instructions
The EP3000 electric pneumatic valve positioner is based on internationally advanced foreign products of the same type. It is used in conjunction with a regulating valve to form a closed-loop control circuit, converting the electrical signal output by the regulator into a pneumatic signal that drives the regulating valve. At the same time, it provides position feedback based on the opening of the regulating valve to enable precise positioning of the regulating valve.
Product Features
1. Suitable for small and large capacity actuators.
2. The amplifier has low gas consumption, large capacity, high aerodynamic power, good stability, and high sensitivity.
3. Easy to calibrate and convenient to install.
4. Has good composite explosion-proof function.
5. There is a special constant orifice needle, which facilitates the removal of the through-hole and keeps the working air path unobstructed.
