Valve design examples of development tasks SPeCialized ValVe SOluTiOnS With thirty years' experience in the production and sale of a comprehensive programme of valves, EV Metalværk is now a customer-oriented company skilled in the development of specialized valves. Our clear objective is to be recognized as being the natural place to turn to whenever a need arises for customized valve solutions. CuSTOmized ValVeS In close partnership with customers, EV has enjoyed considerable success in designing specialist valves based on our standard range of valves. Just slight changes to our standard EV and HydroBall( ) valves often result in improved technical performance and cost-saving customized solutions. Sanitary double valve with actuator operation and switch: All parts in contact with the medium are engineered in FDA approved materials. Housing material: AISI 316L Dimensions: 1/2", Ø50, L:142 mm SPeCially designed ValVe SOlu- TiOnS TO CuSTOmer requirements Our R&D department is often asked to suggest new valve designs on the basis of customer requirement specifications regarding material, seals, opening pressure and flow characteristics. In some cases the design is based on our standard EV and HydroBall( ) valves while in others the valves are designed from scratch. Three-way seat valve: Housing material: AISI 316L Engineered with pistons and seat seals of plastic. Long-term tests have shown more than 750,000 operations without failure. Safety valve for ammonia (nh 3 ): Designed for laser welding. Material: AISI304, sinter metal Pressure: Up to 8 bar Temperature: -40 to +100 C Dimension: Ø12 x 5mm Seat seal: Vulcanized in cone Cone and top: Glas-reinforced PPA
Valve design examples of development tasks SPeCially designed ValVe SOluTiOnS TO CuSTOmer requirements -Food industry -Chemical industry -Medico -Cleantech -Paper industry -Oil industry -Pumps -Refrigeration plant -Cleaning systems -Engines and others Safety valve with threaded aluminium splash cap, for ammonia: material: Copper-free, anodised aluminium. Precise action, remains tight up to opening pressure. Seal: O-ring and X-ring. dimensions: NV22, L: 30 mm incl. cap ValVe design Our specialized valves are designed to perform perfectly with the characteristics specified as being essential for trouble free operation of a technical process or flow system. Space considerations often determine the need for a specially designed valve as a valve which has been developed to fulfill a specific task can be made very compact. (Above is shown a plast valve with the dimensions 34x34 mm) Check valve in aisi 316l: Pressure range up to 40 bar for use in applications where particularly strong pressure surges may occur. Special requirements on nominal dimensions. dimensions: 11/2, Ø55, L: 35 mm materials -Brass -Steel -Stainless steel -Acid-resistant steel -Titanium -Aluminium Special alloys available on request. dimensions: 1/8" - 2" angle safety valve with cap, for liquid: Designed using parts from other standard EV valves, thus eliminating the cost of new moulds and machine tools. Opening pressure: 5 bar material: Brass dimensions: 27x45 mm incl. cap
Valve design examples of development tasks drawings Valves have been designed for use in many applications, including: Drawings are prepared in 2D and 3D CAD. 3d drawings can be produced in: STEP, Iges, SolidWorks and STL format. Safety valve in aluminium Pressure: 0.25 bar materials: Housing, ball and spring in seawater resistant, anodised aluminium. dimensions: NV27, h: 18.5 mm EV has great experience with fitting and testing advanced valves for both high and low pressure. A dialogue with the customer is the basis for a genuine development agreement and agreement of production of proto types for testing in our lab. Then the valves are tested at the customer s facilities before the actual production is started. Three-way valve for manual or actuator operation: Pressure: 160 bar Housing, ball and seals in two different titanium alloys (Grades III & IV). dimensions: 1/2", Ø65, h: 47 mm Valve certification/classification: EV has considerable experience in meeting regulations concerning CE marking and the certification/classification of valves. drain valve in aluminium: Engineered in seawater resistant, anodised aluminium for use in maritime environments. Dimensions: NV16, h: 30.5 mm
