AVK swing check valve variant prepared for limit switch

The new variant is prepared for mounting a limit switch for indication of closed position. 13-04-2022

The limit switch is activated by an eccentric cam disc mounted with a set screw on the shaft for lever and weight. The set screw enables adjustment of the cam disc position that gives the signal. Since the disc will move slightly up and down in the flow in open position, it does not make sense to get a signal indicating open position. 

Please see datasheet and mounting instruction for further details: Series 41/60-001 

Kits containing limit switch and mounting bracket are available as accessories. 

The swing check valves can be installed with lever and weight or with bare shaft.  

Product insights

Swing check valves

A swing check valve is mounted with a disc that swings on a hinge or shaft. The disc swings off the seat to allow forward flow and when the flow is stopped, the disc swings back onto the seat to block reverse flow. 

AVK offers swing check valves in DN 50-600 with lever and weight, lever and spring or with closed bushings. AVK swing check valves feature very easy access to maintenance and can be installed in both horisontal and vertical positions.
