Media Separated Valves

The Spartan Media Separated Solenoid Valve line uses the high quality Spartan solenoid operator at its heart but adds a very specialized and exacting twist. The Media Separated Valve consists of a convoluted rolling diaphragm, coupled with a specially designed cavity which allows for minimized pressure-force ratios that promote function while ensuring that the metal parts stay clean and dry. All of this plus a very low volume for ease of cleaning and flushing of the valve. Specifically designed for media service, these valves are the heart of machinery used in bun steaming to embryo inoculation. Offered in media compatible materials, Spartan Media Separated Valves solve problem applications in media control.

  • Series 3B23

    The Spartan Scientific Series 3B23 is a compact, media separated 2-way normally closed solenoid valve for use with chemicals or water whereby the media is contained in the valve cavity and does not come into contact with the metal parts of the solenoid operator. The 3B23 features a long life solenoid that incorporates a fully encapsulated coil, stainless steel plunger and tube assembly as well as a rolling diaphragm which enables the valve to function at pressures up to 120 psi with orifice sizes ranging from 0.6mm to 2.0mm. Flow rates of 1.5 gpm can be attained. The single in-line valve body features metal reinforced 1/8"NPT threads and has an ultra small volume and simple flow path for clean switching. The valve is available in all standard voltages and comes standard with a 6.5 watt coil.

  • Series 4B23

    The Spartan Scientific Series 4B23 is a media separated, dry operator type 2-way 2-position solenoid operated valve where the media remains isolated from the metal working components within the valve. This creates a barrier to contamination to both the fluid and the operator which serves two purposes. The media remains untainted by the metals in the operator while the close tolerance moving parts of the valve are insulated from the effects of particulates, aggressive chemicals which can effect long term life of solenoid valves. The 4B23 is available in 1/4 or 3/8 inch NPT connections with orifice ranges from .8 to 5mm which gives the 4B23 great flow and operating pressure ranges to meet differing applications. The 4B23 features a DIN quick connect coil or flying leads connection. The valve is designed for long trouble free life with the incorporation of a rolling type diaphragm, life cycle proven metal operator components and a fully encapsulated coil system. The Valve is available in normally closed or normally open configurations and has two body ports for convenient fluid connection.

  • Series 4BKR

    The Spartan Scientific 4BKR is a 2-way, 2-position media separated solenoid valve that is used for the control of ultra pure or corrosive media that would otherwise cause premature failure on wetted type solenoid valves. Featuring the Spartan Scientific low volume valve cavity and the rolling diaphragm, the 4BKR has no convolutions for chemicals to congregate or dead spots for flow. The all encapsulated coil, stainless tube and plunger assembly are designed for a long trouble free life. Also featuring a quick connect interface, the valve can be mounted in a gang style on a manifold block by using four fasteners and two o-rings. The valve is available in Normally Open and Normally Closed functions, with orifice ranges from 2.4mm to 5.0mm and boasts Cv ranges from .245 to .63.
