DATASHEETNEEDLE VALVEFeatures- Our original special shape plug allows for highly accurate flow control.
- Shutoff valve and rubber seat allow for complete sealing.
- Independent from shutoff valve, it maintains high-accuracy control function fora long period.
- Inspection and cleaning of inside of the valve can be performed without
dismounting it from the pipe, by removing the cap (15mm, 20mm).
- Integrally molded body that is light weight, robust and compact.
