Description
The pneumatic bellow seal noise reduction control valve core adopts the upper guide structure, the valve structure is compact, and there is an S-streamline channel, which makes the pressure drop loss small, the flow rate is large, the adjustable range is wide, the flow characteristic accuracy is high, and it conforms to the IEC534 standard. The upper valve cover adopts a bellows sealing structure, and the bellows single-seat regulating valve is suitable for the adjustment of extremely toxic, flammable, explosive, volatile and rare precious metal media. In addition, the valve can also be used in vacuum applications.
Product Features
1. The pneumatic bellow seal noise reduction control valve has a compact structure, few parts and easy maintenance.
2. The metal valve core is suitable for a variety of working occasions, reaching the IV level leakage standard, and the soft sealing structure valve core reaches the VI level leakage standard.
3. The valve body of the regulating valve is designed as a low-flow resistance flow channel of equal cross-section according to the principle of fluid mechanics, and the rated flow coefficient is increased.
4. The adjustable range is large, and the inherent adjustable ratio is 50.
5. The actuator of the regulating valve adopts a multi-spring structure, which reduces the height and weight.
6. The bellows-sealed regulating valve forms a seal on the moving valve stem to prevent fluid leakage.
7. It can be equipped with a thermal insulation jacket, which is used for the occasions where the fluid is easy to crystallize and solidify after cooling and cause blockage.
