2204 SERIES
Model 2204 Variable Primary Pressure Flow Controller is a control valve that always keeps flows at a constant rate under a given constant level of secondary pressure (outlet pressure) even when the primary pressure (inlet pressure) fluctuates. The built-in precision needle valve accurately controls flows to the set flow rate, including ultra-minute flows.

2203 SERIES
A flow controller is a differential pressure regulator designed to control minute gas flows with precision and keep a certain constant flow rate. Model 2203 Variable Secondary Pressure Flow Controller is a control valve that keeps mass flows at a constant rate under a given constant level of supply pressure even when the load pressure on the secondary side (outlet side) fluctuates, and its construction is designed so that the performance of its precision control over flows to the set flow rate is maintained by the incorporated precision needle valve without being affected by such fluctuations.

2450 SERIES
This bellows seal type needle valve has been specifically developed so that it can satisfy the requirements for such areas in which leak is a concern of vital importance. Model 2450 Bellows Needle Valve has a construction to drastically prevent fluid leaks. In addition, it is outstanding in heat resistance and corrosion resistance, so the customer can use it with peace of mind not only in such adverse conditions where high vacuum, high pressure, high temperature or extremely low temperature is present but also for corrosive, toxic or costly fluids.

2412M
This is an enhanced model of the KOFLOC Precision Needle Valve Model 2412 (see page 102), which now incorporates a multidial that allows the user to set desired flow rates by dial operations. This valve makes the most of the rotationto-flow linearity and repeatability performance of the 2412 needle.

2412 SERIES
This needle valve has been designed to control minute gas and liquid flows with precision and ease. 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.
