The BD-6000 series pneumatic "V" type movable hard-sealed ball valve has the characteristics of compact structure, good sealing performance, and long service life. It also has both regulating and cutting functions. The sealing ring can be in the form of either metal hard seal or soft seal, allowing for selection to meet different working conditions. The flow path is simple, the flow capacity is large, the adjustable ratio is up to 1:100; when the V-shaped ball core and the sealing ring are closed, a shear effect occurs, which can cut the fibers and extruded particles in the medium, and has the self-cleaning function of the ball core. It is particularly suitable for paper pulp, sewage, and other media containing fibers and solid particles, and is used for cutoff or regulation control of process media, widely applied in the papermaking, petroleum, chemical, coal chemical, steel, power, and pharmaceutical industries.
This product has the following features:
1. The valve body adopts an integral design, avoiding leakage caused by the central flange connection in ordinary ball valves.
2. The valve core is designed with a special V-shaped notch, and the valve has approximately equal percentage flow characteristics. This design enables the valve to have precise control performance, while during the movement between the valve core and the sealing seat, a large shear force and wiping performance are generated, which can cut the fibers in the medium containing fibers and solid particles, and has a self-cleaning function for media containing solid particles.
3. The valve core is fixed by two bearings on the upper and lower valve stems, with extremely high rotational accuracy and stability.
4. The flow resistance is small, and the flow capacity is 2-3 times that of ordinary single-seat regulating valves, making the V-type ball valve have a higher cost performance.
5. Due to the valve core being smaller than a hemisphere, the structure is lightweight. The valve has the advantages of small size and light weight, and requires less opening and closing torque than ordinary 0-type ball valves, making it easier to operate.
6. The V-type valve has a wide range of applications. Depending on different working conditions, soft-sealed and hard-sealed options can be provided. The valve seat and valve core can use sprayed hard alloy or tungsten carbide for sealing materials to meet different requirements.
The BD-6000 series pneumatic "O" type cut-off ball valve is a two-piece ball valve structure. The valve body is composed of the main and auxiliary parts, and the ball core adopts full diameter. The rated flow coefficient is large, and the flow resistance is negligible. The surface of the soft-sealed ball core is hardened by a special process to make it smooth and wear-resistant, and the sealing material of the valve seat is carbon fiber reinforced polytetrafluoroethylene; the surface of the hard-sealed ball core is treated by spraying tungsten carbide, with extremely strong wear resistance, and the sealing material of the valve seat is stainless steel clad titanium alloy, with a long service life. The actuator selects a high-performance double piston gear rack structure, with high transmission efficiency and a compact structure. Or it can be an electric actuator, widely used in petroleum, chemical, power, pharmaceutical, papermaking and other industries.
This product has the following features:
1. The sealing ring adopts a unique elastic lip seal technology, ensuring zero leakage for the cutting requirement, and the unique automatic compensation function enables the valve to have a longer service life.
2. The surface of the ball core is hardened by a special process after grinding and polishing, smooth and wear-resistant, reaching a mirror-like effect;
3. The internal valve stem structure ensures that the valve stem cannot fly out due to pressure during use, providing better safety and rigidity;
4. The ball core adopts a full-diameter straight-through flow path, the same as the inner diameter of the pipeline, with the largest flow capacity and the smallest flow resistance.
5. The ball core only needs to rotate 90° to complete full opening or full closing, the action is simple and rapid;
6. The entire machine is designed according to fireproof and anti-static standards, suitable for various special occasions;
