PRODUCT OVERVIEW
Pinch Valves
Flexible-sleeve isolation for suitable slurry, powder and solids-handling applications.
- Diameter range: 15–2000 mm
- Pressure rating: 1–10 MPa; burst pressure safety factor: 1:2
- Cast or welded valve bodies with a choice of sleeve materials
Product Description
Pinch valves control suitable slurry, powder and solids-bearing duties by compressing a flexible sleeve. The sleeve forms the flow passage and separates the medium from the operating mechanism. Sleeve material, actuation method and allowable differential pressure are selected together to suit the process.
