1. Good adjustment function The regulating function is one of the main functions of the regulating valve, manifested as ① flow characteristics; ② Adjustable ratio R; ③ Small opening working performance; ④ Flow coefficient; ⑤ Adjust the speed. Fully functional ultra light regulating valve R=100, ensuring good small opening adjustment; The Kv value is large, which is 2-3 times that of single and double seat valves and sleeve valves.
2. Good cutoff function The cut-off function reflects the inherent quality of the valve. The standard leakage rate of a straight stroke valve is usually 10 to 10; The standard leakage rate of the fully functional ultra light regulating valve is 10, which is 100-1000 times higher than that of single and double seat valves and sleeve valves.
3. Overcoming large pressure difference Overcoming the pressure difference function is a prerequisite for ensuring cutoff and is inseparable from the cutoff function. The double seat valve allows for a large pressure difference but a large leakage; The single seat valve has small leakage, but allows for a small pressure difference. The fully functional ultra light regulating valve effectively solves the problem of large pressure difference and small leakage requirements, and its allowable pressure difference can reach PN value.
4. Strong corrosion resistance function The corrosion resistance function ensures that the valve can resist damage such as corrosion, erosion, and cavitation of the medium, extending its service life. The fully functional ultra light regulating valve adopts corrosion-resistant and erosion resistant materials and preventive measures, which has good corrosion resistance function.
5. Good anti blocking function Good anti blocking function can effectively ensure the normal operation of the valve in unclean media environments. The full function ultra light control valve developed and designed according to the principle of Fluid mechanics has the characteristics of simple flow path, less dead zone vortices, no easy sedimentation of medium through, and good self-cleaning function. It has become the preferred product for the application of high viscosity, suspension, pulp, thick pulp, particles and other dirty media.
6. High compressive strength The pressure resistance function is the safety guarantee of the valve. The fully functional ultra light regulating valve body structure is a single piece integrated structure, which improves the structural integrity of the pressure limit and enhances the compressive strength. The high-pressure adopts a forged structure, further improving the compressive strength of the valve body, with a compressive strength of over 32MPa.
7. Good temperature resistance function The temperature resistance function ensures that the valve can adapt to different temperatures. The fully functional ultra light regulating valve adopts an elastic hard seal that combines rigidity and flexibility to solve the problem of core and seat package jamming caused by expansion under high temperature; The use of high-temperature wear-resistant packing ensures the reliability of the valve stem sealing under high temperatures.
8. Good appearance and light weight The appearance and weight function reflect the miniaturization, lightness, and instrumentation characteristics of the valve. The fully functional ultra light regulating valve adopts an integrated valve body structure and optimized appearance design, and is connected to the actuator through a simple and reliable direct connection. It has a compact structure, small size, light weight, and good appearance. Compared with traditional leading products such as single seat, double seat, and sleeve regulating valves, the fully functional ultra light regulating valve has a weight reduction of 60-80%, and is 40-60% lighter than CV3000 and precision small regulating valves. Taking the DN100 electric valve as an example, the sleeve regulating valve weighs about 150Kg, while the fully functional ultra light regulating valve only weighs 40Kg (electronic type) and is 73% lighter.
