Weld-on design places heating media directly against the valve body for reliable, efficient heat transfer.
-
All welding performed by personnel certified to Section IX ASME BPVC
-
ASME Section XIII Div. 1 used as a guideline for jacket design.
-
ASME Section VIII Div. 2 design by analysis services are available upon request.
-
All jacketed valves are tested on the heating and process side (where applicable) before shipment.
-
Standard Rating: 150 PSIG at 650°F (other ratings available).
-
Standard Materials: U.S. sourced carbon steel, T-304 or T-316 stainless steel. Many other alloys are available.
-
Standard Jacket Ports:
-
½”-2 ½” Valves: ½” FNPT Coupling
-

Full Jacket with Oversized Flanges
-
Design allows the heating media to contact the valve body and flanges within the bolt circle.
-
Utilizes flanges one full size larger than the original valve size.
-
New face-to-face dimension will conform to the ANSI standard for the oversized flanges.
-
Intended to be installed in lines with oversized flanges
Full Jacket with Standard Flanges
-
Full jacket design utilizing standard sized flanges
-
Blind, tapped inserts installed flange bolt holes
-
Design allows the heating media to contact the valve body and the back of the flanges.
-
Intended to be installed in lines with core sized flanges only.
Partial Coverage with Standard Flanges
-
For cases where full coverage is not necessary
-
Only a portion of the valve body is jacketed, flanges are heated indirectly
-
No valve modifications required
-
Design is compatible with many different types of valves and other equipment
