Exchangeable Soft Seated Low Friction Regulating Butterfly Valve
Description
Center Lined Soft Seated Butterfly Valve are reliable, maintenance-free shutoff and control valves with permanently gas-tight seals. This resilient seated valve has proved itself as a leak-free and corrosion resistant valve in various applications under demanding operating conditions.
Features & Benefits
| SOFT SEATED BUTTERFLY VALVE | ||
| 1 | EN ISO 5211 top mounting | Easy coupling with every king of drives. |
| 2 | Three guiding bushings on the shaft | It grants a perfect alignment of the shaft on the body and prevents oscillation even with high pressure |
| Less friction between the shaft and body. | ||
| 3 | Vulcanized liner on rigid ring | Less deformation of the liner |
| Easy assembly/disassembly of the liner of maintenance | ||
| No deformation of the liner between the flanges during assembly. | ||
| Greater dimensional accuracy during the injection/molding. | ||
| 4 | Shaft in 2 pieces without fixing components | Easy assembly/ disassembly of the disc for maintenance |
| Higher Kv thanks to the central section of the disk thinner than a valve with a single shaft | ||
| 5 | Lapped surface of the disc’s circumference | Better tightness and less wear of the liner |
| Lower torque due to less friction between the disc and liner. | ||
Features:
- Face to face as per EN 558 series 20
- Integral sealing which avoids any contact between fluid and valve body
- Sealing design allowing perfect adherence to the valve body and perfect tightness to the flanges, without additional parts, clamping between flanges does not influence the torque of the valve.
- Lapped disc edges that allows better tightness, reduced torque and low wear of the liner
- Bushes to support the shaft.
- Valve neck with top work as per EN ISO 5211 for easy connections with all different types of actuators.
- All components properly treated against corrosion
