Long Life American Fisher Gas Pressure Regulator For Fire & Gas Systems 299H

 
Emerson American Fisher Model 299H Series Pressure Reducing Regulator
 

Fisher 299H Series pressure reducing regulators provide a broad capacity for controlled pressure ranges and capacities in a wide variety of distribution, industrial and commercial applications. Fisher 299H Series regulator has a pilot integrally mounted to the actuator casing. Fisher 299H Series regulators can handle inlet pressures up to 175 psi / 12.1 bar depending on orifice size.

Available Constructions
Type 299H: Pilot-operated pressure reducing regulator with a pilot integrally mounted to the actuator casing.

Unique No Bleed Monitor System
High-Capacity Pressure Control
Easy to Maintain
Rugged Construction

Features

• Compact in Size—Small envelope because of the built-in pilot and internal registration.
• Unique No Bleed Monitor System—Flexible worker/monitor system setup that allows for bleed to be piped to the intermediate piping thus eliminating downstream bleed which reduces lost and unaccounted for gas. Another advantage of this configuration is that the system lockup pressure is that of the worker instead of the monitor.
• Not an Adaptation of Existing Regulators—New design of integrated cases and internal registration ports.
• Wide Variety of Applications—Natural gas distribution systems, gas supply to industrial boilers, furnaces, ovens, mixers, plant air service.
• Accuracy—Keeps constant inlet pressures to downstream equipment by accurately controlling distribution system pressures at widely varying flow rates and supply pressures for maximum efficiency and best operation, or by eliminating the need for pressure-compensating meters by holding a steady pressure to the meter inlet.
• High-Capacity Pressure Control—Actuator diaphragm responds quickly to downstream pressure change, causing immediate correction in main valve position. Pilot responds simultaneously and controls final positioning of main valve. This action permits full main valve travel, resulting in higher capacity than could be obtained without an external pilot regulator.
• Rugged Construction—With a two bolt connection of the regulator to the body and no union ring, the 299H Series regulators are designed for longer service life with minimal maintenance requirements.
