ATMOSPHERIC PRESSURE 54A2767 a A2505 INLET PRESSURE TUBING CONNECTION Figure 3 Schematic of Type 99 Regulator with Type 61HP Extra High Pressure Pilot through the relief valve body J Figure 4 Since loading pressure needs to exceed outlet pressure only moderately to stroke the main valve fully open a continued increase in loading pressure differential extends the main diaphragm E and the pusher post assembly K far enough to separate the bleed valve D and the bleed orifice H This permits quick dumping of excess loading pressure into the downstream system With a decrease in loading pressure on top of the main diaphragm E the main spring B exerts an upward force on the diaphragm rod connected to the main diaphragm E pulling it upward This moves the main valve toward its seat decreasing flow to the downstream system Diaphragm G in the pilot valve acts as a sealing member for the loading chamber and as a balancing member to diaphragm F These two diaphragms are connected by a yoke so any pressure change in the pilot chamber has little effect on the position of the pilot valve Therefore the active diaphragm in the pilot is F and the pressure on the top side of this diaphragm opposes the force of the pilot control spring A Monitoring Systems Monitoring regulators serve as overpressure protection devices to limit system pressure in the event of open failure of a working regulator

Instruction Manual Form 589 April 2008 Type 99 Type 99 Pressure Reducing Regulators Introduction Scope of the Manual This manual describes and provides instructions and parts lists for Type 99 pressure reducing regulators complete with standard P590 Series integral filter However complete instructions and parts listing for the Type 1301F pilot supply regulator and other Fisher equipment such as monitoring pilots will be found in separate instruction manuals Description The Type 99 gas regulators provide a broad capacity for controlled pressure ranges and capacities in a wide variety of distribution industrial and commercial applications A Type 99 regulator has a Type 61L low pressure Type 61H high pressure or a Type 61HP extra high pressure pilot integrally mounted to the actuator casing as shown in Figure 1 The Type 99 regulator can handle up to 1000 psig 69 0 bar inlet pressures the 1000 psig 69 0 bar regulator requires a Type 1301F pilot supply regulator and a Type H110 pop relief valve The pilot supply regulator reduces inlet pressure to a usable 200 psig 13 8 bar for the extra high pressure pilot This regulator comes standard with O ring seals on the guide bushing and valve carrier key 26 Figure 7 to keep main valve body outlet pressure from interfering with outlet pressure in the lower casing assembly key 29 Figure 9 Specifications Since a pilot operated regulator is construct
