Warren Controls 2800 Series Instructions for use

This document covers the installation, operation and maintenance
of the Series 2800 Precision Globe Control Valves presented in the
“Series 2800 Product Specification”, including the 2820 Two-Way
Single Seat Valve, the 2828 Two-Way Single Seat Low Flow Valve, the
2830 Three-Way Mixing Valve, and the 2832 Three-Way Diverting/
Mixing Valve. Warren Controls Series 2800 Precision Globe Control
Valves feature rugged bronze or stainless steel bodies with a variety
of trim materials and port sizes. The equal percentage and linear
plugs in the 2-way valves and linear plugs in the 3-way valves
provide excellent modulating control of a wide variety of fluids
for pressure, temperature, level, and flow applications from –20 to
500ºF (dependent on contruction). The Series 2800 is ideally suited
where value and long life are important objectives for applications
including but not limited to the Chemical, Food & Beverage, General
Service, Refining, District Energy, and ideal for Pharmaceutical
Industries.

Series 2800 Precision Globe Control Valves are available with a
variety of actuators and accessories. These actuators and accessories
have separate instructions. For complete control valve installation,
operation, and maintenance instructions see also the instructions
for the actuator and accessories in use.
VALVE IDENTIFICATION
To use these instructions it is necessary to identify the configuration
of the valve. Factory assembled control valves have a nameplate
mounted on the actuator. The valve’s part number (P/N) is present
on the plate. The part number represents the configuration of the
control valve. To identify the valve’s type, size, actuator, accessories,
and other characteristics decode the part number using configura-
tion table. If the information is incomplete, incorrect, or not pres-
ent contact the factory with the valve serial number listed on the
plate. (See Information Present on Control Valves section for location
of part number, serial number, and other important information on
valve.)

There is a great deal of information present on each control valve
ranging in importance from the part number and serial number to
the color of the paint and casting numbers. This information is im-
portant for identifying the valve, installing it correctly, and obtaining
parts. Examples of the current factory nameplates and flow arrow
plates used on Series 2800 control valves are shown here. The ac-
companying table identifies the information present and where to
find it on the control valve. There may also be other casting numbers
and foundry marks present that do not provide useful information.
Customer specific tagging may also present. The plates used, and
information present, on Warren Controls other product lines or older
valves may be different, contact the factory for details.

See also separate actuator and accessory instructions for addi-
tional installation guidelines.
• Be sure that the flow medium, ambient temperature and the selected loca-
tion will not exceed the maximum temperature of the valve, actuator, or ac-
cessories. Information can be found in the product specifications and on the
nameplate(s) regarding these limits (See Information Present on Control Valves
section for location of important information on valve).
• Follow good piping practices. Install a bypass around the valve. Install stop
valves in inlet and outlet piping to provide means to isolate valve.
• A straight run of pipe is recommended for 10 pipe diameters upstream of the
valve and 20 pipe diameters downstream of the valve.
• Protect valve and downstream equipment with a self-cleaning strainer.
• Provide proper inlet and outlet drainage in steam service to prevent water
hammer or possible erosion in equipment.
• Install gauges in inlet and outlet piping to provide means for checking adjust-
ment and operation.
• For maximum efficiency and minimum wear install valve in vertical position
with the stem pointing upward.
• Actuators mounted in any position other than vertical must be supported inde-
pendent of the valve.
• Be sure to leave clearance to allow for actuator removal (See Dimensions &
Weights section of Product Specification for actuator removal clearance).
• Before installing, be sure valve and piping are clean inside and free of scale,
chips, welding spatter, and foreign material. Thoroughly blow out or flush pipe
lines.
• The valve must be installed with the fluid flowing in the correct direction(s). For
proper operation in all applications, control valves must be piped according to
the corresponding flow arrows, inlet markings, and port markings present on
each valve (See Information Present on Control Valves section for location of
important information on valve).
• Pipes must be aligned squarely with the valve at each connection.
• If the valve has screwed ends, do not apply pipe dope to the threads of the
valve body or to the first two threads of the pipe.
• If the valve has flanged ends, tighten flange bolts evenly to prevent excessive
stress and the possibility of cracking.
• If the valve has welded ends, prevent plug and cage distortion by keeping ex-
cess heat from the body.
!
Check valve for any
damage due to improper
storage or transportation.
Immediately notify your
sales organization of any
damaged goods upon
receipt. Do not attempt to
move or disturb the valve
further so photos may
be taken. If the shipping
container is noticeably
damaged refuse receipt,
as the shipping company
should be held liable until
a shipping representative
is available to take photos.
INSTALLATION

