Materials of Construction
- Natural rubber or polyurethane (PU) sleeve
- Mild Steel bodywork, phenoline coated for protection
- EN57 Stainless Steel Shafts
Standard Sizes
- 100mm to 500mm
Options
- Options for fail action of actuator:
- Fail closed
- Fail open
- Fail fixed
- Double acting (fail open)
Features
- Reduced bore sleeve for better control
- The pinched slit of the double actuator pinch valve is orientated vertically so that the solids in suspension do not have to ride up over the rubber “weir” in the pinched sleeve
- Both actuators of the double actuator pinch valves are rigidly attached to the frame that is bolted to the pipeline providing a more stable valve
Applications
- Coarse abrasive slurries
- Slurry flow control
- Fast flotation machines
- Flash Roughers
