Raypak 007222F Relief Valve

The Raypak 007222F Relief Valve is a 3/4" NPT precision-engineered safety component designed for high-capacity hydronic heating and commercial boiler applications. Rated for a 60 PSI set pressure and a massive 1,100,000 BTU discharge capacity, this pressure relief valve (PRV) is critical for protecting heat exchangers and system piping from over-pressurization. Constructed with a rugged brass body and a corrosion-resistant stainless steel spring, it utilizes a Noryl diaphragm to ensure consistent lift and reseating performance even in demanding industrial environments.

As a veteran tech knows, matching the BTU rating and PSIG to the manufacturer’s MAWP (Maximum Allowable Working Pressure) is non-negotiable for system safety. The 007222F is a genuine OEM Raypak replacement part, ensuring exact fitment for Hi Delta, Xtherm, and legacy Raypak commercial heaters. Whether you are performing a seasonal teardown or responding to a fast-cycling boiler, this ASME-rated relief valve provides the reliable thermal expansion protection required to prevent catastrophic equipment failure and minimize system downtime.

• High Thermal Capacity: Rated for up to 1,100,000 BTU/hr, making it suitable for large-scale commercial water heaters and boilers.
• Industrial Grade Materials: Features a heavy-duty brass body and stainless steel spring for maximum durability against mineral buildup and corrosion.
• Precision Safety: Maintains system integrity by discharging excess pressure at a factory-set 60# (PSI) threshold.
• Direct Compatibility: Designed specifically for Raypak pool heaters and hydronic boilers, eliminating the risks associated with generic third-party valves.

Can I use this 60 PSI valve on a system rated for 30 PSI?
No. A relief valve must be rated at or below the MAWP of the vessel it protects. Using a 60 PSI valve on a 30 PSI system creates a dangerous over-pressure condition by preventing the valve from activating when needed.

Why is my new relief valve simmering or leaking?
"Simmering" often occurs if the system operating pressure is within 10% of the 60 PSI set point. If it leaks at lower pressures, check for debris on the seat or verify that the expansion tank is not waterlogged, causing rapid pressure spikes.

Is this valve suitable for steam applications?
The Raypak 007222F is engineered for water-based HVACR and hydronic heating systems. Always verify the specific media and temperature ratings against your application’s requirements before installation.
