Dynamic Balance Electric Control Valve

DZLM dynamic equilibrium electric control valve is electrically adjustable dynamic equilibrium with the integration of products, mainly used in air-conditioning system at the end of HVAC equipment (such as air tank, new air handling units, air handler) temperature control, by configuring the intelligent module control device, easy on each loop flow, the temperature is automatically controlled to achieve rational use of energy, energy saving, intelligent management. This valve terminal equipment apply only influence affected the standard control signals, regardless of system pressure fluctuations, the system adjustment is more stable, more energy-efficient, especially for large changes in system load variable flow systems. Advantages: 1. Stable: Flow terminal equipment is not affected by changes in system pressure fluctuations, flow changes do not interfere with each other. 2. Energy: energy saving compared with traditional systems 6-20%. 3. Efficient: greatly reducing the debugging time, the system has a high efficiency. 4. Comfort: temperature regulation more precise, more comfortable than the traditional variable flow systems. Material and Life: 1. Body: high quality gray iron 2. Trim: brass, stainless steel 3. Spring: Stainless steel 4. Diaphragm: EPDM buried fiber 5. life: more than ten years Features: 1. Drive straight trip, good interchangeability. 2. The flow curve: linear / equal percentage flow error 3. <= 5% 4. Working temperature: 0--150 ℃ Control: 1. Intelligent regulated (most common) 2. proportional-integral type Optional: ML7421B1023 Honeywell drive SQX Siemens drive standard domestic Drive Technical parameters: VA-3000 and VA-7000 are available in two basic models VA-7100 (VA-3100) reversible motor running to provide incremental control. VA-7102 (VA-3102) or 4-20MA can accept input 0-10V DC control signals, providing proportional control, with output feedback 0-10V or 4-20mA.
