What are the advantages of electric control valves?
Date:Aug 13, 2019
1. Good adjustment function
The adjustment function is one of the main functions of the regulating valve</a>, 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 regulating 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. 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 regulating 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
Overcoming the differential pressure function is a prerequisite for ensuring cutting, and is inseparable from the cutting function. The double seat valve allows for a large differential pressure, but the leakage is large; the single seat valve has a small leak, but allows a small differential pressure. The full-function ultra-light regulating valve better solves the problem of large pressure difference and small leakage, which allows the pressure difference to reach the PN value.
4. Strong corrosion resistance
The corrosion-resistant function ensures 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 control valve uses corrosion-resistant, erosion-resistant materials and precautions, and has a good anti-corrosion function.
5. Anti-blocking function is good
The anti-blocking function can effectively ensure the normal operation of the valve in the case of dirty media. The full-featured ultra-light regulating valve developed according to the principle of fluid mechanics has the characteristics of simple flow path, less dead zone vortex, medium straight-through, easy to settle, self-cleaning function, and has become high viscosity, suspension, pulp, thick slurry, and Products used in applications such as granules and dirty media.
6. High compressive strength
The pressure resistance function is a safety guarantee for the valve. The full-function ultra-light regulating 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. Good temperature resistance
The temperature resistance function is the guarantee that the valve adapts to different temperatures. The full-featured ultra-light regulating 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 packing ensures the reliability of the valve stem sealing at high temperature.
8. Good appearance and light weight
The appearance and weight function reflect the miniaturization, light weight and instrumentation of the valve. The all-function ultra-light control valve adopts an integrated valve body structure and optimized appearance design, and is connected with the 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 control valves, the full-featured ultra-light control valve has a weight reduction of 60-80%, which is 40-60% lighter than the CV3000 and the compact control valve. Taking the electric valve of DN100 as an example, the sleeve regulating valve weighs about 150Kg, while the full-function ultralight regulating valve weighs only 40Kg (electronic) and is 73% lighter.
