Kofloc Large Capacity Precision Needle Valve Model 2412D SERIES

Description

The Kofloc 2412D SERIES addresses a specific challenge in fluid dynamics: the loss of control precision as flow capacity increases. While standard large valves often suffer from “jumpy” adjustments or internal wear at high velocities, the 2412D utilizes a non-rotary stem mechanism. In this design, the needle moves linearly without rotating against the seat. This prevents the “galling” or seat deformation that typically occurs in large-capacity valves, ensuring a hermetic seal and consistent performance over a long service life.

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.

Features

Non-Rotary Needle Mechanism: Linear motion prevents friction-based wear, eliminates particle shed, and ensures stable settings.
Superior Repeatability: The non-rotating design ensures that the valve returns to the exact same flow rate at the same position, every time.
SUS316 Stainless Steel Construction: Provides maximum chemical compatibility and durability for aggressive gases or high-purity water.

Applications

Industrial Gas Manifolds: Regulating the main supply of Nitrogen, Argon, or Oxygen for entire production lines.
Pilot Plants & Scale-up Rigs: Controlling high-volume feedstocks where laboratory-grade precision is still required.
High-Power Cooling Systems: Precisely balancing the flow of deionized water or coolant to sensitive electronics.
