Water Valves - Large Flow Solenoid Valves

½" to 2" solenoid valves are often used to shut off or open a flow in water pipes. There is a minimum pressure in domestic water pipes so that the servo-controlled solenoid valves can be used here without any problems. However, if you want to control the flow of a tank, the solenoid valve only must deal with the hydrostatic pressure, which is often well below 0.3 bar. In this case, we recommend the servo- controlled valves, which also work without minimum pressure and are available up to 1".

Brass solenoid valves, which are designed for large flow rates, are used in many areas of industry, in building services, especially sanitary technology, and for irrigation. Our large warehouse offers you an extensive selection. The short delivery time is particularly favorable if you need the components immediately. In this category you will find 2/2-way solenoid valves made of brass or stainless steel. The designation of the way means that the valve has two pipe connections and that the two switching positions "open" and "closed" are possible. With solenoid valves, an electrical signal activates a solenoid, causing the valve to open or close. These valves can be controlled quickly. They are suitable for both liquid and gaseous media. Their task is to stop or release the flow of the medium. They are not suitable as safety valves. These solenoid valves are mainly made of brass, with stainless steel used for the armature guide systems and the valve seats. Brass and stainless steel are very resistant. Various materials are available for the seals. The appropriate sealing material depends on the area of application. For example, NBR is suitable for air, water and oils with a temperature between -10 and +90 °C. EPDM is mainly used for hot water and steam. It also withstands weak acids and bases with a temperature between -10 and +120 °C, but not fatty media. FKM withstands temperatures from -10 to +130 °C and is mainly used for hot water and hydrocarbons.

Switch position and connection sizes

You will see the additions NC or NO in the product descriptions and the filter function for the search. This will tell you if the valve is open or closed when there is no power. NC stands for "normally closed", which means it is normally closed. Normally open NO stands for "normally open". Energizing the solenoid with power causes NO valves to close and NC valves to open. In addition, there are valves that are bistable. There is no fixed rest position for these. They receive two different control signals and always remain in the last switched position. When choosing the valve, the connection size is also important. You can therefore use the filter function when searching for a product and display all valves with a specific thread size. This is a cylindrical Whitworth pipe thread for non-thread sealing connections according to ISO 228-1. The inches in the descriptions do not match the actual inside or outside diameter. This is because the inch measurement originally referred to the inside diameter. However, this became larger and larger over time due to the use of thinner materials, while the outer diameter was retained for reasons of compatibility. If in doubt, use the relevant tables to determine the correct connection thread. As a first orientation, you can see the diameter of the hole in millimeters next to the thread designation:
