Multi stage regulating valve

 Overview of products

 MD/DTZ multi-stage regulating device against high pressure difference is widely used in industries such as petroleum, chemical industry, metallurgy, power station, urban water supply and sewage treatment, etc., which effectively reduces the pressure difference between the inlet and outlet of the regulating valve, reduces the impact and vibration of fluid on the valve core, improves the flow characteristics, prolongs the service life of the regulating valve, and has good sealing performance and is not easy to block. Has successfully declared the national invention patent with the patent number (201210474678. 4 ).

 Performance, characteristics and main technical indicators:

 when there is a high pressure difference between the two ends of the device, it can withstand the pressure difference of 6. 0Mpa for long-term use, with high and stable adjustment precision, light switch and less scour at the high pressure difference. Not suitable for erosion, reliable sealing, small vibration, low noise, cavitation resistance, long service life, and improved flow stability and linearity.
