KOFLOC MODEL 2203 SERIES Variable Secondary Pressure Flow Controller Valve
Quick Review
• Precision Control
The KOFLOC Variable Secondary Pressure Flow Controller Valve MODEL 2203 SERIES is a control valve for precise control of minute gas flow and maintaining constant flow under fluctuating secondary pressure (outlet), provided the supply pressure remains constant.
• 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.
• Non-Rotating Needle
Constructed using high precision parts, the design of the KOFLOC Variable Secondary Pressure Flow Controller Valve MODEL 2203 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.
•Cleanness
The housing of the KOFLOC Large-Flow Precision Needle Valve MODEL 2412D SERIES is thoroughly cleaned to assure flow control without contamination, suitable for highly sensitive scientific or analytical applications.
• Free from Secondary Pressure Fluctuations
Since the KOFLOC Variable Secondary Pressure Flow Controller Valve MODEL 2203 SERIES is not affected by pressure loss of the secondary (outlet) system, which makes it a must-have preliminary valve in many flow control mechanisms.
