Warren Controls 2800 Series Istruzioni per l’uso

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

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.
