About Product
The Onus PFB-002 is a direct acting, spring-loaded pressure regulator specifically engineered for very low outlet pressure applications. Compact and economical, this regulator is well-suited for use in industrial and commercial burner systems, combustion processes, and tank blanketing where space is limited but performance is critical.
Built to handle inlet pressures up to 10 bar(g), the PFB-002 is designed to maintain stable, low downstream pressure with high accuracy. Its rugged yet compact design makes it an ideal fit for installation in tight or space-constrained environments without compromising reliability.
Whether you're managing inert gas blankets in storage tanks or maintaining consistent flow in gas-burning equipment, the PFB-002 offers dependable control with minimal maintenance.
• GLANDLESS BODY DESIGN
With no gland to leak, this construction ensures zero gland leakage—a significant improvement over conventional bellows-seal valves. The absence of gland friction also results in greater sensitivity and consistent performance.
• 360° MOUNTING FLEXIBILITY
The PFB-002 can be installed in any orientation, making it ideal for tight or awkward installations.
• ENHANCED DIAPHRAGM PROTECTION
A reinforced diaphragm support system helps prevent internal damage by blocking full inlet pressure from reaching downstream components.
• IDEAL FOR INERT GAS BLANKETING
Perfectly suited for low-pressure inert gas blanketing in solvent and chemical storage tanks, maintaining safe pressure levels without over-pressurization.
• TAMPER-RESISTANT ADJUSTMENT
Equipped with a sealed adjustment screw and protective cap, the design minimizes the risk of unauthorized or accidental pressure changes.
• SERVICE WITHOUT LINE REMOVAL
The regulator’s internals can be accessed and maintained without removing it from the pipeline, reducing downtime and simplifying upkeep.
• LONG-TERM TIGHT SHUT-OFF
Built for longevity, the valve provides reliable shut-off performance throughout its service life, even in demanding operating cycles.
