DP 23 is a SG Iron pilot operated pressure reducing valve suitable for steam or compressed air.
15,20,25,40 & 50 NB Screwed : BSPT / NPT for 15,20,25NB Flanged : BS10 table “F/H” for 40& 50NB
PMO - Maximum allowable Pressure : 17 TMO - : Note : The Kv values are full capacities and should be used for safety valve sizing purpose only For conversion Cv (UK)=Kv x 0.963 Cv (US)=Kv x 1.156 SIZE DN15 DN20 DN25 DN40 DN50 KV 2.8 5.5 8.1 17 28 bar g Maximum allowable Temperature 232 C. Cold hydraulic test pressure : 34 bar g Spring range : 0.3 to 17 bar g
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
