Art.Nº: 1303

Application: for use in drinking water sector (other on request)

DN: 1 1/2" - 2" PN16

DN200 - DN300 PN10 

DN40 - DN300 PN16

CHARACTERISTICS

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 electric solenoid valve controls the filling and emptying of the pilot chamber. The main valve is closed at zero current and opened when energized. To avoid water hammers, the closing rate can be adjusted via the throttle check valve.

Version/position of main valve:
- Closed at zero current (model no. 1303)
- Open at zero current (model no. 1304)

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)

- Voltage (e.g. 24 V / 230 V)
- Type of power (alternating current / direct current)
- Type 1303 or 1304
