Highlight: Electric control valve, stainless steel intelligent steam temperature proportional flow cast steel single seat explosion-proof control valve

Product introduction:

The ZDLM electronic electric sleeve regulating valve is composed of a straight stroke fully electronic electric actuator and a straight through low flow resistance balanced sleeve valve It has a compact structure, light weight, sensitive action, S-shaped fluid channel, small pressure drop loss, large valve capacity, precise flow characteristics, and can directly receive control signals from regulating instruments (4-20mA DC 0-10mA DC or 1-5V DC) and single-phase power supply to control operation, achieving automatic regulation and control of process pipeline fluid media. It is widely used for precise control of process parameters such as pressure, flow rate, temperature, liquid level, etc. of gas, liquid, steam and other media to maintain them at given values It is a new generation of universal regulating valve products that comply with IEC standards.

Product features:

1. ZDLM electronic electric sleeve regulating valve is the execution unit of the instrument in the automation control system. It is powered by AC220V power supply voltage and receives current or voltage signals (4-20mA, 0-10mA or 1-5VDC) from DCS, PLC system or regulating instruments, operators, etc. to control the operation. It adopts an electromechanical integrated structure and has functions such as internal servo operation and position feedback of opening signal, position indication, manual operation, etc. It has strong functions, reliable performance, simple wiring, high adjustment accuracy, and can change the valve opening displacement with the thrust output of straight stroke, achieving precise adjustment and control of process parameters of fluid medium
2. ZDLM electronic electric sleeve regulating valve can be divided according to its operating mode;
Positive effect: Electric closed normally open type (when the electrical signal increases, the valve position shifts downward), Type B
Reaction: Electric open normally closed type (when the electrical signal increases, the valve position shifts upward), K-type
3. The ZDLM electronic electric sleeve regulating valve is a straight through sleeve cast spherical valve with a balanced valve core, which has low unbalanced force and stable operation. It is suitable for working environments with large pressure difference and slightly large leakage before and after the valve
4. The straight through low flow resistance sleeve valve adopts a pressure balance cage valve core structure. The valve core is cylindrical, and a certain characteristic window hole is precisely machined. It is guided by the inner circle and top of the sleeve, so the unbalanced force on the valve stem is very small, the operation is stable, and the performance is good. It is a force balance type regulating valve Suitable for situations where the pressure difference between the front and rear ends of the valve is high. Due to the side guidance of the sleeve on the valve core, the vibration caused by vortex impact is reduced, resulting in low noise, small cavitation flash evaporation effect, and long service life But the leakage rate of the valve seat is slightly higher than that of a single seat valve
5. By changing the design of the valve core shape; Different valve core window shapes will result in different flow characteristic values: equi percentage (logarithmic), linear
This series of products is widely used in the automation and remote control of industrial production processes such as chemical, petroleum, metallurgy, power plants, textiles, papermaking, and pharmaceuticals
