Water is a vital resource and component to human life. From the municipal water system in your city to the bottled water you purchase from your local grocery store, the potable water you consume must conform to a strict set of standards that govern the safety and cleanliness of the final product that is offered and available to customers.This important set of standards, which was developed and is maintained by the NSF Organization and is approved by the American National Standards Institute (ANSI), who oversee the consensus for developing standards in manufacturing and process procedures in the United States, is legally recognized nationally as the regulation for governing the human health effects assessment of drinking water contact materials, components, and devices.

ANSI/NSF Standard 61 standards were developed by the National Sanitation Foundation (NSF), and the American National Standards Institute (ANSI) and relates to water treatment which establishes stringent requirements for the control of equipment that comes in contact with either potable water or products that support the production of potable water.

The KSB Group has further developed and completed its range of gate valves, globe valves and check valves for power plant valves in countries using ANSI/ASME standards.Under the type series names SICCA and ZTS, KSB valves now cover all pressure classes up to ANSI Class 4500.

   Val-Matic has become the first air valve manufacturer to have their complete line of air valves certified to NSF/ANSI 61 for potable water use provided by Underwriters Laboratories (UL) and NSF/ANSI 372 for lead-free products, material and components provided by WQA (Water Quality Association), after completion of testing and data verification.  Legislation in most states requires that drinking water systems must use certified products, if available.

The new Sharktooth provides excellent throttling characteristics, plus aerodynamic noise attenuation, and liquid cavitation reductions. An innovative Control Cartridge is used to turn triple eccentric butterfly valves into control valves with exceptional control characteristics, as well as Class IV, V, or VI metal-to-metal, fire safe shut-off. They are readily available in carbon steel, stainless steel and special alloys for liquids, gasses, and steam at temperatures from cryogenic up to 850F in 150, 300 and 600 ANSI pressure classes, from 3 in through 48 in, with a wide choice of actuators and control accessories.
