FlowCon EVS 1D95011 - 06/2023 Installation and Operation Instruction The FlowCon EVS is a plug-in insert used with three different FlowCon valve housings: FlowCon A DN15-25 (1/2”-1”) FlowCon AB DN15-25 (1/2”-1”) FlowCon ABV DN15-25 (1/2”-1”) the SS-insert in proper position during operation. Now install the EVS in the valve housing. In case of design change, the SS-insert can be removed from the EVS by unscrewing the lock ring and pulling the SS-insert out. The SS-insert’s O-ring will also come out. Place a new O-ring and fit the new SS-insert as described above.

A Figure 1 Insert Setting and Installation Prior to installing the FlowCon EVS in the valve housing, the system should be properly flushed. Blank valve covers are available to be installed during flushing. It is recommended to grease the O-rings located around the EVS with silicone grease before in- stalling the EVS in the valve housing. It is not necessary to grease – but will not harm if done – the stainless steel insert’s O-ring. When fitting the factory pre-set stainless steel insert (SS-insert) into the EVS, first place the SS- insert’s O-ring on the inside groove of the EVS BEFORE fitting the SS-insert. Hereafter push the SS-insert into the EVS with a hard push. Once in fully, the SS-insert is correctly fitted and the lock ring is screwed on tight. The lock ring will hold B C D E Figure 2 Once the EVS incl. SS-insert is properly fitted in the valve housing, the required actuator may be applied. Please see specific installation instruc- tion for selected actuator.
