6 Product 3: CV3000 series Top-Guided Single-Seated Control Valves

7 Type: Globe Size: 1/2'' - 4 (DN15 DN100) Pressure Rating: ANSI 150 ~ ANSI 300 (PN16~PN64, JIS10K~JIS30K) Body Material: Carbon steel, Stainless steel, Alloy steel Operation: Pneumatic diaphragm actuator, Pneumatic piston actuator, Electric actuator The CV3000 series range of Top-guided Single-seat Control Valves features a compact valve body with excellent flow control and minimal pressure loss. CV3000 valves have large Cv values, high range ability, and accurate flow control performance. When securely held in place by a top-guided stem with a long stroke, the valve plug is highly resistant against vibration and provides flow shutoff performance that fully satisfies IEC standards. The valve also features a compact but powerful multi-spring actuator. Model CV3000 series control valves are especially suitable for process control applications where high reliability and tight flow shutoff are essential. 1. Selection of CV3000 series specifications Selection of control valves has traditionally required knowledge and experience. However, CV3000 series offers you more accurate product specifications, so that you can easily pinpoint the control valve that satisfies fluid specifications (such as flow rate, pressure and temperature) at your plant and provides the functions that you need. (To start your process of selecting specifications, open the Model Selection on page 26 and 29, and follow the instructions on the selection map in Figure 1.) If you do not find a valve that completely satisfies your requirements, Please just free to contact the VALTORQUE for assistance. 2. Basic model numbers Basic model: 1/2 to 4 inches Model AGVB: JIS 10K, ANSI 150, JPI 150 Model AGVM: JIS 16K, JIS 20K, JIS 30K, ANSI 300, JPI Optional specifications 3-1 Body Figure 2 shows optional specifications of the body.

8 Figure Nominal sizes VALTORQUE manufactures diameters from 1/2 inch (15 mm) to 4 inches (100 mm) Port size and flow control characteristics The selection of the port size and the rated Cv value falls within the scope of Table 1 according to the Nominal size. For nominal sizes 1inch (25 mm) or less, port sizes are expressed in terms of Cv values. Flow control characteristics depend on the rated Cv value, be set to linear model or equal percentage model. Based on the rated Cv value and the calculated necessary Cv value, check the controllability (valve position) using the flow control characteristics Tables in Figure 4, 5, and Pressure rating and end connection (flange type) We manufacture RF: JIS 10K, 16K, 20K, 30K (JIS B ), ANSI 150, 300 (ASME/ANSI B ), JPI 150, 300 (JPI-7S ) Option: Socket weld, butt weld For other rated pressures and connection types, you are recommended to consider the CV 3000 series of control valves.

9 3-1-4 Bonnet style We manufacture bonnets that can be used at fluid temperatures ranging from -196 C to 400 C Body, plug and seat ring materials For combinations of body, plug and seat ring materials and their applicable temperature ranges, see Table 7. In some ranges the plug seat ring material needs hardening treatment. See Figure 9. When you select a soft seat, refer to Figure Valve seat leakage For the seat leak performance when the valve is fully closed, select from among the following four classifications, which conform to IEC :1999 and JIS B :2008 : Class IV: 10-4 rated Cv value (0.01% of rated Cv value) Class IV-S1: X rated Cv value (0.0005% of rated Cv value) Class V: Valve differential pressure (MPa) Port size (mm) l/h Class VI:3 valve differential pressure (MPa) leakage coefficient ml/min. shown below VALTORQUE is one of the lead manufacturing globe control valves, including single seated globe control valve automated with pneumatic diaphragm actuator/spring return, globe control valve automated with pneumatic double acting actuator, single seated control valve automated with electric actuator.
