These unique regulators decrease pressurization time and lower maintenance costs. Applications • Hydraulic Power Units (HPU) • Wellhead control panels Features and Benefits • Unique integrated bypass valve simplifies the high pressure system design which results in fewer components and leak paths for added safety • The addition of the 50-4000 Series to HPU units simplifies complex start up procedures while decreasing down time associated with filling long umbilicals • Controls large variations in flow rates at pressures up to 20,000 psig / 1379 bar • New stem and seal design extends regulator service life in crucial high pressure water-based hydraulic applications Visit our website at emerson.com or contact us at (800) 447-1250
