Flowserve Corp. recently introduced the Valtek GS globe control valve and Logix 420 digital positioner. These products provide a fully integrated valve package for general service continuous process control throughout the plant.
The Valtek GS complies with the latest standards for controlling fugitive emissions requirements (ISO 15848). The GS is based upon simple, yet proven Valtek design philosophies of building an instrumented control valve package by providing automated calibration and some of the highest flow rates in a general service globe valve package - over 55 Cv in a 2-inch valve and nearly 150 Cv in the 3-inch model.
The Valtek GS is available in multiple trim and material options. It handles a wide array of general service application requirements.
The new Logix 420 digital positioner supports the Valtek GS control valve platforms. It’s a compact, explosion-proof (certification pending) positioner that is able to control small to large valves with high flow rates and direct mounting capabilities. Additionally, the Logix 420 was designed for use in safety--related applications, per IEC 61508 SIL3 certifications.
Both the Valtek GS and the Logix 420 products are included in the latest release of Performance -- the Flowserve Control Valve sizing, selection, and project management software. Performance employs industry-standard IEC and ISA sizing equations, among other measures, to assist the user in selecting the best solution for their application.
