330850-90-05 High performance valves feature a variety of design features – mount directly to a variety of actuators to maximize valve flow and provide bubble-level sealing performance in two-way sealing and end-of-pipe applications.
Easy to maintain valves contain seat and packing assemblies and can be serviced or replaced without removing the valve plate and stem.
High performance butterfly valves involve international standards
The design of any high performance valve should meet various international standards and certifications, including:
EU Pressure Equipment Directive 2014/68/EU: establishes safety standards for pressure equipment products (PED) used in Europe.
NAMUR NE 167: The German Board of Measurement and Control Standards330850-90-05 ‘ NE 167 is a technical recommendation published in 2021 that contains the latest best practices for valve pressure and fluid access components, final control elements and field equipment.
EN 593: EU standard for butterfly valves, minimum design requirements for metal butterfly valves in switching, regulating and controlling applications.
EN 12569: Requirements and tests for valves used in petrochemical and chemical production processes.
ISO 15848-1 BH C03: Test standard for leaky valves, ensuring that valves achieve and maintain very low leaky emissions in multiple cycles.
EN 12266-1 Leakage rate Class A: Provide test procedures to confirm that the valve provides zero leakage/bubble level tight shut-off.
High performance butterfly valves provide an economical solution for switching applications330850-90-05 in the chemical and petrochemical industries – with a smaller footprint than other valve designs, improvements in valve seal, stem packing and body design, modern high performance butterfly valves have a long service life and achieve and maintain tight closure of the bubble level and near zero loose emissions.
When evaluating the selection of valves for a project, it is important to discuss with the valve supplier and carefully examine the design characteristics and selection of various alternatives. Low-cost options may be available, but a better valve design will provide superior performance over a longer service life, with a more cost-effective total cost of ownership throughout the life cycle.
