Type R622 Pressure Reducing Regulator - First Stage Regulator

Type R622 direct-operated, spring-loaded regulators provide economical pressure reducing control in a variety of residential, commercial, and industrial applications. These regulators can be used with natural, manufactured, or liquefied petroleum gases and have the same inlet and outlet pressure capabilities.

Features

• Compact design
• High capacity
• Protective inlet screen
• Internal relief
• Light weight
• Inlet and out pressure gauge taps

Maximum Inlet Pressure

• Operating: 125 psig (8.62 bar)
• Emergency: 125 psig (8,62 bar)
• Except 1.8 to 2.2-inches w.c.(4 to 5 mbar) spring range which has operating and emergency pressures of 60 psig (4,14 bar)

Maximum Outlet (Casing) Pressure

• Operating to Avoid Internal Part Damage: 3 psid (0,21 bar d) above outlet pressure setting
• Emergency: 20 psi (1,38 bar

Time proven design constructed of corrosionresistant and wear-resistant materials, the R622H is designed to provide a Recommended Replacement Life of 20 years. Built-in 1/8” FNPT gauge taps on both the inlet and outlet pressure sides allow for easy system checks. A large 3/4” FNPT drip-lip vent reduces the chance of blockage by freezing rain or sleet when properly installed with the vent pointing down. Each R622H is equipped for overpressure protection with a corrosion-resistant internal relief valve that provides high capacity relief and a travel stop on the closing cap. Its size and con.guration make it ideal for under-the-dome installations.

First-Stage regulators reduce tank pressure to a lower pressure (usually 10 psig or 0,69 bar) for a Second-Stage regulator. Fisher First-Stage regulators are painted red for easy identi.cation. Vents are screened with standard orientation over the outlet.
