ZRF Series Square Port Rotary Valve

ZRF Series Square Port Rotary Valve is an important equipment widely used in industrial material conveying systems. It is mainly used for quantitative feeding of powdered, granular or small-piece materials and air locking in pneumatic conveying systems. Compared with traditional round-mouth rotary valves, the inlet and outlet of the square-mouth rotary valve are rectangular or square structures, which can better match square hoppers, silos or conveying equipment, and improve the coordination and sealing performance of the overall installation.
The square-mouth rotary valve consists of a housing, a rotor (impeller), an end cover, a sealing device, a transmission system and other parts. Its inlet and outlet are designed as a square flange structure, which is particularly suitable for working conditions where the upper end is connected to a square silo or a discharge port. The rotor usually has multiple blades and rotates under the drive of a motor or pneumatic device to achieve continuous and uniform material conveying. The interior of the equipment can be made of different materials according to the characteristics of the material, such as cast iron, stainless steel, carbon steel, etc.
The square-mouth structure can perfectly connect the inlet and outlet of square equipment, reduce powder leakage and air leakage, and the sealing components are resistant to high temperature and corrosion, extending the life of the equipment.
Diverse materials, strong adaptability
According to different material characteristics and industry requirements, food-grade stainless steel, wear-resistant lining or anti-corrosion materials can be selected to meet diverse application environments.
Easy maintenance, reliable operation
Reasonable internal structure design, easy disassembly and cleaning of the rotor, simple maintenance, suitable for food and pharmaceutical industries that require frequent cleaning.

An anti-interference and anti-clogging rotary valve

Rotary valves are specialized equipment used in powder conveying systems for unloading, metering, dust removal, quantitative conveying, mixing, and packaging. They are widely applied in various industries such as chemical, environmental protection, petroleum, metallurgy, refractory materials, power, cement, plastics, food, and pharmaceuticals. A common defect of conventional rotary sealing valves is that when a large amount of material enters the valve body, it can become blocked in the material chamber of the rotor, leading to the blockage of the entire rotary sealing valve and damaging a significant amount of material. Therefore, an anti-jamming structure is generally installed at the inlet of the rotary sealing valve. In the existing "anti-interference mechanism for rotary valve material conveying", two pairs of upper and lower feeding baffles are installed, which restrict and guide the material through them. However, when the rotor rotates, the material falls from the lower feeding baffle. If the baffle in the rotor chamber is just below the material at this time, the material will collide with the baffle, causing damage to the material. Additionally, for particles with high elasticity, the material may be ejected in various directions due to the collision. Therefore, it is necessary to design an anti-interference and anti-jamming rotary valve to solve the above technical problems.
