Product Description
The 43AP-FA42C-PC is a heavy-duty pneumatic indicating controller designed for accurate process regulation in environments where electronic instrumentation is impractical, unreliable, or prohibited. Utilizing a bellows-type pressure receiver (PC element), the controller converts process pressure into precise pneumatic control action without reliance on electrical power.
Configured with Proportional plus Integral (PI) control, the 43AP-FA42C-PC effectively eliminates steady-state offset, delivering stable and repeatable control across a wide range of industrial applications. Its robust mechanical design and corrosion-resistant enclosure make it especially suitable for harsh outdoor and hazardous-area installations.
A key feature is the built-in bumpless Auto/Manual transfer station, allowing operators to change control modes without disturbing the process. The integrated balance gauge and manual regulator ensure smooth transitions and reliable field operation in critical pneumatic loops.

Marine, offshore, and explosive-area installations
Technical FAQ
Q: What is the advantage of the “PC” bellows input element?
A: The PC pressure receiver bellows provides high sensitivity and excellent repeatability, enabling direct interfacing with pneumatic transmitters or pressure sources while maintaining stable control output.
Q: How does the bumpless transfer function operate?
A: The Type C transfer station includes a manual regulator and balance gauge. Before switching from Auto to Manual, the operator adjusts the manual output until the balance gauge reads zero. This ensures the output signal remains unchanged during transfer, preventing valve movement or process upset.
