This is a SPECIAL sleeve bushing and bolt kit for the HVA 2 inch Gate Valves PN 11210-0201R (pneumatic) or PN 11110-0201 (Manual).
Used to mate HVA 2 inch gate valve to 2 inch ASA flanges or 2 inch ASA Diffusion Pumps.

This is a SPECIAL sleeve and bolt kit for the HVA 2 inch ASA ANSI Gate valves. Without it you can not connect/mate ASA flanges to the ASA 2 inch HVA gate valve. The reason for this kit is that the ASA 2 inch HVA gate valve has smaller bolt holes than a normal ASA 2 inch flange bolt hole and therefore requires a sleeve bushing to line up the bolts. The HVA ASA ANSI 2 inch Gate Valve has 3/8 inch threaded holes and the sleeve and ASA flange has smooth holes.

This SPECIAL sleeve and bolt kit for the HVA ASA ANSI 2" gate valve contains:

8 bolts 3/8-16 1 inch Hex
8 sleeves

See illustration below for installation of the gate valve.
