Pneumatic Rising Plug Discharge Valve

What's more, it can be used together with the company's floating ball valves. For example, when discharging from a storage tank, the pneumatic discharge valve controls the discharging speed, while the floating ball valve shuts off the upstream medium. The whole set works smoothly, no need to switch between equipment repeatedly.

Let's be clear about the parameters-all are practical data: the nominal diameter ranges from DN25 to DN300, which can handle both small-caliber precise discharging and large-caliber rapid emptying; the working pressure covers PN1.0 to PN6.4MPa, capable of withstanding high-pressure working conditions; it's even more flexible in terms of temperature, operating normally in environments from -40℃ to 400℃, suitable for tasks like discharging high-temperature resin and low-temperature liquids. The material options include cast steel and stainless steel 304/316L, so there's no need to worry about corrosion. The sealing surface is made of PTFE or cemented carbide, basically eliminating material leakage. It fully complies with the national standard GB/T 12237 and can be installed directly on-site without additional size modifications.

Anyone who has used manual discharge valves knows that each discharge requires standing by and twisting for a long time, and it's easy to leak materials all over the floor. Our pneumatic discharge valve avoids these troubles: the pneumatic actuator responds very quickly, opening and closing in just 1-2 seconds, no need for someone to wait around; the valve disc has an anti-clogging design, so even media with particles (such as pigments and powders) won't get stuck, ensuring smooth discharging; it can also be connected to an automatic control system for remote operation, allowing unified management of multiple devices in the workshop, saving a lot of labor. When used with floating ball valves in a reactor system, after the reaction, the pneumatic discharge valve unloads the finished product, and the floating ball valve adds raw materials-unloading and refueling don't interfere with each other, directly improving production efficiency.

Its application scenarios are also wide: it can be used in chemical plants to unload solvents and coatings, in pharmaceutical factories to discharge medicinal powders and liquids, in food factories to drain syrups and sauces, and even in the environmental protection industry to handle sludge. Moreover, our after-sales service is reliable-all pneumatic discharge valves come with a one-year warranty. During the warranty period, whether the seal is damaged or the actuator has problems, as long as it's not caused by human factors, we provide free repairs and replacement parts, no extra cost for you. Whenever you have questions about installation or use, you can contact our technical team at any time-someone is available 24 hours a day to teach you installation via video or help you troubleshoot remotely, no need to figure it out on your own.
