Key Benefits and Advantages
-
Superior Relief Performance: The R622H exceeds UL requirements for overpressure protection. In the event of a primary seat failure, the internal relief valve limits the downstream pressure to 2 psig or less, which is significantly lower than the industry standard requirements for first-stage safety.
-
20-Year Recommended Replacement Life: Constructed with high-grade materials and a design that emphasizes longevity, the R622H is recommended for 20 years of continuous service, reducing the total cost of ownership for gas utilities.
-
Corrosion-Resistant Construction: The regulator features a durable powder-coated finish and stainless steel internal components to resist the harsh environmental conditions common in outdoor propane tank installations.
-
Easy Installation and Maintenance: The compact design and 1/4 inch NPT gauge taps allow for quick installation and easy pressure verification. The simple mechanical design ensures that routine inspections are straightforward for field technicians.
-
Positive Drainage: The spring case is designed with a drip-lip vent that ensures moisture and condensation drain away from the internal spring and diaphragm, preventing ice build-up in cold climates.
-
High Capacity: Capable of supporting large domestic or light commercial loads, ensuring stable intermediate pressure even during periods of peak gas demand.
-
Visual Identification: The regulator features a bright red spring case, which is the industry-standard color for high-pressure first-stage regulators, allowing for quick visual identification during site audits.

Field of Application
The R622H is the essential first step in a high-quality propane distribution system. It is found wherever high-pressure tank storage must be safely transitioned to intermediate distribution piping.
Primary Industries and Uses:
-
Residential Propane Systems: Acting as the tank-mounted regulator in a two-stage home heating system.
-
Commercial Gas Service: Managing high-pressure headers for restaurants, laundromats, and small businesses.
-
Agricultural Heating: Providing reliable gas pressure for livestock heaters and grain drying equipment.
-
Multi-Tank Manifolds: Balancing pressure across multiple cylinders in large storage arrays.
