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

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
