Ideal Vacuum UltraLock High Vacuum HV Manually Operated Gate Valve ISO-F DN 63 Flange, Ball Groove Locking, Viton Gate & Bonnet Seals, 304 Stainless Steel. ISO-63 Bolt Down Flange with M8 x 1.25 Threads These Ideal Vacuum UltraLock™ manually operated gate valves 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. Our new UltraLock series of premium manually operated vacuum gate valves are built using an innovative ball-and-groove locking mechanism and have a typical life of 300,000 cycles before needing service. They are made with corrosion resistant 304 stainless-steel gates and valve bodies. All of our UltraLock series of manually operated gate valves include a visible external position indicator - the white ring conveniently mounted below the actuator. UltraLock Locking Mechanism: Our UltraLock high vacuum gate valves employ an ingenious ball-and-groove mechanism to lock the valve. Inside the valve body is a rolling carriage with lubricated ball bearings on which the gate is attached. When the valve is actuated, the carriage and gate are slid towards the vacuum port until the carriage reaches the end of the valve body. This positions the gate concentric to the port. Continued pressure on the carriage causes a set of stainless-steel balls, riding in a decreasing depth groove between the carriage and the gate, to exert outward pressure on the gate. This outward force pushes the gate into its closed position. A leak-tight seal is obtained as the outward pressure forces the gate’s O-ring seal to be pressed against the valve body’s sealing surface. It is common for these valves to achieve an extended life of 300,000 cycles before service is needed. UHV vs HV Versions: Our Conflat CF flanged gate valves are UHV rated. The bellows are welded to the bonnet plate, and oxygen-free, high-thermal conductivity (OFHC) copper sealing gaskets and flange knife-edges form the required metal-to-metal seal between the bonnet plate and valve body. Our Conflat UHV UltraLock valves have a low leak rate of < 3.75 x 10-10 Torr l/sec and are bakeable up to 200 °C with the gate open (150°C with the gate closed). Our KF and ISO-F flanged gate valves use Viton O-rings for the bellows and bonnet plate seals and are therefore limited to high-vacuum (HV) applications with ultimate pressures down to 3x10-8 Torr. KF and ISO-F series UltraLock valves have a leak rate of 1.5 x 10-9 Torr l/sec and are bakeable to 150 °C (with the valve open or closed). Specifications: Our Ideal Vacuum UltraLock gate valves are designed for dependable High and Ultra- High Vacuum (UHV) applications and are often used in combination with cryo, turbo, and ion high vacuum pumps. Available sizes include Conflat CF 2.75, 4.5, 6, 8, 10, and 12 inch sizes; ISO-F DN -63, -100, -160, -200, -250, -320, -400, -500, and -630 sizes; and quick flanged sizes KF-40 and KF-50.

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 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. The ISO standard sizes for large LF flanges are ISO-F and ISO-K DN 63, 80, 100, 160, 200, 250, 320, 400, 500, 630, 800, 1000. These vacuum fittings are made with inner and outer rings of Aluminum 6082 with FPM rubber O-ring material.
