Installation
Fig. 4 Installation example, GNVP
The GNVP non-return valve is fitted between two DIN
flanges, such as pump flange and counter flange, by
means of bolts and nuts. The valve can be fitted in any
position required. The arrow on the nameplate
indicates the direction of the water flow.
Note: The GNVP valves have factory-fitted O-rings on
both mating surfaces for optimum sealing against the
flanges. As a result, no additional gaskets are
required.
