Jalapeño LoPro™ Heated Bellows Vacuum Isolation Valves
Overview
Jalapeño LoPro™ Heated Bellows Vacuum Isolation Valves are specifically designed to withstand internal temperatures as high as 190°C to limit contaminant buildup and reduce system maintenance. The standard heater for the Jalapeño LoPro valve is 170°C. The Jalapeño LoPro valve uses up to four heat zones, virtually eliminating any potential for hot and cold spots. The Jalapeño LoPro valve has a smaller profile and is lighter, lower in cost, and easier to maintain than similar competitive valves. With its small footprint, this valve fits as easily into existing vacuum systems as it does into new systems.
- NW25 - NW50
- Uniform heating reduces byproduct buildup to maintain throughput
- 1,000,000 cycle rating (clean environments)
