Heated Bellows-sealed Isolation Valves
MKS Jalapeño heated vacuum valves are specifically designed to withstand high internal temperatures, limiting contaminant buildup and reduce system maintenance. The standard heater for the Jalapeño 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 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. The legacy lines of MKS Jalapeño valves are available for customers requiring configurations not available as a LoPro™ Jalapeño product.
