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.
• Highest Quality— Designed and manufactured
to ISO 9001 standards.
• 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.
• Optional Token Relief—The Types 299HR and 299HSR with an integral token relief in the pilot is designed to relieve minor overpressure caused by thermal expansion.
• High-Capacity Pressure Control—Actuator diaphragm responds quickly to downstream 1pressure 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.
• Easy Registration Conversion—Two screws and O-rings change internal registration to external or dual registration.
• Easy Startup—No special procedure required.
