MKS High Flow Valves (HFVs) increase system uptime due to their high cycle count lifetime of 1,000,000 cycles in clean environments and high conductance which allows for faster system pumping. An edge welded stainless steel bellows prevents outgassing and virtual leaks. The bellows stroke length is optimized to assure maximum conductance. The HFVs are designed to be easily and completely disassembled in the field, lowering the cost of replacing parts.
The following options are available for HFV High Flow Vacuum Isolation Valves

HFVs are available with MKS heater solutions which ensure uniform internal temperature profiles to minimize condensation of process gases. An Ultem insulating barrier between the Festo™ actuator and valve body keeps heat inside the valve and away from the actuator. To accommodate process needs for high temperature or chemical resistance, a variety of elastomer seals are offered, including, Viton®, Chemraz®, and Kalrez®. Like all MKS isolation valves the HFV is offered with air solenoids for pneumatic actuation and limit switches for remote indication of the valve’s position.
