Pressure Sensing Pipe: The DP 143 valve controls the downstream pressure by sensing the down stream pressure through an external sensing pipe taken from down stream to the pilot valve chamber (10) Fitting of this external pressure sensing pipe is described in the User manual If the external sensing pipe is not provided then the valve controls by internal pressure sensing pipe (19). However the capacity in this case will be reduced.
Installation: See User manual supplied with the valve.
