The safe choice for Food Retail and Industrial Refrigeration applications

With the SFA 10 and DSV 10 change-over valve, Danfoss is widening its range of highly reliable safety valves designed to industrial standards. The new safety valves with their lower capacity and higher pressure range up to 65 bar provide more flexibility in system design. The SFA 10 can now be used in C02 applications on the low-pressure site as well as in low-charge ammonia systems. Furthermore, the spring housing is designed for reliability, increased lifetime, and to have no sudden reliefs below set pressure.

SFA 10 has a cone/seat design that guarantees a stable and reliable set of pressure. The SFA 10 is designed with narrow tolerances and with an O-ring sealing which is more robust and less sensitive to dirt which ensures perfect reseating once it has been activated. The sealing wiring is shorter to avoid the risk of getting it damaged during handling or installation; and the maintenance and servicing options have been improved to make it easier and safer.

Features and benefits

  • Easy installation

  • Perfect reseating

  • Unchanged setpoint

  • Trouble-free service
