Product Overview
The PARKER P3HPA12AS2AD1A is a high-precision pneumatic pressure regulator from Parker’s P3H series, engineered for accurate downstream pressure control in compressed air and neutral gas systems. As a direct-operated, diaphragm-sensing regulator, it modulates a poppet-style control element to maintain a stable secondary pressure regardless of fluctuations in inlet pressure or flow demand. The unit is designed for panel or line mounting within pneumatic control circuits, serving as a critical interface between plant air supply and sensitive downstream actuators, instrumentation, and process equipment. Its balanced valve design and precision adjustment mechanism make it suitable for applications requiring repeatable pressure setting and minimal drift over extended duty cycles.
