BFA | LONG-STROKE ROLLING DIAPHRAGMS BFA

PRODUCT DESCRIPTION
Long-stroke rolling diaphragms are thin-walled, special sensitive diaphragms made from highly elastic materials with fabric reinforcement. Along with this standard design type BFA, the long-stroke rolling diaphragms can also be supplied made in special tools without fabric, type BFAO.
PRODUCT ADVANTAGES
The small diaphragm thickness and large height of the diaphragm relative to the diameter provide the following advantages:
- Low, almost constant resistance to movement over the entire stroke
- Considerably greater stroke lengths in comparison to conventional diaphragms with the same diameter
- Effective area remains the same over entire stroke
- No additional resistance to movement on starting or on change in direction of movement; no notch point in operating range
- Low requirements on piston and cylinder in comparison to lip seals.
