Heavy Duty - 2400 Series

Shan-Rod fabricated butterfly dampers are designed to give long, trouble-free service in all low pressure service applications. The versatility of fabricated dampers allows Shan-Rod to design the damper to your specifications as required by your systems.

DESCRIPTION
The basic damper consists of a fabricated carbon steel body furnished with flanges drilled for bolting to rolled angle companion flanges or with no drilling for thru bolting between 125/150 ANSI flanges (wafer) design, fabricated carbon steel disc, 304 stainless stub end shafts, graphitar lantern gland, lubricated stuffing boxes with alemite purge fittings, conventional swing thru seat design.

CORROSIVE AND HIGH TEMPERATURE SERVICES
Shan-Rod dampers are in service in many corrosive and high temperature applications such as sulphur oxides, flue gases, thaelic anhydride, blast furnace gases, sinter fumes, cupola gases, coke oven gases, humid acetone gases, toluene vapors, gas turbine exhausts, brackish water, salt water, catalyst fines. Temperatures at 2200°F. Shan-Rod engineers select the most compatible materials and coatings for services as described above to supply the industry with a damper that is maintenance free for many years

Operation & Special Construction
SHAN-ROD fabricated valves can be operated by manual lever, handwheel or chainwheel; power actuated by diaphragm, piston, cylinder or electric; with auxiliary declutchable handwheel or chainwheel available.

STUFFING BOX

Power End - Standard with carbon bushings requiring no lubrication for trouble free operation. Packing can be replaced without the removal of lever or actuator.

Blind End - Same as Power End except with no packing

SPECIFICATION GUIDE
When ordering specify: size, type of fluid, specific gravity, temperature, maximum pressure, maximum flow differential pressure at shut-off, valve action (fail open or fail closed), flange ratings, accessories, pipe run.

Other standard sizes available in increments of two inches, or valves can be custom made to customer specifications.

Do not use for construction purposes unless dimensions are approved.

*Shaft may be vertical, if end of valve opposite power end is down (vertical thrust bearing or washer is required).

MAINTENANCE
SHAN-ROD valves require a minimum of maintenance, depending on service conditions. Stub shaft bolted to disc with 304-SS bolts allows easy shaft and disc removal. Inboard bushings do not require lubrication, thereby saving time. If service is dirty or corrosive, use of optional teflon bushings or outboard bearings is recommended. Lubricated and/or purged stuffing boxes should also be employed. All parts are easily replaced in field and, if required, are available from local sources since materials of construction are standard.
As we are continually developing our products, the design of SHAN-ROD valves is subject to change without notice.
