The DP23 controls the pressure by sensing the downstream pressure through a pressure sensing pipe taken to the union (item L) or through the internal sensing pipe (item M). Fitting of the external pressure sensing pipe is described in the User Manual supplied with the valve. Capacity is reduced and there is a possibility of hunting if an external pressure sensing pipe is not fitted.
The valve should be installed in a horizontal pipeline with direction of flow as indicated by the arrow on the valve body. Full instructions are supplied in the User Manual
