Ghibson - Butterfly Valve HD

The Advantages of the HD-series Explained

Accurate coupling

The HD-series from Ghibson is designed with a shaft-disc connection that is specifically shaped, so ensures an accurate coupling and avoid clearances.

Higher shaft tensile capacity

The specifically shaped shaft-disc connection also is a larger section than the classic squared one. Therefore, the design allows for higher shaft tensile capacity.

Ensured sealing even at high temperatures

As the HD-series consists of two sets of Belleville washers it ensures the sealing along the valve shafts even at high temperatures.

Avoid possible damage on sealing

These thrust of the two sets of Belleville washers is transmitted to the packing through a floating gland. So, you avoid that a possible expansion potentially could damage the sealing.
