Flow control / limiting valve with non-return function

The flow control / limiting valve limits a preset max. flow from a higher pressure zone to a lower pressure zone, independent of varying operating pressures. The nominal flow is infinitely adjustable via the pilot valve up to +/- 15%. The non-return function prevents return flow when the inlet pressure is lower than the outlet pressure.

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)

Components:
1: main valve
2: ball valve (A, B, C)
3: filter
4: orifice
5: throttle check valve
6: pilot valve
7: differential pressure measuring orifice plate
8: optical position indicator with vent plug (option: electric position indicator, opening limiter)
9: check valve (A, B)
10: needle valve
11: manometer with ball valve (A, B)
B: DN 40- DN 150: 22 mm
DN 200 - DN 250: 27 mm
DN 300: 29 mm
X: 5 x DN pipe
Y: 3 x DN pipe
