Flowserve receives certification of Valtek Mark Series

The SIL certification is a measurement of the effectiveness of a safety system and extends to valves and actuators built in the Flowserve Springville, Utah, and Bangalore, India, facilities. To obtain SIL 3, Flowserve partnered with exida to certify the product reliability, design and engineering processes for the Flowserve Valtek Series controls as SIL 3 capable per International Electrotechnical Commission (IEC) 61508.

Flowserve Valtek Mark Series control valves offer high performance in liquid and gaseous services, while allowing easy, fast and inexpensive maintenance. The spring-cylinder-actuated valves provide high-positioning accuracy, repeatability, controlled high speed, reliable response and tight shutoff. A self-aligning seat ring enhances the shutoff capability of the Mark Series valve. Additionally, due to the Mark Series valve’s high degree of parts interchangeability, fewer inventory parts are required. The valve actuators are capable of handling up to 150 psig (10.3 barg) supply air and have the thrust to shut off against high-fluid pressures.

Eric Anthony, marketing product manager, controls, Flowserve Flow Control Division, said: “Flowserve Valtek Mark Series valves and actuators are among the safest, most reliable flow control products on the market. SIL 3 certification gives enables our customers to have increased confidence in the performance of Flowserve Valtek products.”
