Top-opening Discharge Valve

Whether it's viscous materials, granular materials, or ordinary liquids, it can control and discharge them stably and completely. Moreover, it can be used together with the company's floating ball valves. For example, in a complete reactor system, the top-mounted discharge valve is responsible for precise bottom discharge, while the floating ball valve regulates the feed flow. The inlet and outlet cooperate perfectly, eliminating the need to mix parts from different brands and saving a lot of trouble.

 

If you care about specific parameters, let's be straightforward: the nominal diameter ranges from DN25 to DN300, covering both small-batch precise discharge and large-batch material unloading; the design pressure reaches PN1.0-PN6.4MPa, which can withstand high-pressure working conditions; the applicable temperature range is wide, and it can work normally in environments from -40℃ to 400℃, even in scenarios like steam-heated reactors. Materials can be 304 or 316L stainless steel, so there's no need to worry about corrosion. The sealing surface is made of polytetrafluoroethylene or cemented carbide, basically avoiding material leakage and jamming. It fully complies with national standards such as GB/T 12237 and can be directly connected to flanges during installation without additional size modifications.

Friends who have used discharge valves know that traditional valves either fail to discharge completely with much residue, or are difficult to open/close and troublesome to maintain. This top-mounted discharge valve is specifically designed to solve these problems: it adopts a top-mounted structure, and when the valve core opens upward, it can completely separate from the material outlet, ensuring extremely clean discharge. The residue is 80% lower than the industry average, and it's also easy to clean, making it especially suitable for industries like pharmaceuticals and food that have high hygiene requirements. Additionally, the sealing surface of the valve core has been reinforced, so even if the medium contains a small amount of particles, it's not easy to wear, and its service life is more than twice that of ordinary discharge valves. Three driving methods-manual, electric, and pneumatic-are available, making it convenient for workshop workers to operate. The electric version also supports remote control, eliminating the need for personnel to stay beside high-temperature and high-pressure equipment.

As for application scenarios, the range is even wider. It can be used for reactor discharge in chemical plants, raw material feeding in pharmaceutical workshops, syrup transportation in food factories, and slurry discharge in coating factories. For instance, in a pesticide production workshop, the 316L stainless steel top-mounted discharge valve is used for unloading corrosive raw materials, and it is paired with a floating ball valve to control solvent feeding, making the entire system stable and safe. In food processing plants, the 304 stainless steel material meets hygiene standards, ensuring no residue during discharge and preventing raw material contamination.
