Precise flow control. Tight shutoff – all in a single unit: XACTROL® severe service control valves are accurately engineered for applications where minimum flow and relatively high differential pressures are required. They give you an “exact” flow control solution every time, from minimum or normal control to full rangeability across a wide range of pressure drops and conditions. Because your application is so important, every XACTROL solution is calibrated and tested in the state-of-the-art ValvTechnologies Flow Test Loop – so you get critical accuracy. Key Benefits * Superior failure resistance, reliability through wave-spring sealing * Constant packing load maintained with four-stud, live-loaded packing assembly * Fast block-and-bleed thanks to two-seat design * Real flexibility in application, from 2 to 42 inches * Through-bonnet, single-seal top-entry design improves maintainability and repairability
