Haldex brake systems operations trace their roots to 1913, when Axel Diurson patented an invention involving an automatic brake regulator system for railway vehicles. Garphyttan, which dated from the 1920s, Haldex, which dated from the 1960s and Hesselman, which dated back to the 1930s. Brass and steel valves are both capable of higher and lower temperatures than a plastic solenoid valve.The Haldex Group was formed in 1985 through the consolidation of three Swedish vehicle industry subcontractors. The temperature ranges from 15 to 250° F (-10 to 120☌) which is below freezing and above the boiling point of water. Pressure levels will also vary depending on the media flowing through the valve. All ranges are available on the specs of each product page. These levels should be considered before attaching your valves. The pressure range and flow rates vary depending on the size of the valves and power ampages. If you are connecting your valves to an outlet in a house, you would likely need it to be 120VAC. For example, if your power is coming from a car you would likely need a 12VDC valve. What is the power source you plan to connect your valves to? The connections should always match the source. Normally closed would be used if your application requires keeping the media in place and you want to use the valve to open up the flow, such as when installing a sprinkler system. Normally closed solenoid valves will block media from flowing while in the off position and require electricity to open and stay open.Ĭhoose normally open if you need to keep media flowing through and need the valve to shut off the flow. A normally open valve will allow media to run through it consistently until it is energized to close the valve. The two types of solenoid valves are normally open and normally closed. For that application, stainless steel or plastic valves would be the preferred choice. Brass valves are not recommended for drinking water. What type of media do you need to control? Brass valves are excellent for hot water, air, weak acids, weak alkali, Freon, and fuel (gas or diesel).

If you still have any questions or need guidance, feel free to contact us for some assistance. Below are a few important criteria to consider before buying a valve, based on your application and requirements. Some of the benefits of electric solenoid valves with a brass body include:Ībsorbs and withstands heat better than plasticĮasier to seal and/or weld than stainless steel valvesĪs you can see from the catalog above, there is a large selection of brass valves to choose from. Though it is considered a soft metal, brass is a durable material that makes them an optimal valve choice for many applications. If you are looking for a different type of electrically controlled brass valve, please see the below pages:īrass is a somewhat soft metal alloy formed by a combination of copper and zinc. This page is for our brass electric solenoid valves. Brass is the ideal choice for a wide range of applications. These valves are available in both Normally Open and Normally Closed positions.
