Valve Series

Series 170
Angle & Choke Valves

The Series 170 Control Valve product range emulates the Series 110 design except that the valve body is an angle type constitution instead of a globe style.

This range of control valves can be fitted with the same trim design options as the Series 110 product. It is used where the pipework configuration necessitates an angle pattern design.

The Series 170 can also be adapted to the choke valve application and again fitted with a selection of trim designs to suit each application in conjunction with the angle body configuration.

This range can be fitted with standard and severe service trim designs.

In conjunction with this the trims could be supplied manufactured in hard metal for potentially erosive applications.
