Single-stage High Flow Pressure Reducing Regulator
The DR70 series is a single stage high flow pressure reducing regulator, available in either NPT or BSP thread with ½”, ¾” or 1” sizes.
DR70 is suitable for pipeline applications where high flow of water, chemicals, liquids or gases are being used.
The drop-preventing design ensures stable and precise regulation of outlet (P2) pressure even with a wide pressure variance at the inlet (P1).
DR70 series can be used with an inlet pressure of 420 bar (6000psi) or 100 bar (1450psi).
Full scale outlet pressures available are:
- 10 bar (145psi)
- 25 bar (362psi)
- 50 bar (725psi)
- 70 bar (1000psi)
- 150 bar (2100psi)
- 250 bar (3600psi)
- 350 bar (5000psi)
DR70 can be controlled either via a knob or a bolt.
Body materials are available in either brass or 316L stainless steel with either Teflon or Vespel valve seat materials.
