The GS16DR can be mounted directly to the piping system using the 2 inch (50.8 mm) ANSI flanges.

Consideration must be given to the strength of the piping system to support the 48 kg (105 lb) weight of

the GS16DR.

The mounting interfaces of the GS16DR are designed to support only the weight of the valve itself.

Failure to properly support components (piping, valves, etc.) mounted to the GS16DR can result in

binding loads on the GS16DR body and may adversely affect valve performance.

Refer to ASME B16.5 for details of flange, gasket, and bolt types and dimensions. Verify that the piping

flange-to-flange dimensions meet the requirements of the outline drawings (Figures 1-1 and 1-2) within

standard piping tolerances. The valve should mount between the piping interfaces such that the flange

bolts can be installed with only manual pressure applied to align the flanges. Mechanical devices such as

hydraulic or mechanical jacks, pulleys, chain-falls, or similar should never be used to force the piping

system to align with the valve flanges.

ASTM/ASME grade bolts or studs should be used to install the valve into the process piping. Flange

gasket material should conform to ASME B16.20. The user should select a gasket material which will

withstand the expected bolt loading without injurious crushing, and which is suitable for the service

conditions.
