The Valtek GS is an environmentally-friendly control valve that 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.

In addition to value and high performance, the Valtek GS accommodates a range of sizes and pressure classes:

  1. General service applications in sizes 0.5" to 6" (DIN 15 to 150)
  2. Pressure class 150 and 300 (PN 16 to 40)
  3. Market leading Cv in a globe control valve package

Boasting quick installation and simple setup by maintenance technicians without instrument or process engineering skills, the Valtek GS high capacity valve is available in multiple trim and material options. The GS handles a wide array of general service application requirements for greater long-term value including excellent flow control, durability and reliability equating to less maintenance over the life of the valve.

The new Logix 420 digital positioner supports the Valtek GS control valve platforms and is designed with the latest technology to support precise and reliable control while allowing fast commissioning with its single, push button calibration. The Logix 420 is a compact, explosion-proof (certification pending) positioner that is able to control small to large valves with high flow rates and direct mounting capabilities which virtually eliminate the need for more expensive mounting options. Additionally, the Logix 420 is designed for use in safety--related applications, per IEC 61508 SIL3 certifications.

"When combined with the Valtek GS, this package provides both maintenance technicians and process plant operators an optimal balance of performance and value without compromise to product quality, safety or integrity," said John Lenander, vice president and general manager, Flowserve Flow Control Division, Oil and Gas Sector.

Among competing globe control valves, the Valtek GS and Logix® 420 fully integrated package can deliver the highest flow capacity - over 55Cv (2-inch valve). Once again, Flowserve proving to lead the market in best application fit, performance and value.
