Nominal Pressure Level
PS 25, PS 40, PS 63
RVA Stop Check Valves
The check valves open and close independently by means of the pressure exerted by the working medium upon the valve disc. The RVA check valves have an additional lifting stem with which the valve can be permanently closed.

PS 25, PS 40, PS 63
RV Check Valves
The check valves open and close independently by means of the pressure exerted by the working medium upon the valve disc. The valve closes independently when a flow interruption or back flow are detected.
Nominal Pressure Level
PS 25, PS 40, PS 63
RVAK Stop Check Valves
The check valves open and close independently by means of the pressure exerted by the working medium. RVAK stop check valves employ a lifting stem to permanently close the valve and additionally a cone on the underside of the valve disc for medium flow regulation.
Nominal Pressure Level
PS 25, PS 40, PS 63
RVZ Check Valves
RVZ check valves housings are installed between flanges and are also available with a linear ball bearing for a smoother function.
