manually
or automatically operated, can be used to assure fast, efficient
changeover on pumps, filters and hydraulic systems. |
|
RUNOUT TABLE SPRAYS |
When used as a spray control valve on runout tables,
the Series 300 diversion valve eliminates line shock, gives
rapid, positive closure and provides pump relief as it
operates. A restricted discharge port, when properly sized
as an orifice, will provide proportional recirculation
to the pump. |
|
COKE QUENCHING |
HYCOA 3-way diversion valves efficiently handle
the high volume of water needed for coke quenching. When the
quenching is completed, a small discharge port automatically
recirculates the water, assuring positive protection for
the pumps. |
|
TUBE QUENCHING |
Series 300 valves are ideal for supplying
fast response and high volume low pressure flow required
for tube quenching |
|
PUMP RELIEF |
Series 300 valves can provide protection for
large centrifugal pumps and simultaneously maintain maximum volume
and pressure in the work area. |
|
MANIFOLDING |
The special interflow design of HYCOA diversion
valves allows fabrication as clusters. |
|
Materials: |
Body - Fabricated from Schedule 160 ASTM A-524
Grade II seamless pipe, internally hardchrome-plated and honed. |
Piston Rod & Seats - Stainless Steel (AISI 303) |
Seals - End Buna-N (Nitrile) |
Seat - Nylon GS (Note: Viton Seals available for
special media requirements. |
Pressure - Working (Max) - 300psi
@ 100° F |
Sizes - Series 300-F (Full-Flow)
models: 2 to 20 inches; Series 300-V (Venturi) models in a comparable
but smaller range because of design configuration. Fabricated
design permits 360° orientation for ports and may variations
in port sizes are available to meet special requirements. |
|
Special Note: In addition to 3-way diversion valves,
HYCOA produces 2-way automatic shutoff valves that have the same
basic design and operating features, including high-response
balanced pistons, as the diversion models. |
