EPC1000 electro-pneumatic valve positioner

EPC1000 series of electrical converter is a new type of structure of the electrical conversion unit, which can be different input current signal is converted to the corresponding output pneumatic signal. The converter has a pneumatic power amplifier inside, you can get a higher output power of pneumatic signals to a variety of pneumatic actuators to improve the operating speed of the actuator.
