KOFLOC MODEL 2412M SERIES Precision Needle Valve with Multi-Dial
Quick Review
• Precision Control
The KOFLOC Precision Needle Valve MODEL 2412M SERIES is designed to control minute flows with precision and ease. The Dial provides an easy way to estimate actual flow because of the good repeatability, and linear correlation between the flow and the rotation. It has been widely used in numerous applications from general industrial applications to analytical equipment.
•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.
• Numerous Variants
The KOFLOC Precision Needle Valve MODEL 2412M SERIES has numerous variants with different optimum flow ranges and connection alignments.
• Non-Rotating Needle
The design of the KOFLOC Precision Needle Valve MODEL 2412M 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.
• Wide operating temperature range
The needle orifice of the KOFLOC Precision Needle Valve MODEL 2412M SERIES has a temperature compensating structure (US P.A.F.) achieving the characteristic of 0.3%/˚C for gas temperatures between 15 ˚C to 35˚C.
