For Pumps
- Enables more compact construction of the pump canopy.
- Low service time – our ball check valves take less than 15 minutes to service.
- Quick replacement time – customers can quickly replace the valve balls themselves without damaging the equipment.
For Lift Stations
- Space saving – our valves enable space saving in a liftstation therefore giving the possibility of using a much smaller tank.
- Quick replacement time – customers can quickly replace valve balls themselves without damaging the equipment.
- Full opening at the velocity of 2.3 fps – the SZUSTER system check valves are fully opened at the velocity of 2.3 fps, thereby enabling the efficient work of the customer’s system.
- Significant reduction of vibration – our check valves successfully reduce vibrations thereby making the system work more quietly.
For Waterworks
- Full opening at the velocity of 2.3 fps – fully open position and constant factor K, starting from the flow rate of 2.3 fps.
- Easy access to valves interior and the ball which enables:
– placing the cover in the so-called servicing position
– inspection of the inlet pipeline (including the pump rotor) and inspection of the pressure pipeline - Reduction of vibrations making a system work more quietly.
For Engineers
- Combined solution – a two-in-one compact solution (elbow, check valve) or even a three-in-one compact solution (elbow, check valve, knife gate valve).
- Fully open position and constant factor K starting from the flow rate of 2.3 fps.
- Reduction of vibrations making a system work more quietly.
Elbow Ball Check Valves
Will That Clog the Valve?
