Heated, Low-profile, Bellows-sealed Isolation Valves
MKS Jalapeño LoPro™ heated vacuum valves are specifically designed to withstand high internal temperatures, limiting contaminant buildup and reduce system maintenance. The standard heater for the Jalapeño LoPro™ valve is set to 170°C to achieve a nominal interior temperature of 150°C, but other temperature ranges are optional. From room temperature, the heaters typically reach their set temperature in less than 30 minutes and can be daisy-chained with integral locking connectors. The heaters are wired in parallel and are independently controlled. Jalapeño LoPro™ valves use up to four heat zones, reducing any potential for hot and cold spots. Since each heater is designed to uniformly heat a component, there is no need for costly controllers or thermocouples with messy wires.
