  • Page 8: Principles Of Operation

    Principles of Operation GE’s Becker VRP-B-CH pilot and double-acting cylinder actuator can be used in conjunction with varying valve types to provide a complete package for stable, accurate pressure control over a wide range of applications. The energy for control valve operation comes from the pressure differential between the pilot supply and discharge pressures.
