Kofloc 2412M Flow Meters and Controllers for Liquid

Kofloc 2412M Flow Meters and Controllers for Liquid: This needle valve has been designed to control minute gas and liquid flows with precision and ease. The design allows the rotation of the regulating screw to transform into linear motion of the needle without subjecting the needle to gaps and/or vibrations produced by the screw, so smooth, stable flows can be ensured.

A needle valve is the typical flow control valve that controls the flow rate based on the change of resistance of the flow channel using an acicular or rod-shaped needle to adjust the opening of the flow channel that functions as a small orifice. KOFLOC offers simple-type, precision-type, and various other needle valves, and also manufactures flow controllers having a combination of a needle valve and diaphragm as well as proportional solenoid valves that electrically control the flow rate.

Features

1. Non-Rotary Needle Structure

The 2412M utilizes a needle that moves strictly in a vertical, linear motion without rotating.

Importance for Liquids: In liquid control, a rotating needle can cause “pumping” or localized pressure shifts that lead to inconsistent drip rates. The non-rotary design ensures a smooth, constant flow from the moment of adjustment.

2. Superior Resolution (Fine Tuning)

With over 10 turns of the handle, the 2412M allows for “micro-dosing.” This makes it ideal for applications where a user needs to control a liquid flow down to a few milliliters per minute.

3. Minimal Dead Space

The internal body of the 2412M is designed to minimize “dead volume.” This prevents liquids from stagnating inside the valve, which is essential for biological fluids or liquids that may degrade or crystallize over time.
