Control valve features a total of eight, full-featured ultra-light valve eight features is outstanding, it is referred to as the "full functional valve".
1, adjusting function
Regulation function is one of the main function of regulating valve, showed the flow characteristics; the adjustable ratio R; the small opening performance; the flow coefficient; regulating speed. Full-function ultra-light valve R=100, so that a small opening regulation is good; Kv value of large, single seat valve, sleeve valve 2 ~ 3 times.
2, good cut off function
Cut off the intrinsic quality function reflect valve. Standard straight trip valve leakage rate is usually 10 ~ 10; full-featured ultra-light valve standard leak rate is 10, than the single seat valve, sleeve valve high 100 ~ 1000 times.
3, to overcome the large pressure difference
To overcome the pressure function is to ensure that the premise of cut, and cut off the integral function. Two-seat valve allows a large pressure difference, but the leakage of large; single-seat valve leakage is small, but allows a small pressure difference. Full-function ultra-light valve solves the pressure difference is large, leak-proof and require a small problem, which allows the value of pressure up to PN.
4, corrosion resistance strong function
Corrosion resistant valves feature to ensure media corrosion, erosion, cavitation and other damage, prolong the service life. Full-function ultra-light control valve with the corrosion, erosion resistant materials and the prevention measures, has good corrosion resistance function.
5, the anti-blocking function
The anti-blocking function can effectively ensure the valve is not clean media occasions normal operation. Full function in accordance with the development of the principle of fluid mechanics design ultra-light valve, with the flow path is simple, low swirl dead zone, through the media is not easy to subside, good self-cleaning function, have become the products of choice for high viscosity, suspension, pulp, thick, containing particles do not clean medium of applications.
6, high compressive strength
Pressure safety valve function is guaranteed. Full-function ultra-light valve body structure as a single integrated structure, improve the structural integrity of pressure boundaries, improve the compressive strength. High use of forged structure, to further improve the compressive strength, the compressive strength can reach more than 32MPa.
7, good temperature resistance function
Temperature function is to ensure the valve to adapt to different temperatures. Full-function ultra-light control valve with a rigid-flexible elastic seal leads to the core, a package of solutions to ensure the reliability of high temperature expansion; stem seal under high temperature using high temperature resistant filler.
8, good appearance and light weight
The appearance and weight function valve miniaturization, lightweight, instrument characteristics. Full-function ultra-light control valve body using an integrated optimization of structure and exterior design, and with direct method is simple, reliable and execution mechanism is connected, compact structure, small size, light weight, good appearance. Full-function ultra-light control valve with the traditional leading products single-seat, two-seater, sleeve valve compared, its weight was decreased by 60-80%, CV3000 and fine small valve has a light 40-60%. To DN100 electric valve, for example, sleeve valve weighs about 150Kg, while the full-featured ultra-light control valve weighs only 40Kg (Electronic), light 73%.
