Anleitung Zusammenfassung
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 !Warning Since a pilot-operated regulator is constructed of both a pilot and a main valve, care should be used not to exceed the maximum inlet pressure shown on the nameplate of either unit. When inlet pressure exceeds the pilot limitation, a pilot supply reducing regulator and/or relief valve will be required. Specifications and ratings for various Type 99 constructions are listed in the Specifications section on page 2. Some specifications for a given regulator as it originally comes from the factory are stamped on nameplates located on the pilot and actuator spring cases. A tag (key 159, Parts List) additionally may be installed on the pilot to indicate a regulator with O-ring stem seal. These regulators and their installations should be checked for compliance with applicable codes. W2676 Figure 1.

The pressure/temperature limits in this Instruction manual and any applicable standard or code limitation should not be exceeded. 2. For stability or overpressure protection, a pilot supply regulator may be installed in the pilot supply tubing between the main valve and pilot. 3. Type 61LD construction has narrower proportional band than does the standard Type 61L pilot. 4. Type 61LE construction has broader proportional band than does the standard Type 61L pilot. Table 1.
