CKD Dial Needle Valve Needle Valve (Oil-free Type) DVL-N-06-H44-080 1 pc

Catalog number: DVL-N-06-H44-080 Features: ● A rotary needle valve with linear flow characteristics is used. ● Linear flow characteristics proportional to the needle rotation speed are obtained, and the needle rotation speed can be displayed numerically on the dial. ● Numerical adjustments can be easily performed by anyone, so it is accurate and highly reproducible, and adjustment errors can be prevented. ● Adjustments are quicker, and the labor hours for changing setups and other tasks can be significantly reduced. ● Numerical management of flow rates is easy, and the dial display shows it at a glance, making it possible to quantify the work manual. ● The needle can be easily fixed with a sliding lock lever, making adjustment work easier. ● The mounting part rotates 360°, so you can freely choose the mounting and installation method, such as bottom, side, or panel mounting, and no mounting bracket is required. Applications: ● For flow rate adjustment and management of air blow and purge gas. Specifications: ● Compatible tube outer diameter D (mm): 4 ● Compatible tube outer diameter (mm): 4 ● Operating pressure (MPa): 0 to 0.7 ● Fluid used: Compressed air / N2 gas / low vacuum ● Fluid temperature (℃): 5 to 60 (but do not freeze) ● Pressure resistance (MPa): 1.5 ● Ambient temperature (℃): 0 to 60 ● Needle control range (rotations): 1 to 12 ● Flow rate (L/min (ANR)): 80 ● Effective cross-sectional area ([[MM2]]): 1.2 ● Connection type: Inline ● Maximum operating pressure: 0.7MPa ● Negative pressure: -100 (kPa) Material / Finish: ● Resin part: Polybutylene terephthalate, polyacetal, polyamide ● Metal part: Brass, stainless steel ● Gasket part: Hydrogenated nitrile rubber, fluororubber Caution: ● Fluid temperature / ambient temperature: Do not freeze. ● Please note that depending on the air quality (dew point), there is a risk of freezing due to adiabatic expansion. ●The flow rate is the atmospheric pressure converted value at a pressure of 0.5 MPa. ●The flow rate of the flow rate type indicates the guideline flow rate at 0.5 MPa. ●All brass parts are electroless nickel plated.
