Flow control / limiting valve with float control

The flow limit / control valve limits a predetermined max. flow into a tank, independent of varying operating pressures and considering the water level in the tank. The nominal flow is infinitely adjustable via the pilot valve up to +/- 15%. If the maximum water level in the tank is reached, the main valve is closed. To avoid water hammers, the closing rate can be adjusted via the throttle check valve. The difference between minimum and maximum water level can be adjusted between 60 and 900 mm via the stops at the float rod.

Minimum inlet pressure: 1 bar (Please consider: pressure loss due to main valve and orifice approx. 0.5 bar)

Make sure to allow for flow calming sections between the main valve and the orifice plate (x = 5 x DN) and downstream of the orifice plate (y = 3 x DN)!

For rating, please specify the following:
- Flow rate to be limited
- Inlet pressure (P1 side)
- Outlet pressure (P2 side)
- Difference between min. and max. tank level

1: main valve
2: ball valve (A, B, C)
