Actual example of flow control Fig. A Flow control with needle valve Our mechanical valves can be used for gas flow control in many Pressure gauge ways. An example of the most popular method of constant flow con- trol with a needle valve and flow controller is explained here.
(1) Flow control with needle valve The needle valve controls the opening of a small orifice in a chan- nel with a bar-shaped needle, controlling the flow by changing the Load channel resistance. The valve thus acts as a resistance. The flow Constant Pressure pressure Needle Constant changes when the pressure applied to the valve changes. Therefore, regulating valve flow a pressure regulator is provided in the preceding stage as shown in valve Fig. A to make the pressure applied to the valve constant, thereby obtaining constant flow. This is an inexpensive method which is com- monly used when the pressure loss on the valve outlet side does not change. Use a simplified type, precision type, or bellows type needle valve according to the usage. Fig. B Flow control with variable primary pressure flow controller (2) Flow control with variable primary pressure type flow controller The variable primary pressure (supply pressure) type flow controller is Flow controller made by combining the needle valve (1) and a pressure regulator. It can keep the flow constant even if the primary-side pressure chang- Ｆ Ｃ Load Pressure change es. (Fig. B). Constant flow C (3) Flow control with variable secondary pressure type flow controller In methods (1) and (2), the flow will change if the pressure loss of a load in the subsequent stage is large. In that case, a variable second- ary pressure (outlet-side pressure: load pressure) type flow controller is used to control flow according to the flow sheet shown in Fig. C. This flow sheet is complete with respect to pressure change, and is Fig. C Flow control with variable secondary pressure flow controller used basically for our gas mixing equipment. The primary-side pres- sure is controlled by a regulator, and the flow controller immune to pressure changes on the secondary side enables flow control free of Pressure gauge the influence of the primary and secondary pressure.
Flow controller Pressure change
Ｆ Ｃ Load Flow control characteristic CV value Constant Pressure pressure Constant The flow control characteristics of the flow control valves shown in regulating valve flow this catalog are all represented by the flow characteristics graph shown in the figure. In the characteristics table (B), the flow changes substantially when the valve is turned slightly, which makes setting difficult and usage unstable. Therefore, it is necessary to select ser-
vice conditions as close to the status (A) as possible. A KOFLOC manufactures valves individually to ensure they match the 14 service conditions. Simply select the type of valve and specify the supply pressure (primary pressure), outlet pressure (load pressure: 13 secondary pressure), and maximum operating flow rate, and then we 12 will manufacture a flow control valve with the best control character- 11 istics. Even if there is no table or graph like the ones shown here, we 10 can select the best valve. 9 The CV value used as the flow characteristics of needle valves and 8 7 the like is explained below. B The CV value is a kind of flow coefficient, indicating the approximate 6 flow through a valve when a certain pressure is applied. 5 4 P1: Primary-side absolute pressure [MPa·abs] 3 P2: Secondary-side absolute pressure [MPa·abs] 3 2 Q: Flow rate [m /h] Number of revolutions needle ρ: Specific gravity (Gas: Air = 1, Liquid: Water = 1) 1 0 100 200 300 400 500 600 700

コフロック英文カタログ Ｐ 82 1/24 06+ 平山 The CV value of a needle valve changes as shown in the figure when the valve opening changes. Setting aside the control characteristics, the problem is the flow rate, not selection of an actual valve. There- fore, the importance point is the maximum CV value shown in the 10 figure. This catalog shows the maximum CV values of all needle valves. 9 When the maximum CV value is substituted in the aforementioned 8 equation to find Q, the maximum flow rate under the operating pres- sure and temperature conditions is derived. However, application of 7 this method becomes more difficult as the flow becomes more pre- 6 cise, so use it just as a rough standard. Suppose 0.075 is the CV value, for example. Let’s find the flow 5 rate when the primary pressure (gauge pressure) is 0.1 MPa and 4 the secondary pressure in the atmosphere (gauge pressure) is 0 3 MPa in cases where air of 20°C is to be controlled.

コフロック英文カタログ Ｐ 85 1/24 06+ 平山 Precision Needle Valve w/Non-rotary Needle MODEL 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.
Features • Capable of controlling ultra-minute flows Very accurate, stable control of ultra-minute flows up to 1 ml/min possible • Wide variations of needle type 15 types of needles are available for your choice of the type that best suits your needs. • Needle of non-rotary structure Because this valve is constructed so that the rotation of the regu- lating screw is transformed into linear motion of the needle, the valve has a longer life in addition to superior control performance. • Superior temperature characteristic (15-35°C) The valve counts on an outstanding temperature characteristic (flow fluctuations remain within an insignificant range of 0.3%/°C to ambient temperature variations) thanks to the temperature compensation sys- C tem incorporated in the valve's needle and orifice. This temperature compensation system is a utility model of KOFLOC registered at the 2412L 2412T United States Patent and Trademark Office. (Optional specification for needles #SS1 to #3B-BS) This temperature compensation system is applicable to gases only, and not to liquids, because the viscosity of a liquid may fluctuate de- pending upon the temperature conditions.
Applications Example of Use with Model 2412 • For accurate control of minute flows of gases and liquids

コフロック英文カタログ Ｐ 93 1/27 04 石川 Variable Secondary Pressure Flow Controller (Not subject to outlet pressure variations) MODEL 2203 Series
A flow controller is a differential pressure regulator de- signed to control minute gas flows with precision and keep a certain constant flow rate. Model 2203 Variable Second- ary 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 incor- porated precision needle valve without being affected by such fluctuations.
Features • Stable flow control A non-rotary needle valve composed of high-precision components ensures smooth control of minute flows. • Not subject to load pressure fluctuations The incorporated precision needle valve protects flows from being affected by secondary or outlet pressure fluctuations, so the product is a 'must-be' tool in the first stage of any flow control line. • Cleanliness ensured C All the components are super-cleaned before assembly so that the product can be safely used even on instruments for analysis for which cleanliness is essential.
