Electric V type regulating ball valve ZAJV-16C

1、 Product Overview

The electric V regulating ball valve ZAJV-16C is a regulating ball valve developed by Fouten Flow Control (Jiangsu) Co., Ltd. for working conditions containing fibers, particles, and high viscosity media. The valve core adopts the V type opening design, which combines cutting and precise adjustment functions, and can replace some traditional regulating valves for applications such as pulp, powder suspension, papermaking white liquid, coal chemical black water, etc. drive Electric actuator, supporting switch or adjustable control, can be connected to protocols such as 4 to 20mA signals, Modbus, etc.

The valve body and core of ZAJV-16C can be made of materials such as WCB, CF8, CF8M, etc. The valve seat is made of hard alloy or surface hardened treatment to improve erosion resistance and wear resistance. The V type opening exhibits approximately equal percentage flow characteristics during the rotation process of 0° to 90°. It is sensitive to adjustment at small openings and has high flow capacity at large openings, making it suitable for wide range adjustment needs. The electric actuator is equipped with overheat protection and torque limit, ensuring safe and reliable operation.

2、 Structural form and working principle

This valve mainly consists of a valve, V type ball core, valve seat, rod, packing box, and electric actuator. The V blade of the ball core is in contact with the valve to form a sealing surface, and the electric actuator outputs torque to drive the rod to rotate, driving the core to rotate. When the angle between the opening of the V type chip and the flow channel changes, the effective flow area also changes, achieving continuous adjustment of the dielectric mass. When fully open, the flow is approximately straight and the loss is low; When fully closed, the ball core and valve seat form a metal or soft hard composite seal that cuts off reliably.

The valve stem adopts an anti blowout structure design, and the packing box is equipped with a loading type material cover to reduce the risk of external leakage. The connection between the actuator and the valve body complies with the ISO 5211 standard, making it easy to replace the actuator with different brands or specifications. Adjustable configuration with built-in position feedback encoder, capable of outputting 4 to 20mA position signals for easy monitoring of valve opening by the upper computer

3、 Main technical parameters

Public diameter: DN25 to DN500. Pressure level: PN1.6, PN2.5, PN4.0, MPa. Applicable temperature: - 29~200℃ (soft seal; -29~425℃ (hard seal, subject to the seal). Connection type: flange type GB/T 9113HG/T 20592. Leakage level: GB/T 4213 standard IV level (adjustable position); When fully closed, it meets the sealing requirements of GB/T 13927 B level. Traffic characteristics: approximately equal to 100%. Adjustable ratio: 100:1. The flow coefficient Kv varies with the opening angle and diameter of V. When selecting, the maximum/minimum flow and front to back difference should be provided.

Electric actuator power supply: AC220V or AC380V, 50Hz; Optional DC24V. Control signal: 4~20mA adjustable or switch type. Travel time: 15~120 seconds adjustable (depending on the diameter of the actuator torque. Protection level: IP67. Explosion proof level can be selected as Exd II BT4. Valve body material: WCB, CF8, CF8M; The valve core/seat can be welded with Stellite or sprayed with hard alloy.

Four product features

1. V type ball core opening design is not easy to block media containing particles, and has good self-cleaning performance. 2. has both adjustment and cut-off functions, reducing the number of valves on the pipeline. 3. hard seal structure is resistant to erosion and suitable for long-term operation of abrasive media. The 4. electric drive is easy to remotely control and can be integrated with the DCS and SCADA series. 5. actuator torque limit protection to prevent over torque Valve body. The 6. valve seat can be sealed in both directions with minimal restrictions on installation direction (based on the product structure diagram). 7. can be maintained with online filling and vulnerable parts, reducing the difficulty of maintenance.

5、 Applicable working conditions and industries

Suitable for papermaking, coal chemical slurry, sewage treatment sludge, ore, stone, and working media containing solid particles. Can be used for desulfurization slurry regulation in the power industry; Can be used for slurry distribution in the metallurgical industry; In the petrochemical industry, it is possible to regulate the bypass containing catalyst particles. For pure gas or clean liquid operating conditions, the V ball valve can also provide wide range energy-saving adjustment, but the sealing structure needs to be confirmed according to the leakage level requirements

During installation, it should be ensured that the valve body has sufficient space for the ball core 90° to rotate, and attention should be paid to the impact of the actuator height on the pipeline shelf. Adjust the opening calibration of the regulating valve during testing, and confirm that the corresponding positions of 4mA and 20mA are correct. It is recommended to install a filter in front of the valve for regular flushing of media containing particles to extend the lifespan of the valve seat

6、 Selection and ordering instructions

When placing an order, please provide: medium name, solid content and particle size, temperature and pressure, nominal diameter, connection standard, flow rate and pressure difference range control method (on/off), power supply and explosion requirements, and fault location (power-off on/off/hold). Fouten Flow Control Control (Su) Co., Ltd. can calculate the Kv value based on the working parameters and recommend the aperture, providing composition, external dimensions, and electrical wiring diagrams. The product comes with a certificate of conformity, material certification, and integrity upon leaving the factory Verification records.

7、 Maintenance and Precautions

During operation, it is necessary to regularly observe whether the actuator moves smoothly, and whether there are constant noises or excessive torque alarms. The valve seat and ball are worn, and when the medium is highly corrosive, the inspection period should be shortened, and the valve seat component should be replaced if necessary. The grease of the electric actuator gearbox should be replenished or replaced according to the prescribed period. When installing outdoors in winter, insulation or heat should be considered to prevent the medium from freezing and jamming the valve core. Before stopping maintenance, the power supply must be cut off and the pipeline pressure must be released to ensure that it can only be disassembled.
