Design:
To meet the customer requirements in flow control systems, Value Valve is constantly developing our products to be a superior product choice in sever applications. Value Valve created a new unique design for a Double Offset Butterfly Valve by improving the materials as well as the mounting structure.
Value Valve is one of the few companies that has been certified with the Safety Integrity Level 3 according to IEC 61508-1 and ISO 9001 by TUV for the VF-9 series.
Why SELECT SIL-3 Valves/ Actuators?
SIL stands for Safety Integrity Level. A SIL is a measure of safety system performance, in terms of probability of failure on demand (PFD). . There are four discrete integrity levels associated with SIL: SIL 1, SIL 2, SIL 3, and SIL 4. The higher the SIL level, the higher the associated safety level, and the lower probability that a system will fail to perform properly. For the process industries, SIL 4 systems are so complex and costly that they are not economically beneficial to implement.
Selecting the appropriate SIL level must be done carefully. Costs can increase considerably to achieve higher SIL levels. Typically, in the process industry, companies accept a SIL 2 rating, but if you can obtain a Butterfly Valve or Automated Butterfly Valve Package with a complete Standard SIL-3 rating, utilizing our RP series actuator with little or no increase in cost, then that is the logical decision.
