Types 1301F and 1301G H igh-Pressure R egulators The proven reliability and accurate regulation of the Types 1301F and 1301G (see figure 1) regulators make them ideal for numerous high pressure drop applications. They are direct operated, high-pressure regulators designed for inlet pressures up to 6000 psig (411 bar). The outlet pressures for the Type 1301 range from 10 to 225 psig (0.7 to 16 bar) in three separate ranges, while the Type 1301G range from 200 to 500 psig (14 to 35 bar) in one range. These multi-purpose regulators can be used as pilotsupply or pressure-loading regulators where high-pressure operating medium must be reduced for use by gas regulator pilots or pressure-loaded regulators. Their rugged design offers versatility for a wide variety of applications including air, gas, water and, other liquids. An optional spring case with a tapped vent and adjusting screw closing cap is available that enables the Type 1301F to be used as a pressure-loaded regulator.
