The CL31 regulator can produce substantial savings for users in lower initial costs, lower installation costs and lower maintenance costs. Optimum valve design limits over boosting or rapid drop-off as the capacity requirement changes, including fast on-off loads. The CL31 was designed for systems requiring highly accurate pressure regulation such as: utility Fixed Factor metering of relatively small loads (up to 4000scfh)and industrial heating equipment requiring constant high burner pressures (1 PSIG to 20 PSIG).
