There are a total of eight electric control valves , and all eight functions of the full-function ultra-light electric control valve are excellent, so they are called "full-function valves."
1. Good adjustment function The adjustment function is one of the main functions of the electric control valve, which is expressed as ① flow characteristics; ② adjustable ratio R; ③ small opening performance; ④ flow coefficient; ⑤ adjustment speed. Full-featured ultra-light electric control valve R = 100, making small opening degree good adjustability; Kv value is large, which is 2 to 3 times of single and double seat valve and sleeve valve.
2. Good cut-off function The cut-off function reflects the intrinsic quality of the valve. The standard leak rate of straight-stroke valves is usually 10 to 10; the standard leak rate of full-function ultra-light pressure electric regulating valves is 10, which is 100 to 1000 times higher than that of single and double seat valves and sleeve valves.
3. Overcoming large differential pressure is a prerequisite for cutting off and is inseparable from cutting off function. The double seat valve allows a large pressure difference, but the leakage is large; the single seat valve has a small leakage, but the pressure difference is small. The full-function ultra-light electric regulating valve better solves the problem of large pressure difference and small leakage requirements. It allows the pressure difference to reach PN.
4. Anti-corrosion function The strong anti-corrosion function guarantees that the valve can resist the damage of corrosion, erosion and cavitation of the medium and prolong the service life. Full-function ultra-light electric control valve adopts corrosion-resistant and erosion-resistant materials and preventive measures, and has good corrosion resistance.
5. Good anti-blocking function Only good anti-blocking function can effectively ensure the normal operation of the valve in the case of dirty media. Full-featured ultra-light electric control valve developed and designed in accordance with the principles of fluid mechanics. It has the characteristics of simple flow path, few dead zone vortices, direct passage of the medium, and easy sedimentation. The product of choice for applications containing dirty media such as particles.
6. High pressure resistance is the safety guarantee of the valve. The body structure of the full-function ultra-light electric regulating valve is a one-piece integrated structure, which improves the structural integrity of the pressure limit and the pressure resistance. The high pressure adopts a forged structure, which further improves the pressure strength of the valve body, and the pressure strength can reach more than 32MPa.
7. Good temperature resistance function The temperature resistance function is a guarantee for the valve to adapt to different temperatures. The full-featured ultra-light electric control valve adopts a rigid and flexible combination of elastic and hard seals to solve the core and seat package card problems caused by expansion at high temperatures; the use of high-temperature wear-resistant packing to ensure the reliability of the valve stem sealing at high temperatures.
8. Good appearance and light weight The appearance and weight function reflect the characteristics of valve miniaturization, light weight and instrumentation. Full-function ultra-light electric control valve adopts integrated valve body structure and optimized appearance design, and is equipped with a simple and reliable direct connection method to connect with electric actuators
. It has a compact structure, small size, light weight and good appearance. Compared with the traditional single-seat, double-seat, sleeve electric control valve, the full-featured ultra-light electric control valve has a weight reduction of 60-80%, and is 40-60% lighter than the CV3000 and the compact electric control valve. Taking the DN100 electric valve as an example, the sleeve electric regulating valve weighs about 150Kg, while the full-featured ultra-lightweight electric regulating valve weighs only 40Kg (electronic) and is 73% lighter.
