210J, Inlet 10 psi, 50,000 CFH The 210J models are of cast aluminum and steel construction with 125 lb flange connections. Internal parts are cast or machined from corrosion resistant metals or are electroplated. Diaphragms are of the finest quality synthetic coated fabrics. 210J regulators are painted providing a protective coating if used out-of-doors. The 210 series has been designed for maximum control functions in an easy-to-use package. For gas-fired boilers, steam generators, industrial furnaces, ovens and similar high demand equipment. Balanced valve design eliminates the inlet pressure effect acting on the valve. Regulating stability is improved and hunting tendencies reduced by the use of dampening mechanisms in both the breather outlet and sensing tube. You get precise regulation over a broad range of pressures and flow rates with a Maxitrol 210, including "zero governor" application. 210 series industrial regulators are intended for use with all fuel gases. Ambient temperature limits are -40°F to 200°F. Maximum emergency exposure pressure is 25 psi. At this pressure, the regulator will suffer no internal damage but it may not provide accurate regulation. The regulator should be mounted in an upright position in a horizontal pipe run. Gas flow must be oriented to arrow on bottom casting. When selecting a regulator, Maxitrol recommends that the regulator is within one size of the manifold pipe size. Maxitrol also recommends 10 pipe diameters of straight pipe at the inlet & outlet of the regulator. Remote sensing is available. For "zero governor" applications, a counterspring is mounted beneath the valve. A maximum inlet pressure of 5 psi is recommended. Outlet pressure may be adjusted from -1.0'' W.C. to +1.5'' W.C. The Maxitrol 210 is designed to operate as a zero governor in the normal upright position. * CSA Approved
