ControHeat Jackets Cover Valves
CSI makes ControHeat Bolt-On Jackets forvirtually any valve. Generally, there are twotypes of jacket construction offered: Onepiece jackets, called UniJackets, for valves
sizes 3-inch and smaller; and two-piece
jackets for valves sizes 4-inch and larger.
Very large valves like 20-inch gate valves
may utilize more than two pieces toaccommodate ease of installation.

Here’s How The
ControHeat Jacket Works:
1. Pressurized heating fluid enters thepressure chamber embedded in thealuminum casting.The pressure chamber may be either carbon steel or stainless steel.

2. The pressure chamber is designed,manufactured and tested in accordance with the ASME Boiler andPressure Vessel Code, Sec. VIII, Div.1.

3. The aluminum casting, which nevercontacts the pressurized heating fluid,
rapidly transfers heat from thepressure chamber to the externalsurface of the valve.

4. Normally, heat transfer cement is usedwith the jacket to minimize any air gap
between the casting and the valve
body. The cement promotes efficientheat transfer.

Typical Two-Piece
ControHeat Valve Jacket

Control valves withintegral jackets often
require very long lead times fordeliveries. Sometimes the longdelivery times force instrument
engineers to sacrifice performance foravailability. ControHeat Jackets allow you to selectthe optimum valve for the process without concern
for the jacket.

with flanged
connections andextended coverage formating flanges is used in
650°F service on a 20-inch ballvalve in a polymer reactor operation.

Any ControHeat Valve Jacket can be designed toheat mating pipe flanges as shown on these plug
valve jackets used in BPA service.

This UniJacket on an off-the-shelf sampling valve
keeps the valve plug-free, ready to operate
at all times.

Three-way ball valves are easily heated with
ControHeat Jackets. Various styles of actuator

ControHeat Jackets for Pumps
ControHeat Bolt-On Jackets are widely usedthroughout the processing industry to improvepump efficiencies, prevent motor
burnout andpromote uniform processing temperatures. Somecritical metering pump
applications require jacketing to assure accurate
throughput. Certain gearpump applications require
jacketing to minimize
degradation of polymers
and other products that are
shear sensitive. The barrels ofprogressive cavity pumps may need to be4

heated for foodstuffs such as chocolate,syrups and dairy products. In some batch-type
operations, pumpjacketing may beneeded during
start-up only. In
pumping applications
like sulfur, phthalicanhydride, or DMT, notonly does the pump casing need to be heated at alltimes, the backplate also may needheating. When pump manufacturers do notoffer jacketed backplates, CSI offers bothfabricated bolt-on heating jackets as well
as ControHeat Jackets.

ControHeat Jackets for Meters & Instruments
Accurate process dataand process performance often depend
on instruments, metersand safety devices operating at elevated processtemperatures. CSI makes jackets for many types of meters,
instruments and related equipment:
DP cells, vortex shedding meters,
rupture discs, coriolis flow meters,viscometers, tank vents, level indicators

process. Jacket is hot-oil heatedand maintains meter at 600° F.

and chemical tees. Few of these components
are available with integral jackets. The
ControHeat Jacket has a history of
successful service with thesecomponents. In fact, several
manufacturers of theseproducts havestandardized on theControHeat Jacket
to complement
their product lines.

ControHeat Jackets keep the passages clear.

Pulsation Dampeners with
ControHeat Jackets in hightemperature applications provide
critical service for downstream
instruments and meters. The jacket
keeps the stagnent process fluid
under the dampener’s gas padmolten.
