Tulsa, Oklahoma-based OCV Control Valves, manufacturer of automatic control valves, recently announced that it now has the most comprehensive NSF/ANSI 61-G listing in the control valve industry, certified through NSF International. OCV’s control valve product line maintains its previous NSF/ANSI372 listing for all control valves in addition to adding the NSF/ANSI 61-G listing for virtually all models in sizes 4 to 24 inches.
Products certified to NSF/ANSI 372 meet the required lead content requirements, while products certified to NSF/ANSI 61 also pass a leachable test to evaluate all contaminants of health effect concern, not just lead. OCV’s NSF/ANSI 61-G listing not only applies to pressure reducing and pressure relief valves, but valves used in many other applications including, but not limited to, electronic control, check valves, surge anticipation valves, solenoid valves, rate of flow control valves, altitude control valves, and float control valves.
