REact 60DC Pop and REact 100DC Pop

We are very pleased to announce the launch of two new products which are available for delivery from 01 September 2020.

First of all after the success of the REact30 PoP, we are expanding the range with the REact60DC PoP and the REact 100DC PoP with the same features:

  • Fail- Safe and ECU function with max. force and stroke of the actuator
  • for all plugs available
  • 24DC and 90 to 264VAC
  • flow to open and flow to close
  • NRTL (UL and CSA) certificated
  • Different Fail-Safe speeds
  • And many more


New REact L. with emergency closing device

Then our new REact L, launched beginning of this year with closing forces of 15kN, 22kN and 30kN, is now available with an emergency closing device option (Fail-Safe) for the 15kN and 22kN versions.

The Fail-Safe function with a stroke up to 4 inch will close the valve smoothly even at large pressure differences because of an adjustable closing time. It should also be mentioned that after a Fail-Safe operation, an automatic return to normal operation is possible.
