This is a SPECIAL sleeve and bolt kit for the HVA 4 inch ASA ANSI Gate valves. Without it you can not connect/mate
ASA flanges to the ASA 4 inch HVA gate valve. The reason for this kit is that the ASA 4 inch HVA gate valve has smaller bolt holes than a normal ASA 4 inch flange bolt hole
and therefore requires a sleeve bushing to line up the bolts. The HVA ASA ANSI 4 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 4" gate valve contains:
- 16 bolts 3/8-16 1 inch Hex
- 16 sleeves
See illustration below for installation of the gate valve.