9
Series 2800 2800_IOM_RevBa_1219
• The valve, actuator, and accessories (if so equipped) are assembled, tested, and
calibrated at the factory. The actuator nameplate specifies set-up parameters
used (See Information Present on Control Valves section for location of impor-
tant information on valve). Do not exceed the supply pressure listed on the
actuator nameplate or you will damage the valve and void the warranty.
• Supply air or voltage, instrument signal, and accessories should be connected
to ports or terminals as indicated on the control valve.
• Final tuning may be required under actual operating conditions.
• On critical or dangerous equipment, provide suitable safety and emergency
systems to protect personnel and property from injury due to a valve malfunc-
tion. If the valve handles flammable, toxic, corrosive or explosive fluids, pro-
vide for safety in the event of valve leakage or malfunction.
• Do not obscure flow arrow plates or nameplates with paint. If flow arrow plates
or nameplates will be covered with insulation, it is recommended the informa-
tion on the plates be transcribed on the outside of the insulation in the same
location as the plate.
OPERATION
• Close inlet and outlet stop
valves.
• Check that valve responds
through rated travel in re-
lation to changes in input
signal. Rated travel is shown
by position of travel indica-
tor on valve stem relative to
travel indicator on yoke.
• For valves fitted with a
handwheel, manually oper-
ate valve using handwheel
through rated travel to
check freedom of move-
ment. Return handwheeel to
its standby position.
• Place valve in operation.

Series 2800 Precision Globe Control Valves are for the most part
maintenance free when properly selected and installed. Rebuild-
ing of these valves should not be necessary under normal operat-
ing conditions. For best operation follow installation guidelines (See
Installation section); maintain the fluid pressure, temperature, flow,
flowing differential pressure, and shut-off differential pressure within
the limits of the valve (See Series 2800 Product Specification for de-
tails). In installations where high vibration exists, pneumatic and/or
electrical connections should periodically be checked for integrity. In
water or water and glycol applications, good water quality must be
maintained or the service life of the valve may be reduced (See Water
Quality Guidelines). The valve stem must be kept free of debris, de-
posits, dirt, dust, and scratches or the packing parts may be damaged
resulting in a packing leak. Control valve hunting will cause excessive
stroking of the valve stem and result in premature failure of the pack-
ing seal. The system must be stabilized to prevent hunting to ensure
reasonable packing life and optimal control performance. Oversizing
of a control valve will result in an unstable condition, which can cause
noise, vibration, and premature trim and packing seal failure. The use
of Warren Controls ValveWorks sizing program will facilitate the selec-
tion of the optimum valve.
MAINTENANCE
PACKING ADJUSTMENT
PARTS/OVERHAUL
Series 2800 Precision Globe Control Valves have either self-adjust-
ing packing or adjustable packing. Valves with Body Material BBronze
and Packing Type TV-ring, VVacuum Service, or LLip Packing have
self-adjusting packing and require no external adjustment. If the valve
has self-adjusting packing and a packing leak is observed replace the
packing and if necessary the stem and plug assembly.
Valves with Body Material BBronze and Packing Type GGraphite have
adjustable packing. Valves with Body Material SCF8M and Packing
Type TV-ring, GGraphite, or VVacuum Service Packing also have ad-
justable packing. If the valve has adjustable packing and a packing
leak is observed, tighten the packing nut ¼ turn and observe. If the
leak continues tighten the packing nut another ¼ turn and observe.
Repeat as necessary. If the leak continues and the packing nut cannot
be tightened further with reasonable force replace the packing and if
necessary the stem and plug assembly.
Damaged or worn parts can decrease performance and shorten valve
life.
Damaged or worn packing parts including the packing, bearings,
spring, and other bonnet parts can cause a packing leak resulting in
damage to the actuator, accessories, and surrounding equipment.
Damaged or worn packing parts can also cause increased hysteresis
resulting in poor control.
Damaged or worn trim parts including the plug, stem, seat ring, pis-
ton, and o-ring can cause increased hysteresis, poor control, excessive
internal leakage, and poor shut-off. Damaged or worn trim parts can
also cause damage to the packing parts resulting in a packing leak.
Damaged or worn body gaskets or o-ring seals can cause external
leakage resulting in damage to the actuator, accessories, and sur-
rounding equipment.
Should parts become worn or damaged, parts kits are available. Re-
pack Kits are available to replace the packing. Repack/Inspection
Kits are available to allow the valve to be opened for inspection of
its internal parts. Rebuild/Repack Kits are available to completely re-
build/ overhaul the valve. Parts kits come with complete step-by-step
instructions. Each kit has its own part number. Please provide the
valve’s serial number to ensure getting the correct kit part number
and correct parts.
