Knife gate valves pass safety standards test

World Coal,

DeZURIK, a valve manufacturer in the industrial and municipal markets, has announced that four knife gate valve product lines have earned Safety Integrity Level (SIL) Certification, as per the requirements of the IEC 61508:2010 standard. The IEC 61508 international standard on Functional Safety assures that safety-related systems provide the necessary risk reduction required to achieve safety for the equipment.

DeZURIK’s KGC Knife Gate Valves, KSV Severe Service Knife Gate Valves and KUL Urethane Knife Gate Valves have been certified as SIL 3 capable; KSV Double Block & Bleed Valves have been certified as SIL 2 capable. The SIL certification means that these valves styles are suitable for use in critical applications up to the SIL rating. The SIL rating reflects the level of risk reduction the device can provide when used as part of a safety instrumented system.

A spokesperson for the company confirmed these valves are suitable for application in the coal industry.

The third party assessment and certification by exida verifies that the product and safety manual, as well as the processes that are used for development, testing, configuration management and quality control comply with the 250+ requirements of the IEC 61508 international standard.

The company said that, by using the latest advancements in technology, such as solid modelling, finite element analysis, 3D rapid prototyping and computational fluid dynamics, DeZURIK engineers create valves that offer superior installed performance in some of the toughest applications in mining.
