Installation manual Envalve series VK, VKF and PVK
Page 13 of 23
When the valve is positioned correctly between the collars the flanges can be shoved over the collars and
secured with the metal bolts and nuts (NW75 and larger) or the nut can be tightened (NW63 and smaller).
After installation the connection must be checked; try to operate the valves manually by closing and
opening them by hand. This must be able without scraping noise and with only moderate force. See
paragraph 1.3 for instructions on manual operating.
Do not tighten the bolts and nuts too much, this will deform the seal and possibly block the paddle!
