Quotation for electronic electric control valve

The ZDLP electronic electric single seat regulating valve is composed of a straight stroke fully electronic electric actuator and a top guide through low flow resistance single seat valve It has a compact structure, light weight, sensitive action, S-shaped fluid channel, small pressure drop loss, large valve capacity, and flow characteristics. It 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 medium

Structural characteristics of ZDLP electronic electric single seat regulating valve:

1. The ZDLP electronic electric single seat regulating valve is the execution unit of an instrument in an automation control system. It is powered by an AC220V power supply voltage and receives (4-20mA, 0-10mA, or 1-5VDC) current or voltage signals from DCS, PLC systems, regulating instruments, operators, and other inputs to control its operation. It uses fully electronic electric actuators such as 381L or PSL, and has functions such as internal servo operation, opening signal position feedback, position indication, manual operation, etc. It is designed with a mechanical and electrical integration structure, strong functions, * * *, simple wiring, high adjustment accuracy, and can change the valve opening displacement with the thrust output of the straight path to achieve process parameter adjustment and control of the fluid medium

2. ZDLP electronic electric single seat regulating valve can be divided according to its operating mode; Positive effect: electrically closed normally open type (when the electrical signal increases, the valve position shifts downward), "Type B" Reaction effect: electrically open normally closed type (when the electrical signal increases, the valve position shifts upward), "Type K"

3. The ZDLP electronic electric single seat regulating valve is a straight through single seat cast spherical valve with a single seat plunger type valve core, suitable for working conditions with strict leakage requirements, small pressure difference before and after the valve, and medium with certain viscosity or fiber impurities

4. The straight through low flow resistance single seat adopts a bottomless cover top guide structure, which only has one valve seat and one plunger shaped valve core. It has good sealing performance, small leakage, sensitive action, S-shaped fluid channel, small pressure drop loss, large valve capacity, flow characteristics * * *, large adjustable ratio, large guiding area of the valve core guiding part, and strong anti vibration performance. It is suitable for occasions with strict requirements for medium leakage and adjustment accuracy. However, due to the valve structure, the unbalanced force on the valve stem is relatively large, especially under the condition of large nominal diameter, which is more obvious. Therefore, this valve is only suitable for occasions with small working pressure difference
