Capacity Charts for Gas Pressure Regulators. The capacity of any regulator is not an absolute value, but will vary with the application depending on the prevailing differential. We hope the following charts will help you in your selection of a properly sized regulator.
Common inlet connections include POL (Prest-O-Lite), QCC1 or Type 1 (used for most 20-pound tanks), and CGA 510 or CGA 300 (used for 100-pound tanks and larger). Outlet connections may include 3/8-inch or 1/2-inch NPT (National Pipe Thread) or flare fittings.
According to the publication NFPA58, a tank with 20 pounds of gas at 70°F has a pressure of 145 psi, at 90°F would have 180 psi, at 105°F would have 235 psi, and at 130°F would have 315 psi.
Propane regulators serve as a pressure and gas flow regulating device adjusting gas flow for downstream demand. LP Gas regulators vary in size, function and pressure regulating ranges.
29 cze 2022 · Here at Gas Equipment Direct, our aim is to make it as easy as possible for our customers to find the exact regulator they require. We offer several low-pressure regulators including Propane regulators, Butane regulators, Handwheel Propane regulators and Camping Gas regulators.
ANSI Z21.80/CSA 6.22 is the standard for line pressure regulators, suitable for application in natural, manufactured, mixed gases, liquefied petroleum gases and LP gas-air mixture piping systems. Maxitrol, in compliance with ANSI Z21.80/CSA 6.22, offers line pressure regulators for 2 psi piping systems and piping systems up to 5 psi.
Multiple cylinders or tanks may be manifolded to give the required vaporization capacity. Withdrawal of gas from one or two containers can lower the container pressure substantially due to the refrigeration of the vaporization gas. Regulator capacity is then reduced because of the lower inlet pressure. Where any
