Type ZB – The ZB is the standard valve for sizes 1” – 10”. Its optimum designed aerodynamic flow path through the valve results in very low pressure losses. It is also available with API 6D face-to-face dimensions (ZD).

Type ZS – With a shorter face-to-face (wafer type) than the ZB and where pressure loss across the valve is not such a significant consideration, the ZS is installed where space and weight is at a premium. This type is only available on special request.

The Z range is suitable for all kinds of liquid and gaseous fluids and all installation positions.
