Burkert 5281A12FKMBR Servo Assisted Diaphragm Valve

The Burkert 5281A12FKMBR is a 2/2-way servo-assisted diaphragm valve that uses a servo-diaphragm and push-over solenoid to deliver precise, damped actuation for shutting off or metering liquids and gases. Built with a brass body (BR) and FKM seals, it accommodates diaphragm orifice sizes from DN 13 to DN 65 mm, with stainless-steel inner parts and supports both threaded and flange connections for flexible installation. The valve operates in NC or NO configurations, features waterhammer-free and low-noise performance with a tight closing action, and offers a compact installation length suitable for space-constrained panels. The 120 V coil variant aligns with standard control circuits, and the unit is intended for neutral media such as compressed air and water, using NBR, EPDM, or FKM seals to match service conditions and temperature ranges.
