Bulletin 71.1:133 January 2007 133 Series Self-Operated Regulators Features   •  Wide Pressure Range Capability with Single     Regulator—Type 133H may also use Type 133L    springs, allowing pressure settings to be varied    between 2-inches w.c. and 10 psig (5 mbar and    0,69 bar) by changing springs.   •  Types 133L, 133H and 133HP Suitable for     Monitoring Applications—O-ring stem seal on    Types 133L, 133H and 133HP isolates body    pressure from controlled pressure.   •  Excellent Shock Characteristics and Fast     Speed of Response—Due to two-way stabilizer    vent valve, which vents the spring case more    rapidly than conventional vents, lag in diaphragm    and valve disk movement is minimized. W1327/IL types 133H, 133l and 133z regulators   •  Bubble-Tight Shutoff—Single-port construction,    large diaphragm area, and light-rate springs along    with disk material and seat design provide low    lock-up pressures.   •  Spring and Diaphragm Effects Minimized     boosting system provides excellent performance     over a wide range of flow conditions.   •  No Seat-to-Seat Adjustment Required—Balanced    single-port design eliminates necessity for seat-to    seat adjustments to achieve bubble tight shutoff.   •  Easy Access to Trim Parts—Valve seat, disk, and    cage easily removed with body remaining in line     and without disassembly of actuator portion; orifice    is not threaded in.   •  Reusable Pressure Seals—O-rings used for    pressure seals, unlike gaskets, are not ordinarily    damaged by disassembling the regulator.   •  Resistance to Piping Stresses—Steel    constructions are available to help resist pipe stresses.

Bulletin 71.1:133 Introduction Description The 133 Series self-operated gas regulators, shown on the cover are primarily designed for industrial and commercial applications supplying gas to furnaces, burners and other appliances. The 133 Series balancing system enables the regulator to provide accurate control of gas pressure for maximum combustion efficiency despite varying inlet pressure conditions. The single port construction provides bubble tight shutoff. An external downstream control line is required for the operation of the regulator. Refer to Table 1 for outlet pressure ranges of each...

Bulletin 71.1:133 Balancing Diaphragm B0098-3/IL Inlet pressure Registration disk Boost pressure Downstream pressure Type 133L regulator Figure 4. Operational Schematics This pressure registered on the top of the balancing diaphragm aids downward disk travel and compensates for spring and diaphragm effect. This improves regulator rangeability and performance. Two-Way Stabilizer Vent Valve on Types 133H, 133L and 133Z When the regulator responds to an increase in downstream pressure, the diaphragm moves upward. As the diaphragm rises, movement of air forces the lower vent flapper upward, carrying...

Table 1. 133 Series Outlet Pressure Ranges, Control Springs Table 2. Maximum Inlet and Outlet Pressures Capacity Data Flow capacities for various inlet pressures and outlet pressure settings are shown in Tables 3 to 10. Capacities for Tables 3 to 10 are in thousands of cubic feet per hour of 0.6 specific gravity gas at 60°F and 14.7 psia. To convert to equivalent capacities of other gases, multiply the values shown by the appropriate For optimum performance, select the lowest spring range that includes the desired outlet pressure setting. For restricted-capacity constructions, determine flow...

TWO-WAY STABILIZER VENT VALVE IN "UP" POSITION Figure 5. Types 133H, 133L and 133Z Stabilizer Vent To determine capacity using the flow coefficient Cg, use the appropriate procedure below. 1. If flow is critical (absolute outlet pressure is equal to or less than one-half the absolute inlet Capacity = (Absolute Inlet Pressure) (Cg) (1.29) The capacity determined will be in standard cubic feet per hour of 0.6 specific gravity gas. 2. If flow is less than critical (absolute outlet pressure is greater than one-half the absolute inlet pressure), use the Fisher sizing slide rule or the sizing nomographs...
