Additional Design & Technical Notes:
Sizes 2" through 6" utilize a unique scallop
design that permits dual pressure service
(150/300). These sizes t properly between
any ANSI Class 125/250 or ANSI Class
150/300 anges. Sizes 8" through 12" are only
rated for ANSI Class 150 service. The bolting
pattern for ANSI Class 125/250 and ANSI
Class 150/300 are the same, respectively.
Valves are for liquid service only. They should
be installed at least ve pipe diameters
downstream from any turbulence producing
components.
Resilient soft seats are also available. Please
contact factory for price and delivery.
