ตัวแทนจำหน่าย Fisher by Emerson Type R622H First Stage Regulators ในประเทศไทย
The Fisher Type R622H is a UL®-listed regulator specifically engineered for two-stage LP-Gas systems. This regulator reduces tank pressure to a steady 10 psig (0.69 bar). Designed with a compact and durable structure, it features screened drip-lip vents oriented over the outlet as standard for reliable outdoor performance.
Features
• 20-Year Recommended Replacement Life
Built with robust, time-tested engineering and enhanced corrosion-resistant materials inside and out, the Type R622H is designed to deliver long-term durability. When properly installed and maintained, it offers a recommended 20-year service life—though in some harsh environments, earlier replacement may be necessary.
Stable and Accurate Regulation
• The regulator includes Fisher’s signature large molded, fabric-reinforced diaphragm combined with a spring-assisted vent stabilizer to ensure precise and consistent pressure control under varying conditions.
Exceptional Overpressure Protection
• A high-capacity relief valve and generously sized vent work together to provide overpressure protection that exceeds UL safety standards. When used in tandem with a Type R622 or R652 second-stage regulator, the system limits downstream pressure to 2 psig (0.14 bar)—even in the event of a double failure.
Easy System Monitoring
• Equipped with 1/8-inch NPT inlet and outlet gauge taps, orificed to a number 54 drill size, for quick and convenient pressure checks during setup or routine inspection.
Advanced Corrosion Resistance
• All castings are treated with internal and external coatings before painting to resist rust and degradation. Critical components, such as the relief valve spring and retainer, are made of stainless steel, and the relief valve seat is crafted from non-corrosive materials.
Positive Drainage Design
• When installed with the spring case oriented downward, the internal design facilitates moisture drainage—preventing corrosion and freezing within the spring chamber, ensuring long-lasting and trouble-free operation.
