The Spartan Scientific Series 3505 is a 2-Way, 2-Position, internally piloted solenoid valve for the control of air, emulsion, inert gases and water. The valve features an all brass body and a full flow 1/2” orifice while maintaining a 1.5 minimum pressure differential. The design allows for a tight seal on the orifice at 0 psi. Available in 1/4”, 3/8” and 1/2” NPT, the 3505 can handle pressures to 230 psi. The encapsulated coil construction ensures that the valve functions well under long periods of activation (100% duty), as well as providing a high degree of environmental protection (NEMA 4). The inner valve functions as a direct assist using a flat diaphragm and orifice plate. Pressure differentials shift the valve to full open or full closed. A push, non-locking manual override is standard.

The Spartan Scientific Series 35KR 2-Way, 2-Position solenoid valve is a variation on the popular Series 3500 valves which feature miniaturized size vs. flow rate while allowing the user to manifold multiple outlets with one inlet. The 35KR design features the direct pilot design which controls 0 to 150 PSI in the all plastic version. The intermediate orifice plate design is the key to the 35KR in that it includes all the details of careful orifice design and creates a simple sealing pattern which can be mounted to integrated equipment and complex manifolds with simple mounting screws. The mounting style reduces leak points and numbers of connections. The 12mm orifice promotes full flow while the valve body, at only 1.5 inches wide, can be gang mounted to give impressively small envelope packages with many outputs. The simple mounting pattern is shown under dimensional data and can be machined into many varied manifold configurations.
