主なメリットと利点
-
Improved Accuracy: The R222 Series is engineered to provide precise pressure control, ensuring that domestic appliances receive a consistent flow of gas even as demand fluctuates.
-
Superior Relief Performance: Equipped with a high-capacity internal relief valve, the R222 Series offers overpressure protection that exceeds UL standards, safely venting gas to prevent dangerous pressure spikes in the home.
-
20-Year Recommended Replacement Life: Built for long-term durability, these regulators utilize high-quality materials and coatings that allow for two decades of reliable service.
-
Corrosion-Resistant Materials: Every unit is constructed to withstand outdoor exposure. The use of robust alloys and protective finishes ensures the regulator remains functional in humid or coastal environments.
-
Positive Drainage Design: The spring case is designed to shed water and condensation effectively through a screened drip-lip vent. In the standard configuration, this vent is oriented over the inlet to ensure any moisture drains away from critical internal components.
-
Inlet Screen: A built-in stainless steel inlet screen protects the valve seat and orifice from scales, shavings, or debris that may be present in the piping, reducing the risk of seat leakage.
-
Integrated Test Ports: Features accessible test ports that allow technicians to perform system pressure checks and leak tests quickly and accurately without disconnecting the regulator.
-
Visual Identification: The R222 Series is painted palm green, the industry-standard color for second-stage low-pressure regulators, allowing for instant identification during site inspections.
技術的特性
-
Inlet Pressure Range: Optimized for 10 psig (0.69 bar) from a first-stage regulator.
-
Outlet Pressure Setting: Factory set at 11 inches w.c. (27 mbar).
-
Certification: Underwriters Laboratories (UL) listed for LP-Gas service.
-
Connection Sizes: Available in standard NPT threaded connections for seamless integration into residential gas plumbing.
-
Venting: Screened drip-lip vent to prevent blockage by insects or debris.
-
Body Material: Durable, lightweight aluminum.
適用分野
The R222 Series is a vital component for safe gas delivery in residential environments. Its small size and high reliability make it a standard choice for propane marketers and installers.
