Hedaray Fluid Control Systems (Suzhou) Co., Ltd. specializes in infinite circulation volumetric fluid metering solutions. Our screw valve system is based on the infinite piston principle and belongs to volumetric quantitative conveying products. The interaction between the stator and rotor provides assurance for the metering and conveying of materials, which is similar to the principle of an infinitely moving piston. Its unique self sealing function completely prevents medium overflow during shutdown; Suitable for high filling fluids with low to high viscosity, solid particles, wear resistance, and sensitivity to shear forces; Equipped with a suction function to prevent dripping,...
