Double rotor metering valve
The double rotor metering valve is composed of two rotors. The large rotor is used for rough measurement and the small rotor is used for accurate measurement. The operation and use of the valve must be matched with the batching and weighing system. The clamp type assembly mode is convenient for users to disassemble and assemble quickly. This valve is mainly used for packing and metering of material and granular materials.
