4. CONTROL SPRING DOWNSTREAM CONTROL LINE DIAPHRAGM REGISTRATION DISK Figure 2 Operational Schematic of Type 133L Regulator Also Typical of Type 133H downstream system Decreased demand increases the downstream pressure and moves the diaphragm and stem assembly up closing the valve disk and decreasing the gas supply to the downstream system Boosting System The 133 Series incorporates a balancing diaphragm and a boosting system When the regulator is locked up inlet pressure is registered on the top of the valve disk and on the bottom of the balancing diaphragm through registration holes in the top of the cage Also downstream pressure is registered on the bottom of the valve disk and on the top of the balancing diaphragm through a passage formed by grooves in the registration disk and an annular space between the stem and stem sleeve When the valve disk is open gas flows from the inlet over the edge of the valve disk to the outlet Under the valve disk near the registration disk there is little gas flow The gas pressure near the registration disk is higher than it is in the flow path where gas velocity tends to lower the pressure The higher pressure near the disk is registered on the top of the balancing diaphragm through the registration disk and the annular space between the stem and stem sleeve This pressure registered on the top of the balancing diaphragm aids downward disk travel and compensates fo
5. Ranges of available springs are shown in Table 1 When changing the spring also change the nameplate located on the casing flange to indicate the outlet pressure range Shutdown Isolate the regulator from the pressure system and release pressure from the outlet and the control line Inlet pressure will then automatically be released as the regulator opens up in response to the lowered pressure on the diaphragm Maintenance This section includes instructions for disassembly and replacement of parts All key numbers refer to Figures 10 11 12 and 14 except where indicated To avoid personal injury property damage or equipment damage caused by sudden release of pressure or explosion of accumulated gas do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure from the equipment Do not loosen the diaphragm casing cap screws keys 35 and 36 when the control spring key 12 has spring force applied to it Release the spring compression as described in step 7 Due to normal wear that may occur in gas regulators parts must be periodically inspected and replaced if necessary The frequency of inspection maintenance and replacement of parts depend upon the severity of service conditions or requirements of local state and federal regulations Types 133H 133L and 133Z Disassembly 1 Disconnect the downstream control line from the
