Product Overview
Valve Positioner is an important accessory for pneumatic control valve assemblies. It helps control the actuator movement based on the input signal from the control system, allowing more accurate valve opening and stable flow, pressure, or process regulation.
Based on the product label, the sample model shown is YT-1000LDM. The unit is an electro-pneumatic positioner with 4–20 mA DC input signal, explosion-proof construction, -20 to 70°C ambient temperature range, and 1.4–7 kgf/cm² supply pressure. The product is also equipped with a pressure gauge for easier air pressure monitoring.
