Houston, Texas, USA, XX January 2019Oxford Flow, the pressure control equipment specialist for the municipal water, natural gas distribution and industrial process industries, announces today that it has been awarded the NSF/ANSI 61 and 372 accreditation for its polymer water pressure regulating valve (PRV) range.

Developed by NSF International, a global public health and environmental organization, and the American National Standards Institute, the NSF/ANSI 61 and 372 certification sets standards for the health effects of drinking water system components. This includes equipment such as mechanical devices, valves, process media and pipes. The accreditation – required by 48 US states and 11 Canadian territories – provides municipalities and water utilities globally with assurance that components will not leak harmful contaminants, such as lead, into the distribution network.

The comprehensive certification process saw Oxford Flow undergo a number of steps including product formulation and toxicology information, plant audits and samples as well as laboratory testing.

David Smith, Oxford Flow’s Director of Business Development for North America, said: “By gaining this certification, it really will help to open doors for Oxford Flow as we expand our presence in the United States, Mexico and Canada. Our team has put in considerable effort to get us to this point and, by combining this certification with our industry-leading PRV technology, we believe we have one of the most unique and innovative PRV technologies available to the municipal water services industry.” 

Already in extensive use in the UK and Mexican utilities sectors, Oxford Flow’s polymer water PRVs are constructed from Acetal, a highly engineered thermoplastic, weighing a fraction of the weight of conventional cast iron valves while elevating performance, ease of installation and reliability. The innovative design also eliminates the need for a rubber diaphragm – removing the source of most water distribution PRV leaks.

Following the accreditation, Oxford Flow will now enter into a series of field trials with more than 10 different municipalities across the United States to be conducted in Q1 2019. The company will also continue its efforts to develop a network of distribution partners to support its regional sales efforts.
