HVA High Vacuum HV Manually Operated Gate Valve ISO-KF NW16 Flange, Viton Gate and Bonnet Seals, 304 Stainless Steel. KF-16 Quick Flange, HVA Part Number: 11110-0063. These HVA brand manually operated series 11000 gate valves are made in the U.S.A and have an ISO-KF NW 16 quick flange (KF-16) vacuum. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. HVA Part Number: 11110-0063. 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.

Ideal Vacuum UltraLock High Vacuum HV Manually Operated Gate Valve ISO NW KF-50 Flange, Linkage Locking, Viton Gate & Bonnet Seals, 304 Stainless Steel. KF-50 Quick Clamp Flange These Ideal Vacuum UltraLock™ manually operated gate valves have an ISO NW KF50 vacuum flange. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. These small manually operated vacuum gate valves are built using a lever linkage locking mechanism. They have a typical life of 300,000 cycles before needing service and are made with corrosion resistant 304 stainless-steel gates and valve bodies. 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 gate 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.
