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.

The unit installs in a modular form between an existing coil and connector with a plug and play design and retrofits on virtually any installation. The Cycle and On times are easily adjustable on the compact sandwich timer and features two status indicator lights. The Cycle Time drain has settings to release moisture every 1 to 45 minutes. The On Time setting allows you to set how long you want the valve open, 0.25 to 25 seconds. We offer a variety of Nylon or Brass valves depending on your application. These 2-Way, 2-Position, Normally Closed valves range from 1/4”, 3/8”, 1/2” or 1” NPT and can handle pressures up to 230 psi max. The Series CRDV offers its users the most versatile combination of timing and flow capacities in the industry today, and is proudly made in the USA.

The Spartan Scientific Series CRDV/S Condensate Removal Drain Valve keeps your air compressor tank and air lines free of moisture by coupling a state of the art automatic timer with a solenoid valve, reducing rust and clogged air components while increasing compressor cycling and machine life. It features a self-cleaning cycle every 24 hours, status indicator lights, environment resistant design for long cycle life, along with an on board microprocessor from discrete components. As water effluent enters the CRDV/S, the self-learning mode opens the valve more often or less often based on the sensing of the water and demand thereof. The utility, size, ease of installation and price rival the features and cost of conventional timed electric drains.

The Spartan Scientific Stepper 6 stepper valve is a self-contained Media Separated Electronic Proportional Flow Control Valve designed for highly accurate electronically controlled variable flow control of inert fluids and gases. Applying analog input signals to built-in control circuit of the stepper valve, it is possible to produce linear variable flow output. The stepper valve can control its flow by using 1,500 positions through its valve stroke range which can be dialed down to the step, creating reliable and repeatable flow rates from 0 to 6.5 GPM (water) @ 120 PSI.. The valve features a built-in electronic control that accommodates either open or closed loop control by use of electronic signal input of either 4 to 20 mA, 0 to 10 Volt DC. Valve standard operating voltages are 12 or 24 VDC. The Stepper 6 has a separating diaphragm that maintains dry mechanical movement and is designed for long life and high flow. The diaphragm is designed with a specialized convolution and elliptical flow tip producing a linear flow versus valve stroke position. The Stepper 6 valve body is available in 1/8”or 1/4” port sizes with a maximum flow orifice of 6 mm. Featuring multi orientation mounting and the quick connect M12 connector mates to the valve for a sure environmentally resistant enclosure to NEMA4 / IP65. This energy saving valve uses voltage to move into position and needs only 60mA when position is found and maintains a steady state. For fast troubleshooting, the on-board indicator LED (RGB) light ring displays status of the device.
