HVA High Vacuum HV Manually Operated Gate Valve ASA ANSI 2 Inch Smooth Flange, Viton Gate and Bonnet Seals, 304 Stainless Steel, PN: 11110-0201 . ASA ANSI 2 in. Bolt Down Flange with 3/8-16 UNC Threads. HVA Part Number: 11110-0201 . These HVA brand manually 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: 11110-0201 . NOTE: 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 manually operated vacuum gate valves feature a positive lock-over center mechanism with gate, bonnet, and bellows seals of Viton fluorelastomer (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. HVA valve bodies have one of the smallest interior surface areas in the vacuum valve industry. The body and all major internal components are vacuum furnace brazed at 1100°C at 1x10-6 Torr using a proprietary process which ensures maximum joint integrity, minimizes outgassing during operation, eliminates the possibility of virtual leaks or entrapment areas, and minimizes body distortion found in conventionally welded valves. HVA gate valves with ASA, ISO, or KF flanges are rated for high vacuum applications and are limited to ultimate pressures in the 10-8 Torr range due to O-ring gas permeability. HVA gate valves have a helium leak rate of 1.5 x 10-10 Torr l/sec and are bakeable to 150 °C (with the valve open or closed). Repair kits are available for all HVA gate valves we carry. HVA gate valves are often used in combination with cryo, turbo, diffusion, and ion high vacuum pumps. They are available in high vacuum and ultra-high vacuum varieties in the following sizes: Quick flanged sizes KF-16, KF-25, KF-40, and KF-50 ISO LF flanged ISO-63, -100, -160, -200, -250, -320, -400, and -500 sizes ASA ANSI sizes 2, 4, and 6 inch sizes Conflat (CF) 1.33 , 2.75, 3.375, 4.5, 6, 8, 10, 12, 13.25, and 14 inch sizes The installation manual and operating instructions are available in the downloads.

This is a SPECIAL sleeve and bolt kit for the HVA 4 inch Gate Valves PN 11210-0401R (pneumatic) or PN 11110-0401 (Manual). 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 16 sleeves See illustration below for installation of the gate valve.
