Pipe-break safety valve, hydraulic control
| Material: |
Body parts, orifice plate, housing: stainless steel, Hawle epoxy powder coated Control line, orifice plate: stainless steel Diaphragms, gaskets: EPDM Solenoid valve: stainless steel |
|---|---|
| Max. operating Pressure: | See table |
| Medium | Water |
The hydraulically controlled pipe-break safety valve monitors the volume flow rate via the differential pressure measuring orifice (8). In case of a pipe burst the volume flow rate is increased, the pressure difference at the differential pressure measuring orifice (8) gets higher. The pipe-break safety pilot valve (5) is changed over and the base valve is closed. Via the throttle check valve (4) the valve closing rate can be adjusted.
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 upstream of the orifice plate(x = 5 x DN) and between the orifice plate and the main valve (y = 3 x DN!
For rating, please specify the following:
- Max. admissible flow rate
- Inlet pressure (P1 side)
- Outlet pressure (P2 side)
Components:
1: main valve
2: ball valve (A, B, C)
3: filter

5: pilot valve
6: manometer with ball valve
7: optical position indicator with vent plug (option: electric position indicator, opening limiter)
8: differential pressure measuring orifice plate
B: DN 40-150: 40 mm
DN 200-300: 44 mm
X: 5 x DN pipe
Y: 3 x DN pipe
