Based on more than 60 years experience Controlled compression of seat seal in valve production SPX has developed the The metallic stop ensures defined compression of the seat seal, DELTA SW4 hygienic single seat valve: a reducing material stress. Production downtime can by minimized. modern, highly versatile single seat valve, Furthermore, this arrangement ensures smooth product transition which does not only fulfil the demands of in this area. Wear resistant elastomer/PTFE shaft seal and shaft today’s process industry but also a great bearing arrangement increases seal lifetime and consequently minimises maintenance costs and general downtime. Installing the DELTA SW4 valves is an Installation and maintenance convenience investment in efficiency, production flexibility or in other words: in the future. When designing this valve great emphasis has been put on facilitating valve handling, installation and maintenance. Characteristics Its hygienic design makes it ideal for applications in the dairy, • A handy clamp closure system or a few bolts (DN125-150 and 6”) between housing and yoke provides quick and easy access to product-wetted parts. The housings (DN25-100 and 1” 4”) may be orientated in various directions to ensure multiple installation possibilities. • Moulded elastomer profile seals with clear identification markings ensure prompt and failsafe identification of seals during maintenance. • Only one hexagonal nut outside the product area ensures quick and easy service of the valve. pharmaceutical industries. • Different actuator sizes are available, and for DN40-100 and 1½” - 4” these are interchangeable. This means that different holding pressures can be handled. The valve is EHEDG tested and it is available in on/off and • Actuator design prepared for NC/NO (Normally closed / normally open). change-over versions. The valve can also be supplied in 3A • Despite the thick-walled housing the valve is very low weight. approved design. • Maintenance-free actuator, covered by our 5-year guarantee. beverage and brewing industries, as well as the chemical and Features & benefits Sturdy ball shaped housing designed for optimum cleanability. The extra wall thickness of the valve housing minimises stresses in the seat area. At the same time the ball shaped housing effectively prevents sump or dome, making CIP-cleaning more efficient and more reliable. A comprehensive range of valve housings are

Control Units Technical data The DELTA SW4 valves can be delivered with a comprehensive range of DELTA CU control units. The DELTA CU are electrically provided to connect direct to a PLC system (DELTA CU Direct connect). Optional to support fieldbus protocols like AS-i, Profibus E PDM, H N B R, FPM and VMQ: 1 3 5 ° C / 27 5 ° F (Short term: 140°c/284°F) VMQ and FPM should not be used with hot water/steam Options for DELTA SW4 In order to handle every inquiry the following options are available: • Stroke limitator (DN25-100 and 1” - 4”) For fractional sizes, see DELTA SWmini4 data sheet. • Crank...
