F627 High Flow Gas Regulator

Product catalog summary

Overview: The F627 pilot-operated pressure reducing regulator is engineered for optimal performance in fixed-factor billing applications. It includes a factory-installed PL81 pilot and necessitates a downstream control line for external registration.

Key Features:

Accuracy: Ensures pressure is maintained within ±1% of the absolute outlet pressure setting, minimizing pressure variations across extensive flow and inlet pressure ranges.
Flow Capabilities: Provides a variety of body and orifice sizes to suit different applications.
Tight Shutoff: Features a flat disk made of nitrile or fluorocarbon for superior shutoff capability.

Specifications:

Outlet Pressure Ranges: 5 to 35 PSIG (0.34 to 2.41 BAR) and 35 to 100 PSIG (2.41 to 6.90 BAR).
Maximum Pressures: Outlet pressure up to 250 PSIG (17.24 BAR), with inlet pressure up to 250 PSIG (17.2 BAR), except for 1/2" orifice which is 125 PSIG (8.62 BAR).
Body Sizes: Available in 3/4 NPT (DN 20), 1 NPT (DN 25), and 2 NPT (DN 50).
Temperature Range: Operates between –20˚ to 180˚F (–29˚ to 82˚C).
Weight: Varies based on casing material, ranging from 9.3 lbs (4.2 kg) to 18 lbs (8.16 kg).

Materials of Construction:

Main Regulator: Constructed from ductile iron, steel, or LCC steel body with die-cast aluminum or steel spring and diaphragm cases.
Pilot Regulator: Composed of an aluminum body and spring case with a nylon fabric diaphragm coated with nitrile or fluorocarbon.

Rebuild Kits: Available for both nitrile and fluorocarbon trims, including diaphragms, valve disks, O-rings, and retaining pins.

Flow Capacities: Detailed flow capacities are provided for various orifice sizes and body configurations, ensuring optimal performance across different pressure settings.

Dimensions: Specific dimensions are provided for both aluminum/cast ductile iron units and flange units, detailing measurements for various body sizes and configurations.

Parts List: A comprehensive list of parts with corresponding part numbers is provided, covering components such as closing caps, springs, diaphragms, and orifices.

Catalog excerpts

F627 High Flow Gas Regulator The F627 pilot operated pressure reducing regulator provides superior performance when used in fixed-factor billing applications. The Type F627 includes a factory-installed PL81 pilot and has external registration that requires a downstream control line. Features • Accurate for Pressure-Factor Measurement Applications — Pilot action controls pressure to within ±1 percent of the absolute outlet pressure (PSIA) setting at full travel. This capability results in low-pressure variations over broad flow ranges and inlet pressure ranges. • Wide Range of Flow Capabilities — A variety of body and orifice sizes are available. • Tight Shutoff Capability — A flat disk of nitrile or fluorocarbon provides excellent shutoff capability. Flanged Body with Ductile Iron Casings
