Imported from Germany, it has high-precision flow regulation capability and can achieve precise control of small flow rates. $r $n adopts needle or V-port valve cores, with needle valve cores having high sensitivity for adjustment, while V-port valve cores are not easily broken, and can work stably even under high pressure differentials. The adjustment accuracy of $r $n is high, and the minimum adjustment CV can reach 0.001. $r $n has good pressure resistance performance, up to 32MPa or even higher
Electric needle valve (four-way ball valve)
Product performance: (imported from Germany)
It has high-precision flow regulation capability and can achieve precise control of small flow rates.
Special valve core design, such as using needle or V-port valve cores, has high sensitivity for needle valve core adjustment, while V-port valve cores are not easily broken, and can work stably even under high pressure differences.
High adjustment accuracy, with a minimum adjustment CV of 0.001.
Has good pressure resistance, up to 32MPa or even higher.
Materials used:
The valve body material usually includes stainless steel (such as 304, 316, etc.), cast steel, forged steel, etc., which have good corrosion resistance and strength.
The valve stem, valve seat, valve core and other components are also mostly made of stainless steel material, ensuring the reliability and durability of the valve.
The fillers are generally polytetrafluoroethylene, flexible graphite, etc., ensuring good sealing performance.

Accessories available: locator, air filter pressure reducing valve, limit switch, valve position feedback device, emergency device, handwheel mechanism, etc.
Purpose:
Widely used in chemical engineering, scientific research institutions, laboratory experimental equipment, industrial equipment for mass production, etc., it is used to control the small flow of chemicals, fuels, fragrances or other additives, and is also suitable for regulating the mainstream flow of liquids, steam and other media.
Packing:
It is usually packed in a solid carton or wooden case, and there may be foam plastics and other cushioning materials inside to protect the valve from damage during transportation.
Instructions for Use:
Before installation, it is necessary to ensure that there are no impurities in the pipeline to avoid damaging the valve.
Choose the appropriate form of action (air open or air closed) based on the working conditions and adjustment requirements.
Connect the gas source or power supply and wire it correctly according to the requirements of the actuator.
Positioners and other accessories can be equipped as needed to improve adjustment accuracy and control effectiveness.
During use, pay attention to the cleanliness of the medium and avoid impurities blocking the throttling gap.
If manual operation is required, the handwheel mechanism can be used for adjustment.
Electric needle valve (four-way ball valve)After-sales service
