Fisher Types R622E and R652E | High-Performance 2-PSI Service Regulators

The Fisher Types R622E and R652E are Underwriters Laboratories (UL) listed regulators specifically engineered for 2-PSI LP-Gas systems. These units act as the intermediate stage in a multi-stage regulation system, typically installed downstream of a first-stage regulator. They reduce a 10 psig (0.69 bar) inlet pressure down to a steady 2 psig (0.14 bar) outlet pressure. This configuration is ideal for modern domestic applications where 2 psig gas is piped to a final line regulator located inside the building, allowing for smaller piping runs and improved system efficiency.

Key Benefits and Advantages

  • Easy Identification: Both the R622E and R652E feature distinct white closing caps. This industry-standard color-coding allows gas technicians to immediately identify the unit as a 2-PSI regulator during field inspections.

  • 20-Year Recommended Replacement Life: Manufactured with premium materials and advanced coatings, these regulators are designed for a two-decade service life. This longevity reduces long-term maintenance costs for homeowners and utility providers.

  • Superior Relief Performance: Equipped with a high-capacity internal relief valve, these regulators offer exceptional overpressure protection. In the event of a seat failure, the internal relief mechanism prevents dangerous pressure levels from entering the building’s gas lines.

  • Test Ports for Easy System Checks: Integrated 1/8-inch NPT test ports allow for rapid pressure verification. Technicians can perform system diagnostics and leak tests without disconnecting any piping, significantly speeding up the maintenance process.

  • Improved Regulation Accuracy: The internal geometry and spring design provide precise pressure control, ensuring that the downstream line regulator receives a consistent 2 psig supply regardless of the load demand.

  • Corrosion-Resistant Materials: Built with powder-coated aluminum and high-quality internal components, these regulators are designed to withstand harsh outdoor environments and resist atmospheric degradation.

  • Inlet Screen and Positive Drainage: An integrated inlet screen protects the valve seat from pipe scale and debris, while the spring case design ensures positive drainage of moisture and condensation to prevent internal icing.

  • UL Listed: Full compliance with UL standards ensures that these regulators meet the highest safety and performance requirements for the propane industry.

Field of Application

The R622E and R652E are the standard choice for modern 2-PSI propane systems in residential and light commercial settings.

Primary Industries and Uses:
  • Residential Propane Systems: Enabling the use of 2-PSI interior piping systems for home heating and appliances.

  • Light Commercial Gas Delivery: Providing stable intermediate pressure for small businesses and retail spaces.

  • Multi-Stage Gas Sets: Used in tandem with Fisher first-stage and line regulators to create a complete, high-efficiency gas distribution network.

  • Long Pipe Runs: Ideal for installations where the gas tank is located a significant distance from the building, as the 2-PSI pressure reduces pressure drop issues compared to low-pressure systems.
