These HVA brand pneumatically operated series 11000 gate valves are made in the U.S.A and have an ISO-KF NW16 quick flange (KF-16) vacuum flange. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. HVA Part Number: 11210-0063. HVA pneumatically operated vacuum gate valves feature a positive lock-over center mechanism which keeps the valve locked closed during loss of power or air pressure. Gate, bonnet, and bellows seals are made of Viton fluoroelastomer (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.

These Ideal Vacuum UltraLock™ pneumatically 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 pneumatically operated vacuum gate valves are built using a lever linkage locking mechanism which keeps the valve locked closed during loss of power or air pressure. These HV gate valves have a typical life of 300,000 cycles before needing service and are made with corrosion resistant 304 stainless-steel gates and valve bodies. Open and closed reed sensor position switches are included. Position sensors can be used to activate indicator lights or used to control a more complex or automated vacuum protection system.
