Electric Control Valve for Water Steam Oil ISO Certified

The electronic electric sleeve control valve consists of a straight-stroke fully electronic electric actuator and a straight-through low-flow-resistance balanced sleeve valve. It features a compact structure, light weight, and sensitive action.

The fluid channel is in an S-shaped streamline design, resulting in small pressure drop loss, large valve capacity, and precise flow characteristics. It can be controlled and operated directly by accepting control signals from regulating instruments (such as 4-20mA DC, 0-10mA DC, or 1-5V DC) and single-phase power supply, realizing automatic regulation and control of fluid media in process pipelines.

Widely used in precisely controlling process parameters of media such as gas, liquid, and steam, maintaining parameters like pressure, flow rate, temperature, and liquid level at the set values. It is a new generation of general-purpose control valve products conforming to IEC standards.

• The ZDLM electronic electric sleeve control valve is an actuator unit of instruments in automatic control systems. It is powered by an AC220V power supply and can be controlled and operated by accepting current or voltage signals (4-20mA, 0-10mA, or 1-5VDC) input from DCS, PLC systems, regulating instruments, operators, etc.
• Adopts an electromechanical integrated structure, with functions such as in-machine servo operation, opening signal position feedback, position indication, and manual operation.
• Features strong functionality, reliable performance, simple wiring, and high regulation accuracy.
• Changes the valve opening displacement through the thrust output by straight stroke to achieve precise regulation and control of the process parameters of fluid media.
• Can be classified by action mode: Direct action (Electrically closed - normally open type) or Reverse action (Electrically open - normally closed type).
• Straight-through sleeve cast spherical valve with balanced valve core, featuring small unbalanced force and stable operation.
• Suitable for working occasions with large pressure difference between the front and rear of the valve and slightly large leakage.
