BFA Diaphragms: Precision in Motion

Experience unparalleled precision and efficiency with BFA Diaphragms' revolutionary long-stroke rolling diaphragms. Crafted from highly elastic fabric-reinforced materials, these diaphragms are designed to excel in applications requiring delicate yet robust protection. The unique BFA Diaphragms lineup includes the standard type BFA and the fabric-free type BFAO, catering to specialized needs.

Unveiling Advantages: Long-Stroke Excellence

BFA Diaphragms redefine diaphragm technology with their slender build and remarkable height-to-diameter ratio. The benefits are manifold: experience low, consistent resistance across the stroke, enabling significantly extended lengths compared to traditional counterparts. Enjoy uniform effective areas throughout the motion, eliminating resistance during initiation or changes in movement. Ideal for hydraulic and pneumatic control systems, pressure measurement, and display equipment, these diaphragms outperform lip seals while minimizing demands on pistons and cylinders.

Applications Across Industries: Precision Perfected

BFA Diaphragms find their niche in applications demanding precision, reliability, and extended stroke capabilities. From hydraulic and pneumatic control equipment to pressure switches and transducers, their superior performance is unmatched. The specialized 'no-dust' design makes them particularly effective in low-pressure environments, safeguarding machinery from contaminants. The integration of BFA Diaphragms ensures optimal performance, while their construction eliminates concerns about dust infiltration.

Effortless Installation: Precision in Practice

Unlock the full potential of BFA Diaphragms with meticulous installation. When assembling long-stroke fabric-coated roller diaphragms, place the fabric on the depressurized side. Reverse the diaphragm before fitting, ensuring the rolling convolution is correctly oriented. For optimal results, employing a mounting sleeve is recommended to prevent unintended damages. Alternatively, position an inverted rolling diaphragm on the piston, insert the heel into the groove, and push the piston into the cylinder to form the rolling winding without skewed convolutions. Incorporate a stroke limitation to ensure peak performance.

In conclusion, BFA Diaphragms introduce a new era of precision and reliability in long-stroke rolling diaphragms. With their innovative design, extended stroke lengths, and uniform resistance, they redefine efficiency in hydraulic and pneumatic systems. Meticulous assembly guarantees optimal performance, establishing them as the ultimate choice for industries that demand precision, longevity, and unmatched performance.
