The Deltaflux slam shut valve is an ideal solution for all fluid control applications where high differential pressure or great flow rates are involved.
The refined design of the rotating trim allows offering simultaneously high flow rate coefficients Cv and minimum pressure drops in fully open positions, thus creating a unique combination of capacity and rangeability.
Thanks to the versatility and the available range of this slam shut valve, Deltaflux is the ideal solution for all special applications, as well as for use at high and low temperatures, and in aggressive enviroments. Considering its features, Deltaflux is the ideal primary element for ESD (Emergency Shut Down Valve) and HIPPS (High Integrity Pipeline Protection System) systems.
Fields of application:
• Natural gas industry;
• Energy;
• Petrolchemical industry;
• Water transport.
Deltaflux control valves are equipped with special regulating trims making it suitable for applications involving gases or liquids. Moreover, the trim is studied in order to hinder the formation of dirt deposits inside the same.
The trim configuration and the special geometries of Deltaflux allow attaining a high rangeability; moreover, they avoid over pressure within the valve body, thus obtaining a high noise reduction and a longer life-cycle of the sealing parts.
Deltaflux valves are a “Bolted body” project, thus they are easily maintainable. Sealing parts are interchangeable: Moreover, assembling of any kind of controls and accessories is quite easy.
Deltaflux valves, in their standard version, have been developed for a design temperature ranging from -29°C and + 121°C and for a storage temperature ranging from - 40 and + 60°C.
Deltaflux control valves are available up to a 24” diameter, thus allowing regulating also great fluid flow rates.
The control loop is 6-30 psig: other signals available on application
