HVA High Vacuum HV Manually Operated Gate Valve ISO-F DN 63 Flange, Viton Gate and Bonnet Seals, 304 Stainless Steel, 11110-0253. ISO-100 Bolt Down Flange with M8 x 1.25 Threads. HVA Part Number: 11110-0253.These HVA brand manually operated series 11000 gate valves are made in the U.S.A and have an ISO-F DN 63 vacuum flange with M8 x 1.25 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: 11110-0253. 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 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.

Bolt Kit for ISO-F DN 63 Gate Valve with Threaded Hole Flange, Includes 4 Silver Plated M8 x 1.25 x 20 mm Long Bolts and 4 Stainless Steel Washers. These bolt kits consist of 4 hex head, silver plated M8 x 1.25 bolts, 20 mm long, and 4 stainless steel flat washers. They are properly sized for connecting ISO-F 63 hole through flanges and fittings to the threaded holes in ISO 63 gate valves. Gate valves have standardized flange, thread, and thread depth specifications. These bolt kits are correct for connecting any gate valve of this flange type and size to an unthreaded flange of the same size, no matter the manufacturer. A centering ring with O-ring seal is required and sold separately (part number P101761). The length of the bolts in this kit are specially measured so they tighten ISO-F to ISO-F flanges fully but don’t bottom out in the blind threaded holes of the gate valve’s flange. The bolts are silver plated to prevent galling or seizing of the bolts and to make them easier to loosen, especially if they have been heated to bakeout temperatures. If the gate valve is to be connected/adapted to an ISO-K type flange, such as might be found on a turbo pump, single claw clamps with longer bolts and centering rings are required.

ISO DN 200 Centering Ring, for Sealing of NW-200 Vacuum Flanges, Aluminum with Viton® O-Ring (FPM) ISO-LF Flange Size: NW-200 Common Dimensions:A = 8.38" (213.00 mm) B = 0.15" (3.9 mm)

ISO 250 Centering Ring, NW-250 Vacuum Flange Size, Aluminum with Viton® O-Ring, Typically Used with 10 Inch O.D. (254 mm) Tubing. These ISO DN 250 centering rings are made of aluminum with durable Viton® (FPM) rubber O-rings and are used to seal both ISO-K and ISO-F vacuum flanges. These centering rings follow vacuum technology standards as described in DIN 28404 and ISO 1609. The centering ring which contains a rubber elastomeric O-ring forms the vacuum seal between the two mating ISO-K or ISO-F flange faces. ISO-K fittings are quick to assemble using claw clamps (please see figure - click to enlarge) and can be connected together in any orientation. The claw clamp hooks into a ridged groove in the back side of the ISO-K flange. ISO-F fixed flange vacuum fittings are different and have a bolt circle where bolts align the two flanges. These ISO 250 centering rings are commonly used to build process vacuum plumbing and systems for industrial standard and high vacuum applications.
