Product specification
Needle valve with highly precise bore made of brass and stainless steel with FPM gasket for extremely small flow rates of gases and liquids.
The needle valve allows an outstandingly exact regulation of flow. The sliding needle with conical ground surface reciprocates in a nozzle aperture and varies the aperture cross-section linearly with the stem turn.
The throttle cross-section is reproducible at exact stem setting.
Hysteresis of the area characteristic is eliminated by a spring.
