EUROSTOP flanged ductile iron butterfly valve isolating device
Reserved for water and suitable for high pressure, the long pattern EUROSTOP ISO 5752 series 14 flanged ductile iron butterfly valve has double eccentricity and a watertight joint located in the disc of the butterfly.
The EUROSTOP flanged butterfly valve with push-in butterfly joint comes in three versions – manual version, motorized version, and a version for underground service.
- Durability: when open, the butterfly valve gains durability because the compression point is absent.
- Ease of use: The butterfly valve is extremely simple to use thanks to its push-in butterfly joint, which does not require any adjustment.
- Flexibility: this watertight push-in joint acts like an autoclave; the higher the service pressure is, the more watertight the valve becomes, irrespective of the direction of the flow of fluid over time. It holds longer than the joint by minimizing the constraints it is subjected to. Its flexibility allows a reduction of the closing torque by deformation and when it comes alongside the seat it ensures constant torque.
- High performance: the double eccentricity means that the joint can free itself completely from the seat at the start of the opening movement, thereby minimizing friction between the rubber and seat.
