Spartan Scientific was formed in 1978 with a mission to redefine industrial solenoid valves and related products. We started with DIN quick connect solenoid coils, quick mounting solenoid operators and interchangeable coil versions. Spartan has effectively reduced installation costs and related setup while reducing retrofits and service times. Spartan solenoid valves incorporate fully encapsulated coils and the highest quality brass and stainless steel in every assembly. Our solenoid operators can be placed directly into your assembly for a neater, more compact end product which meets functional as well as aesthetic demands. Many of the products manufactured by Spartan Scientific are specials, or variations of standard products.


Solenoid Operators

Solenoid Operators

At the heart of each valve made by Spartan Scientific is the solenoid, plunger and plunger tube. While seemingly simple devices, the key to long, trouble free life is in the details of these operators. Made with premium materials to exacting standards and checked by state of the art measuring devices, the Spartan solenoid offers the best value for function on the market today. A guarantee of high cycle life as well as rugged and trouble free life of the valve is Spartan's quality goal. More than just conversion of electrical signals into fluid mechanical motion, the Spartan solenoid is the culmination of many years of experience and knowledge of media control.

Media Separated Valves

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.

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.

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.

Drain Valves

Drain Valves

Spartan Scientific CRDV (condensation removal drain valve) are unique and efficient methods to increase efficiency of industrial pneumatic systems while ensuring that the system remains free of condensate and contaminates. The CRDV consists of two main types of operations, open and closed loop. Open loop drains consist of timers attached to diaphragm type solenoid valves which are operator set to energize in preset time intervals in order to remove condensate from the pneumatic system. While these systems are low cost, by nature they can become somewhat inefficient as the volumes of condensate are constantly changing throughout the year necessitating changes to the timing of the removal of condensate.



The Model CRDV (Condensation Removal Drain Valve) is a compact, modular combination specifically designed for air line condensation removal. With two timer / connection options and three valve sizes to choose from, an optimal system can be attained for most condensation problems.



The Spartan Scientific CRDV/S is an electronic on-demand drain which couples an electronic sensor integrated with a solid-state logic analysis circuit to determine the exact amount of time the modular solenoid valve should be energized to empty condensate from the pneumatic system.
