For GEMÜ R480, R481, R487 and R488 Victoria butterfly valves for drinking water applications, it is possible to select between the American NSF approval with the special function “N” and the European DVGW approval with the special function “D”.
The NSF/ANSI/CAN 61 certification is also valid for all products that can be supplied with liner code W in combination with stainless steel disc code A, B and D.
The DVGW certification is valid for all products with liner code W in combination with stainless steel disc code A, B and D and special function “D”.
The composition of the seal in the GEMÜ 480 and GEMÜ R480 has been tested in accordance with the old Elastomer Guideline and the new KTW-BWGL standard. Following the publishing of the third change to the KTW-BWGL in March 2022, a transitional period is in place lasting until March 2025. After this point, the old Elastomer Guideline will be withdrawn.
With the GEMÜ R480 Victoria series, GEMÜ is able to provide its customers with security when planning future projects that will last beyond the specified transitional period and can supply suitable butterfly valves in the long-term.
