Used to mate HVA 4 inch gate valve to 4 inch ASA flanges or 4 inch ASA Diffusion Pumps. 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

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

ASA ANSI 2 in. Bolt Down Flange with 3/8-16 UNC Threads. Includes Built-In Reed Switch Position Indicators. These HVA brand pneumatically operated series 11000 gate valves are made in the U.S.A and have an ASA ANSI 2 inch vacuum flange with 3/8-16 UNC blind-tapped holes. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. HVA Part Number: 11210-0201R. HVA ASA 2 inch gate valves connect/mate to other ASA flange faces via a special ASA gate valve sleeve and bolt kit, part number: P107353 located on this website. HVA pneumatically operated vacuum gate valves feature a positive lock-over center mechanism which keeps the valve locked closed during loss of power or air pressure. Gate, bonnet, and bellows seals are made of Viton fluoroelastomer (FKM) material. They are made with corrosion resistant 304 stainless-steel gates and valve bodies and have a typical life of 100,000 cycles (depending on the process) before needing service.
