Maxitrol KVOP-4 Vent Dampener
If you are dealing with a surging regulator on a high-flow setup, the Maxitrol KVOP-4 Vent Dampener is the specific field fix required for the 325-7A, 325-7AL, 325-9, and 325-9L series line pressure regulators. As a veteran HVAC technician knows, heavy-duty regulators can experience hunting or oscillation during rapid load changes; this venting accessory acts as a pneumatic snubber to stabilize the diaphragm response without sacrificing lock-up performance. Precision-engineered for gas pressure regulation systems, it threads directly into the vent port to provide a controlled orifice, ensuring even flow across industrial and commercial HVACR applications. By optimizing the atmospheric pressure balance within the upper diaphragm chamber, the KVOP-4 eliminates the typical chattering often found in Maxitrol 325 series installations. This genuine Maxitrol part is essential for maintaining ANSI Z21.80 compliance in indoor installations where precise air control and safety are non-negotiable for gas contractors.
- Stabilizes Diaphragm Oscillation: Effectively eliminates regulator hunting and surging during high-demand cycles.
- Direct Compatibility: Engineered specifically for 325-7 and 325-9 series Maxitrol regulators.
- Improves Combustion Efficiency: Maintains consistent delivery pressure to downstream equipment by smoothing out air entry.
- Durable Construction: Built to withstand the rigors of mechanical rooms and industrial environments.
- Easy Thread-In Installation: Minimizes downtime for service technicians troubleshooting unstable gas lines.
How does this assist with regulator surging?
The KVOP-4 functions as a restrictor that dampens the rate at which air enters and exits the atmospheric side of the diaphragm, preventing the rapid "hunting" movement that causes pressure fluctuations.
Is this a vent limiting device?
No, this is a vent dampener. While it controls the speed of the diaphragm, it does not replace a vent limiter intended to restrict gas escapement in the event of a diaphragm rupture. Always consult your local codes regarding piping to the outdoors.
Can I use this on a 325-3 or 325-5 series?
No, this specific model is sized and calibrated for the higher capacities and port sizes of the 325-7A and 325-9 series frames. Using the wrong dampener can lead to sluggish regulator response.
