The material used for contact with the liquid should be free of copper and zinc, and PTFE is preferred for soft sealing. The actuation time should be within 1 second, and the weight should be less than 0.8 kilograms. The angle of the pipeline where it is installed can vary, and a constant differential pressure cannot be ensured for the solenoid valve; therefore, start-up at 0 pressure is required. It is to be used in Zone 1 areas with explosion hazards. I’m looking for recommendations on suitable manufacturers that can supply solenoids meeting the requirements.
Based on your operational requirements, the following solenoid valves are recommended: 1. Siemens SIPART PS2 solenoid valve: Suitable for media including methanol; it can complete its stroke within 30 ms, weighs 1.9 kg, and features capabilities such as angle adjustment and explosion protection. This product is flexible and easy to use, and can be calibrated and configured as needed. 2. Emerson ASCO solenoid valves: These solenoid valves are of the direct-acting type, with a minimum diameter of DN20, thus meeting your requirements. It features precision and reliability, as well as a compact design, and also meets your requirements regarding explosion protection and the types of media it can handle. 3. VOCOFLAM solenoid valve: This is a solenoid valve designed specifically for flammable media. It can complete its journey in less than 30 ms, weighs about 2 kg, and can adapt to pipes at different angles. In addition, it also features corrosion resistance and high reliability. The specific choice can be evaluated based on actual circumstances. .
The last edit to this post was made by lxazy on 2023-4-10 at 11:13, with additional information regarding the application scenario: the valve and pipeline are installed vertically, but since the pipeline rotates, the valve’s angle changes from 180 degrees of rotation to 17 degrees. The required response time is within 1 second – are there any valves that meet these requirements?
If you need more assistance and recommendations, you can provide more detailed requirements and information, such as the type of equipment that requires solenoid valves and its purpose, the operating temperature environment, the medium pressure, etc. This will help us give you more accurate recommendations. Additionally, you can also contact some solenoid valve manufacturers or professional sales staff to ask for their advice and opinions. .
Thank you; ASCO doesn’t seem to work. Do you have the contact information for the other two?
