The BD-7000 series electric single-seat control valve, the series of electric single-seat control valves, feature a compact structure, small size, light weight, and sensitive operation. The flow channel is in an S-shaped streamline, with low pressure drop loss, large flow capacity, precise flow characteristics, and convenient maintenance. It can be used in demanding working conditions. It is particularly suitable for applications where the allowable leakage is small, the pressure difference before and after the valve is not large, and the fluid is clean. It is widely used in industries such as petroleum, chemical engineering, power, textiles, papermaking, etc.
This product has the following features:
1) The regulating valves of our company all adopt S-shaped valve bodies, which have excellent pressure resistance and absolutely reliable structural strength. This ensures that the valves will not cause deformation or increase internal leakage, which are common problems of domestic regulating valves, at the installation site. The flow channel inside the valve is of low resistance, S-shaped flow channel, making the entire machine have very small flow resistance, wide adjustable range, and high flow characteristic accuracy.
2) According to different working conditions, different structural and fully interchangeable throttling components, also known as valve internals, can be selected. The flow characteristics include equal percentage, linear, and quick opening, etc.
3) The internal components of the P series electric single-seat valve consist of valve seat, valve core, and valve stem, and adopt an upper guide structure. It has the advantages of compact structure, light weight, high adjustment accuracy, small pressure drop loss, high flow characteristic accuracy, large guiding area, and vibration prevention. It is particularly suitable for working conditions with small leakage and small pressure difference before and after the valve.
The BD-7000 series electric sleeve regulating valve is a pressure-balanced regulating valve. It adopts sleeve guidance and pressure-balanced double-sealed valve core structure. The flow channel is of S-flow line type, and the overall operation is stable. It has the characteristics of large allowable pressure difference, precise flow, low noise, etc. It is particularly suitable for occasions with large flow, large pressure difference before and after the valve, and low leakage requirements. The product is widely used in the automatic control systems of industrial departments such as chemical, petrochemical, chemical fiber, power, metallurgy, and environmental protection.
This product has the following features:
1) The flow channel adopts an S-shaped structure, which can suppress the occurrence of vortices caused by complex flow paths and the complex and irregular flow caused by sudden expansion of the flow path, thereby achieving efficient and stable medium flow.
2) It adopts modular design, with good interchangeability and universality; by changing different sleeves, different flow coefficients and different flow characteristics can be obtained.
3) Balanced structure: The unbalanced force on the valve core is greatly reduced; at the same time, it also has damping operation, which is conducive to the stable operation of the control valve, so it can be used in applications with large pressure difference and low noise.
4) Installation and maintenance are convenient: The valve seat is pressed onto the valve body through the valve cover, without using threaded connection, making installation and maintenance convenient.
