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.

1. The pressure/temperature limits in this bulletin and any applicable standard or code limitation for valve should not be exceeded.
Principle of Operation The Type 1301 regulators are direct operated. Downstream pressure is registered internally through the body to the underside of the diaphragm. When downstream pressure is at or above set pressure, the disk is held against the seat and there is no flow through the regulator. When demand increases, downstream pressure decreases slightly allowing the regulator spring to extend, moving the yoke and disk assembly down and away from the seat. This allows flow through the body to the downstream system.
To determine regulating capacities at pressure settings not given in tables 3 and 4, or to determine wide-open capacities for relief sizing at any inlet pressure, use the Catalog 10 liquid sizing procedures in conjunction with the appropriate liquid sizing coefficients (Cv and Km see Specifications section). Convert cubic meters per hour according to the preceding paragraph if necessary. Liquid Sizing for Liquids Other than Water Q CV
P G
Capacity Data Air Capacities Regulating capacities at selected pressures and outlet pressure flows are given in scfh (60°F and 14.7 psia) of air at 60°F. To determine the equivalent capacities for other gases, multiply the table capacities by the following appropriate conversion factors: 1.29 for 0.6 specific gravity natural gas, 0.810 for propane, 0.707 for butane or 1.018 for nitrogen. For gases of other specific gravities, divide by the square root of the appropriate specific gravity. If capacity is desired in normal cubic meters per hour at 0°C and 1.01325 bar, multiply scfh by 0.0168. See tables 1 and 2 for air capacities.
Where: Q = Flow in gpm ∆P = Valve differential in psi Cv = Valve sizing coefficient (see Specification section G = Specific Gravity
Example: 5/64-inch orifice Glycol (Specific Gravity) = 1.11 Pinlet = 500 psig (34.3 bar) Pout (set point) = 225 psig (15.4 bar) CV = 0.097 from table 5 Calculate capacity based on 20% offset from set point Pout at full flow = 225 psi (15.4 bar) set point – 45 psi (3.08 bar) offset = 180 psi (12.3 bar) ∆P = 500 – 180 (34.3 –12.3 bar) = 320 psi (21.9 bar)
Water Capacities Tables 3 and 4 give capacities in U.S. gallons per minute of water (multiply by 0.2271 to convert to cubic meters per hour of water).

Bulletin 71.1:1301 Maximum Allowable Pressure Drop for Liquid Service 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 crowding 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 restriction. Cavitation and flashing are physical changes in the process fluid. The change is from the liquid state to the vapor state and results from the increase in fluid velocity at or just downstream of the greatest flow restriction, normally the regulator orifice. To determine the maximum allowable pressure drop for water: ∆P(allow) = Km (P1) Where: ∆P = Valve differential — psi

Installation Types 1301F and 1301G may be installed in any position. Spring case vents must be protected against the entrance of rain, snow, debris, or any other foreign material that may plug the vent openings. The inlet connection is marked ‘‘In’’ and the two outlet connections are marked ‘‘Out.’’ If a pressure gauge is not installed in one outlet connection, plug the unused connection. See figure 2 for dimensional drawing.
