This is my first time choosing a clamp valve; has anyone who’s experienced this used it before? Give an introduction
Thread Content
This is my first time working on a salt packaging project, with powdered salt as the material involved. The installation location is on the discharge pipeline of the powdered salt silo. The client has temporarily decided to use clamp valves, but there are a few issues I’m not sure about; I hope everyone can offer some guidance: 1. Regarding the selection of materials. The information I found online states that the structure of a clamp valve is relatively simple; it only mentions the materials used for the valve body and the hoses. I’m not sure if there are any other components for which material selection is necessary (Our design drawings usually specify the materials for the valve body, valve core, valve seat, and packing.) 2. Regarding the selection of the actuator. Now that a pneumatic actuator has been chosen, I wonder which type of action mechanism should be selected for it? Piston-type? Film type? 3. Online sources claim that clamp valves cause no pressure loss – is that true? ? I’m still inexperienced; this is my first time using a clamp valve. Thank you all for your guidance. I was wondering if any of the seniors here have relevant materials or samples that they could share with me; I would be extremely grateful
It seems I posted in the wrong forum. Sorry about that

The valve body is usually made of iron or aluminum alloy; there is no need to specify the material of the valve core. This valve is suitable only for low-pressure and normal-temperature environments. Applicable media include slurry with particles, etc. As for the drive type, manual operation is commonly used; electric and pneumatic options are available depending on the specific conditions at the site
That way you’ll understand: some media contain not only strong acids and bases but also a large amount of solids, such as the pulp black liquor used in the paper industry. Ordinary valves are neither resistant to corrosion nor resistant to clogging. A pipe clamp valve can be used here. Simply put, it’s a tube connected to a pipeline; when it needs to be separated, a very strong clip is used to clamp it shut. Loosen this clip when it needs to be opened. Clamp valves cannot be used in very high-pressure environments because they cannot hold tightly. 1. The selection of material must take into account the corrosivity of the process materials, as well as temperature and pressure. 2. The actuator is determined based on control requirements. If it is just about releasing the drain valve, manual operation is common. If it is determined that a pneumatic version will be used, which actuator to choose can be consulted with the instrumentation specialists or professional manufacturers. 3. In principle, it can return to its original state once the clip is released; there is a concept known as memory effect, but excessive switching will eventually cause damage. Clamp valves also need to be repaired. There are some introductions on Baidu Baike, and the basic information is fairly reliable. https://baike.baidu.com/item/Clamp Valve/9471449?fr=aladdin
