The Spartan Scientific Series 4600 2-way, normally open or normally closed, pilot operated diaphragm solenoid valves are offered standard with an adjustable metering handle to restrict or manually shut off media flow. Media and pilot can be separated to extend the life of the valve by keeping corrosive material out of the pilot section. These valves can be controlled by either an internal or external pilot which allows control of pressure range applications from 15 psi to 150 psi. The 4600 is available in ¾” and 1” sizes with a 25 mm orifice, has an ambient temperature range of -10°C to +50°C, and is media compatible with inert gas, water, air and emulsion. In addition, the 4600 has a glass-filled nylon body and cover, nitrile diaphragm, stainless steel internal components, nitrile seals, and a standard copper shading ring. • Orifce Size: 25mm (1.0 inch) • Pressure: Minimum: 15 psi • Media: Inert gas, air, water, emulsion • Mounting: On pipe
