FISHER R622-CFF SECOND STG LP REG
Product Details
Attributes
Features
Fisher Regulator, 1/2 x 3/4 in Nominal, FNPT Connection, Propane Gas Media, 2 Stages
The type R622 second-stage regulators are underwriters laboratories listed regulators designed for two-stage LP-gas systems. These units are designed to reduce the outlet pressure from a first-stage regulator (usually 10 lbf/sq-in) to 11 in water column. The R622 incorporates the standard straight-though flow design while the R652 is designed for back-mount installations. Both have screened drip-lip vents are oriented over the inlet as standard.
- 20 years recommended replacement life-the R622 are designed using rugged time proven design concepts and constructed of corrosion-resistant materials, both internally and externally
- Improved regulation-Fisher's large fabric reinforced diaphragm and spring assisted vent stabilizer deliver accurate and stable regulation
- Over-pressure protection-the combination of a high capacity relief valve and large vent provide overpressure protection which exceeds UL standards by limiting the downstream pressure to 2 psi even in a double failure situation when used with a R622H
- Inlet screen-fisher stainless steel inlet screen reduce the amount of debris that can enter the regulator
- Gauge taps-built-in 1/8 in NPT gauge taps orificed to a number 54 drill size on upstream and downstream for easy gas system check
- 11 in WC outlet adjustment setting
- With proper installation and periodic inspection and maintenance the R622 design will meet a 20 year recommended replacement life
- 1400000 Btu/hr nominal capacity
