Request InfoKurt J. Lesker Co.The Throttlemaster vacuum gate valve from Kurt J. Lesker Co. controls a vacuum gate to any position with an accuracy of ±0.002 in. The user positions the gate manually during process development from front-panel controls on the 1/4 DIN electronic chassis. The chassis accepts 0- to 10-V or 4- to 20-mA signals from a PLC or host computer and gives contact closures to indicate open and closed positions. The gate valves come in aluminum or stainless steel constructions with either ANSI or ISO flanges.See full productRelated content from Photonics MediaWEBINARSPhotonics.com 10/27/2021Fiber Optic Solutions for Medical DevicesSteve Allen provides a brief overview and examples of procedures that continue to push adoption and proliferation of optical fiber-based medical devices.
