Type R622 Pressure Reducing Regulator - Second 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.

Stage regulators, are Underwriter’s Laboratories (UL) Listed Regulators designed to reduce the outlet pressure from a First- Stage regulator, usually 10 psig (0,69 bar) to 11” water column (27 mbar), in domestic installations. Vents are screened with standard orientation over the inlet, but other orientations are available. Fisher Second-Stage regulators are painted palm green for easy identification.
