Flowworld DV80 series piston CNC valve is a high-stability regulating control valve designed by FLOWWORLD TECHNOLOGIES LTD. of Canada and widely used in the field of fluid control. The mechanical structure design of this CNC valve is simple and reasonable. The valve opens and closes independently, and the liquid flow resistance is small. It can be suitable for the control of self-pressure (self-flow) and various high-viscosity liquids (including diesel wax). This CNC valve has been widely used and has achieved good results in applications such as flow regulation control, quantitative loading, ethanol and gasoline proportioning, and quantitative loading relying on self-pressure (self-flow). It has become an ideal replacement product for electro-hydraulic valves for loading. Features: u Actively controls the opening and closing of the piston through the motor, with few mechanical transmission parts, easy maintenance, and a service life of more than 100,000 times ； u The numerically controlled valve opening is linearly adjusted, which can achieve precise control of liquid flow, and the accuracy is within ±1L. ； u The working process of the CNC valve is less affected by the viscosity and pressure of the liquid, and the working process has low noise and small temperature rise. ； u The shell, piston, cylinder liner, etc. of the CNC valve are all made of stainless steel, and the sealing ring is made of special materials that are resistant to acids, alkalis, and various chemical solvents. ； u After power outage, the valve can quickly and automatically close ； u Can be installed horizontally, vertically, or tilted, and has a wide range of applications ； u The opening and closing speed is adjustable, which is more conducive to eliminating "water hammer". Product advantages: u The valve is automatically opened and closed by the motor, and is not affected by the liquid pressure in the pipeline and the liquid level in the oil tank. ； u The motor that controls the opening and closing of the valve runs smoothly without causing water hammer. ； u The valves are all made of stainless steel, and no anti-corrosion treatment is required on site, making them more suitable for the humid environment in the south. ； u The control methods include switching control, 4-20mA control, and RS485 communication control. Normal use generally uses switching control. There are various control methods, and the oil controller can monitor the opening and closing status of the valve through RS485 communication. ； u There are no solenoid coils and manual valves outside the valve, which reduces human intervention in the valve. ； u The valve accuracy can be controlled within one ten thousandth ； u During the oiling process, the flow resistance is small, the oiling speed is fast, the efficiency is high, and the energy is saved. ； u The seal is resistant to various chemical reagents and is resistant to aging after long-term use. ； u For various working conditions, the performance is superior to that of electro-hydraulic valves.
