1301 Series High-Pressure Regulators Figure 1. Type 1301F Regulator • Durable Stainless Steel Diaphragm—For high-outlet pressure applications. • Spare Valve Disk Provided—Extra valve disk through a reversible disk holder assembly. • Versatility—Can control a variety of media including air, gas, water, and other liquids. •ANSI Class VI Shutoff—Soft-seat valve plug disks ensure tight shutoff. • Sour Gas Service Capability—Optional materials are available for applications handling sour gases. These constructions comply with the recommendations of NACE International Standards MR0175 and MR0103. The proven reliability and accurate regulation of the 1301 Series regulators (see Figure 1) make them ideal for numerous high-pressure drop applications. They are direct-operated, high-pressure regulators designed for inlet pressures up to 6000 psig /414 bar. The Type 1301F can handle outlet pressures from 10 to 225 psig / 0.69 to 15.5 bar in three ranges and the Type 1301G can handle outlet pressures from 200 to 500 psig /13.8 to 34.5 bar in These multi-purpose regulators can be used as pilot supply or pressure-loaded 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. Process Management

Type 1301G Cv Coefficients'1'— Incompressible Fluid Maximum Allowable Pressure Drop for Liquid Pressure drops in excess of allowable will result in choked flow and possible cavitation damage. Choked flow is the formation of vapor bubbles in the liquid flowstream causing a condition at the vena contracta which tends to limit flow through the regulator. The vena contracta is the minimum cross-sectional area of the flow stream occurring just downstream of the actual physical...
