Brief: Observe the step-by-step operation and see practical examples of usage for the Stainless Steel Explosion-Proof Single Seat Electric Intelligent Proportional Flow Control Valve. This video demonstrates how the ZDLM electronic electric sleeve regulating valve receives control signals to automatically regulate pressure, flow, temperature, and liquid level in industrial processes. Watch a detailed walkthrough of its S-shaped fluid channel, low flow resistance design, and explosion-proof features in various application environments.
Related Product Features:
  • Directly receives 4-20mA, 0-10mA, or 1-5VDC control signals from instruments for automatic regulation.
  • Features a balanced sleeve valve core with very low unbalanced force for stable operation under high pressure differences.
  • Available in both normally open (electric close) and normally closed (electric open) operating modes.
  • S-shaped fluid channel design ensures minimal pressure drop loss and large valve capacity.
  • Precise flow characteristics with linear or equal percentage options for accurate process control.
  • Constructed from stainless steel with explosion-proof capabilities for hazardous industrial environments.
  • Wide operating temperature range from -60°C to 450°C suitable for various media including steam.
  • Compact, lightweight design with sensitive action and multiple nominal diameters from DN20 to DN300.
FAQs:
  • What control signals does this electric control valve accept?
    The valve directly receives standard control signals including 4-20mA DC, 0-10mA DC, or 1-5V DC from regulating instruments, DCS, or PLC systems for automatic operation.
  • What are the available flow characteristics for this control valve?
    The valve offers both linear and equal percentage flow characteristics, achieved through precisely machined valve core window shapes, with an inherent tunable ratio of 50:1 for precise control.
  • In what industrial applications is this control valve commonly used?
    This valve is widely used in chemical, petroleum, metallurgy, power plants, textiles, papermaking, and pharmaceutical industries for automating pressure, flow rate, temperature, and liquid level control of gas, liquid, and steam media.
  • What is the leakage rate specification for this single seat control valve?
    The single seat configuration offers hard seal leakage rate of Grade IV or soft seal leakage rate of Grade VI, providing reliable sealing performance for different application requirements.
