High-Flow Industrial Gas Pressure Reducing Regulator for Natural Gas Distribution Systems

Marsh Bellofram T99 Marsh Bellofram Corporation, a division of the Marsh Bellofram Group of Companies and a leading supplier of industrial gas pressure regulation instrumentation for natural gas, propane, and utilities applications has its introduced its Type T99 industrial gas pressure reducing regulator.

Featuring a field-proven high-accuracy and highly robust design, Type T99 gas pressure regulators help to maintain consistent inlet pressures to downstream equipment, allowing for the accurate control of distribution system pressures, even with widely varying flow rates and supply pressures. This also include support of often challenging high inlet pressure and low flow control applications. Type T99 also eliminates the need for pressure-compensating meters by holding a steady pressure to the meter inlet. With these features, sudden downstream load changes are fully minimized.

Type T99 gas pressure regulators also feature tight shutoff, in which a heavy main spring is working through a lever to provide a high seat loading force. Regulator loading pressure bleeds downstream through the pilot via the downstream control line. No atmospheric bleed occurs when the regulator is shutoff. In addition, Type T99 regulators may be used as cost-effective drop-in replacements for most other industry models, including direct parts interchangeability, and occupy the same dimensional footprint. They are also easy to install, service and maintain. The valve disk and orifice may also be inspected without ever having to remove the body from the pipeline. Type 99 units can also be easily modified for special service requirements. Consult the factory for details.

With their exceptional high-reliability performance characteristics, Marsh Bellofram Type T99 gas pressure regulators are ideal for use within natural gas distribution systems; industrial boiler gas supplies, furnaces, ovens and mixers; plant air service; oxygen and ammonia service; and larger-scale commercial requirements, such as those common to shopping centers, schools, hospitals or nursing homes.
