KOFLOC MODEL 2412D SERIES Large-Flow Precision Needle Valve
Quick Review
• Precision Control
The KOFLOC Large-Flow Precision Needle Valve MODEL 2412D SERIES is designed to control relatively large flows with precision and ease. This valve is a magnified version of the Kofloc Precision Needle Valve MODEL2412 SERIES for stable control of flows ranging from 50 L/MIN to 300 L/MIN (0.1 MPa).
•Cleanness
The housing of the KOFLOC Large-Flow Precision Needle Valve MODEL 2412D SERIES is thoroughly cleaned to assure flow control without contamination.
•KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
• Durability
The KOFLOC Large-Flow Precision Needle Valve MODEL 2412D SERIES has excellent durability and uses special grease on its non-wetted parts.
• Non-Rotating Needle
The design of The KOFLOC Precision Needle Valve MODEL 2412 SERIES transforms the rotation of the regulating screw to into linear motion of the needle without subjecting it to gaps and vibrations produced by the screw, to ensure stable and even control of minute flow.
