Full-featured ultra-light control valve and control valve of the comparative advantage

Control valve features a total of nine, full-function ultra-light control valve nine functions are excellent, it said full-featured valve. Good regulation function Regulating valve is one of the main functions, manifested as flow characteristics; ② adjustable R; ③ small opening performance; ④ flow coefficient; ⑤ adjust the speed. Full-featured ultra-light control valve R = 100, so that small opening adjustment is good; Kv value, single and double seat VALVES, sleeve valve 2 to 3 times. Cut-off function good Shut off function reflects the internal quality of the valve. Straight stroke valve standard leakage rate is usually 10 to 10; full-featured ultra-light control valve standard leak rate of 10, single or double seat valve, sleeve valve 100 to 1000 times higher. To overcome the pressure differential overcome the differential pressure function is to ensure that the cut-off premise, and the cutting function is inseparable. Double-seat valve to allow large pressure, but a large leak; single-seat valve leakage is small, but allows small pressure. Full-featured ultra-light control valve to better solve the pressure, leakage and the small problem, which allows the pressure up to PN value. Anti-corrosion function Corrosion-resistant function to ensure that the valve can resist corrosion, erosion, cavitation and other damage, to extend the service life. Full-featured ultra-light control valve with corrosion-resistant, erosion-resistant materials and preventive measures, has good corrosion resistance. Good anti-blocking function Good anti-blocking function can effectively ensure the valve is not clean media in the normal operation. Developed in accordance with the principles of fluid mechanics designed full-function ultra-light control valve, with a simple flow path, swirling less dead zone, the media is not easy to settle settlement, self-cleaning features, has become a high viscosity, suspension, pulp, Particles and other clean media applications where the preferred product. High compressive strength is the valve pressure guarantee safety features. Full-featured ultra-light control valve body structure for the single-piece structure, improving the structural integrity of the pressure limit, improve the compressive strength. Forged high-pressure structure, to further enhance the compressive strength of the valve body, compressive strength up to 32MPa or more. Temperature function Good temperature function is to ensure that the valve to adapt to different temperatures. Full-featured ultra-light control valve with rigid and flexible combination of flexible hard seal to solve the high temperature expansion caused by the core, Block package card problem; the use of high temperature wear-resistant packing to ensure the reliability of the valve stem seal at high temperature. Good appearance, light weight, appearance and weight function reflects the small valve, light weight, instrumentation features. Full-featured ultra-light control valve with integrated valve body structure and appearance of optimal design, coupled with a simple, reliable direct connection with the implementing agencies connected, compact structure, small size, light weight, good appearance. The full-function ultralight control valve has a 60-80% reduction in weight compared to conventional leading single-seat, two-seat, sleeve control valves and is 40-60% lighter than CV3000 and precision control valves. To DN100 electric valve, for example, sleeve control valve weighs about 150Kg, while full-function ultra-light control valve weighs only 40Kg (electronic), light 73%.
