The electric control valve has a total of eight functions. The full-function ultra-light electric control valve has excellent functions, so it is called “full-function valve”.
1. The adjusting function is one of the main functions of the electric regulating valve, which is characterized by 1 flow characteristic; 2 adjustable ratio R; 3 small opening working performance; 4 flow coefficient; 5 adjusting speed. The full-function ultra-light electric control valve R=100 makes the small opening degree adjustable; the Kv value is large, which is 2 to 3 times that of the single double seat valve and the sleeve valve.
2, The cut-off function is good, the cut-off function reflects the inherent quality of the valve. The standard leakage rate of the straight stroke valve is usually 10 to 10; the standard leakage rate of the full-function ultra-light pressure electric control valve is 10, which is 100 to 1000 times higher than that of the single and double seat valve and the sleeve valve.
3, Overcome the pressure difference to overcome the pressure difference function is to ensure the cutting off the premise, and the cutting function is inseparable. The double seat valve allows for large differential pressures but large leaks; single seat valves have low leakage but allow for small differential pressures. The full-featured ultra-light electric control valve better solves the problem of large pressure difference and small leakage, which allows the pressure difference to reach the PN value.
4, Corrosion resistance, strong corrosion resistance function to ensure that the valve can resist the corrosion, erosion, cavitation and other damage of the medium, and prolong the service life. The full-featured ultra-light electric control valve adopts corrosion-resistant and erosion-resistant materials and preventive measures, and has good corrosion resistance.
5, Anti-blocking function, good anti-blocking function can effectively ensure that the valve operates normally in the case of dirty media. The full-featured ultra-light electric control valve developed according to the principle of fluid mechanics has the characteristics of simple flow path, less dead zone vortex, medium straight-through is not easy to settle, and self-cleaning function is good. It has become high viscosity, suspension, pulp, thick paste, The preferred product for applications where dirty media such as granules are used.
6. Pressure resistance High pressure resistance function is the safety guarantee of the valve. The full-function ultra-light electric control valve body structure is a one-piece integrated structure, which improves the structural integrity of the pressure limit and improves the compressive strength. The high pressure adopts a forged structure, which further improves the compressive strength of the valve body, and the compressive strength can reach 32 MPa or more.
7, Temperature resistance, good temperature resistance is the guarantee of the valve to adapt to different temperatures. The full-featured ultra-light electric control valve adopts the rigid and flexible elastic hard seal to solve the core and seat card problem caused by the expansion under high temperature; the high-temperature wear-resistant filler ensures the reliability of the valve stem sealing at high temperature.
8, Good appearance, light weight appearance and weight function reflects the valve's miniaturization, light weight, instrumentation features. The all-function ultra-light electric control valve adopts an integrated valve body structure and optimized appearance design, and is connected with the electric actuator in a simple and reliable direct connection mode. The structure is compact, small in size, light in weight and good in appearance. Compared with the traditional leading single-seat, two-seat, and sleeve electric control valves, the full-featured ultra-light electric control valve has a weight reduction of 60-80%, which is 40-60% lighter than the CV3000 and the compact electric control valve. Taking the electric valve of DN100 as an example, the sleeve electric control valve weighs about 150Kg, while the full-function ultralight electric control valve weighs only 40Kg (electronic type), which is 73% lighter.
