Honeywell 316203A Valve Assembly

The Honeywell 316203A is a precision-engineered pressure regulator valve assembly designed specifically for integration with Honeywell PP901A and PP902A pneumatic-to-electric transducers. As a critical component for C Series configurations, this assembly ensures stable pressure modulation and consistent signal conversion in complex pneumatic control loops. It is important to note that the 316203A is functionally identical to the 316203A/U universal part number, allowing for direct field replacement without recalibration of the surrounding architecture. This valve assembly is engineered to manage specific air pressure requirements, though it is strictly incompatible with older PP90x Series B units. For technicians performing HVAC pneumatic repairs or Honeywell transducer maintenance, utilizing this OEM assembly is essential for maintaining the linearity and calibration integrity of the pressure-to-current (P/I) interface. Correct installation ensures the pneumatic regulator valve operates within the tight tolerances required for commercial building automation systems.

• Direct OEM Compatibility: Specifically designed for seamless integration with Honeywell PP901A and PP902A C Series transducers.
• Interchangeable Design: Full parity with the 316203A/U cross-reference facilitates streamlined inventory management.
• Pressure Stability: Provides reliable regulation to maintain signal accuracy across the transducer’s operating range.
• C Series Optimization: Engineered to meet the specific flow and pressure drop characteristics of modern Honeywell pneumatic architectures.

Is the 316203A compatible with PP901B or PP902B models?
No, this valve assembly is exclusively for C Series transducers and cannot be used on any PP90x Series B hardware due to internal design variations.

Does this part replace the 316203A/U?
Yes, the 316203A and the 316203A/U are the same physical component; the /U suffix simply denotes a universally packaged version of the same engineering specification.

What are the symptoms of a failing pressure regulator valve in this series?
Field failures typically manifest as drifting output signals, inability to hold a setpoint, or audible air leaks at the transducer interface, necessitating a replacement Honeywell valve assembly.
