Die-cast body with lightweight aluminum alloy, the disc is lined with wear-resistant steel core polymer material, soft and wear-resistant rubber ring seal makes it very suitable for the formation of various interest powder, granular materials application, especially for the strong abrasive materials.
Series - 150 | PN10-PN25
Cement butterfly valve is the company developed specifically for powder, granular materials for industrial products. In need of gravity blanking or pneumatic conveying powder, granular material handling systems, butterfly valve are often installed in the hopper, silo, screw conveyor outlet and a gas delivery pipeline.
Design Features
- Stem sealing is not easy deformation, so avoids leakage phenomenon
- Overall support is good, stable and solid
- Use less rubber of seat, so expansion has small impaction and easy to control torque value at an appropriate range
- Applying to two pieces of no-sells connection ,structure is simple and convenient to be maintained
- Butterfly disc owns automatic alignment function and achieved small combination of disc and seat
- For seat sealing surface and phenolic back as a whole ,it can reduce amount of deformation
