Emerson Tartarini Pneumatic Gas Regulator 2 FL BP/FR Back Pressure Low Pressure Carbon Steel Reducing Regulator

Tartarini FL-BP Series Back Pressure Regulator

Product Overview

The Tartarini FL-BP is a pilot-operated back pressure regulator (or relief valve) in the FL family. It maintains constant upstream pressure by opening when pressure exceeds the setpoint and relieves excess gas. It is commonly used in gas distribution stations and industrial systems to protect upstream equipment or control line pressure.

Features

• Pilot-operated for accurate upstream pressure control
• Balanced valve plug design – stable regulation
• High flow capacity with low droop
• Soft-seat tight shut-off
• Easy pilot adjustment and maintenance
• Internal relief or slam-shut options available
• Robust ductile iron or steel body

Applications

• Gas pressure relief stations
• Upstream pressure control in distribution networks
• Burner train protection
• Overpressure relief in industrial gas lines
• Compressor discharge regulation

FAQ

Q: What does back pressure mean here?

A: It controls and maintains upstream (inlet) pressure by relieving excess gas.

Q: Can it be used as a relief valve?

A: Yes – acts as a back pressure regulator/relief device.
