PRECISE 4-20mA CONTROL OF AIR ACTUATED VALVES
FOR CUSTOMIZABLE FLOW RATES
• Uses force balance principle of operation and 4-20mA electronic signal for precise control of air actuated ball valves.
• Combine with Series ZC characterized or custom-profile ball valves for exact flow rate control.
• Compact, corrosion-resistant design.
• Complete calibration without removing cover.
• Large, clear position indicator.
• Repeatability <0.5% f.s. with hysteresis <0.6 f.s.
