Tameson has a large selection of 2/2-way cast iron solenoid valves, which have 2 ports (1 inlet and 1 outlet) and 2 switching states (open or closed) that are electromechanically controlled. They are used to solely start/stop the flow of the media and are most commonly normally closed (power to open), so that if power fails the valve will close. They can also be designed as normally open (power to close) or bi-stable (latching). There is a wide array of selection criteria from orifice size, connection type, voltage, pressure range, operation, design, certification, seal material, and housing material to ensure you have the correct valve for your application. We have port sizes between 1/8” to 2” to cover the majority of applications, but for applications outside of this we also have you covered. AC or DC voltage coils are available depending on the electrical wiring available in the application. View our pressure ranges along with different solenoid valve operation types (direct, semi-direct, or indirect), as this will affect if you need a pressure differential for complete valve opening. If needed, we also have different versions, for example, medium separated, ATEX certified, or oil and fat free to meet your application requirements. The valve’s housing and sealing material will ultimately affect the type of media that can flow through the valve, but it is typically either gases or clean liquids. Please note that the internal parts of the solenoid valve are made of different materials (usually stainless steel 430F for the plunger). Medium separated valves separate these parts from the fluid. A solenoid valve is often selected due to good sealing properties, fast response time of typically between tenths to hundreds of milliseconds, durability, reliability, and a wide range of operation types and materials to find the right one for your application. The cast iron housing allows for neutral media and is often used for larger installations. View our chemical resistance chart to ensure that your housing and seal material are suitable for your media.
