KOSO EPA804-L10 Valve Positioner
Product Introduction
The KOSO EPA804-L10 Valve Positioner is a precision device designed for pneumatic actuator-operated control valves, converting a 4–20 mA DC input signal to air pressure for accurate valve positioning. With a maximum supply pressure of 120 psi (800 kPa), it ensures reliable operation in industrial processes. The positioner utilizes mechanical feedback from the valve stem to maintain precise alignment, making it ideal for both straight and angle travel valve applications.
Product Features
