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.

Air Piloted Solenoid Valves

Spartan Air piloted valves are offered in sizes from 1/4″ to 2″ NPT and control media and steam from 1 to 750 psi in various valve configurations. These rugged process valves are used in rigorous environments where precise control of media is required. All versions incorporate a long life air actuator which provides the control of piston and ball valve type valves. Materials include brass, bronze, and stainless steel. These valves are media separated by means of the pneumatic actuators as valve operators.

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.

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. Spartan's new closed loop control, The CRDV/S takes away the guesswork involved in the setting of the time ranges for condensate removal. The CRDV/S uses the same time proven large orifice valve but couples a solid state sensor that is imperious to the nasty environment found at the outlet of compressors. The sensor senses the presence of the condensate and opens the valve if and only if condensate is present. In this way, the CRDV/S opens only when needed. This reduces compressor cycling in two ways, it ensures that the tank is always empty of condensate allowing for maximized compressed air volumes and the CRDV/s does not waste air by not triggering when there is no condensate. Made from engineered polymers or brass, the CRDV/s features a full flow 1/2″ orifice as well as a proven solenoid operator design. Both CRDV products are made of the highest quality materials that promote long trouble free life.
