REFERENCE INFORMATION IN ADDITION TO THE CUSTOMER/OPERATOR’S NORMAL OPERATION AND MAINTENANCE PROCEDURES. SINCE OPERATION AND MAINTENANCE PHILOSOPHIES VARY, GE (GENERAL ELECTRIC COMPANY AND ITS SUBSIDIARIES AND AFFILIATES) DOES NOT ATTEMPT TO DICTATE SPECIFIC PROCEDURES, BUT TO PROVIDE BASIC LIMITATIONS AND REQUIREMENTS CREATED BY THE TYPE OF EQUIPMENT PROVIDED.
The GE’s Becker VRP-B-CH series balanced seat design, double- VRP-B-CH pilot may be used for pressure control applications with acting pilot represents a breakthrough in valve control technology setpoints ranging from 3 psig to 1500 psig.
1903 kPa 6550 kPa 6550 kPa These models should only be used for applications that require high gain. Consult GE prior to selecting these models. Remote Setpoint Change Options • The SM-1000 series motors accept a 24 VDC or 120 VAC input.
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.
VRP-B-CH is in service. Turn the sensitivity adjustment drum to the right (decreasing No other adjustments need to be made. GE recommends numbers) until the exhaust port just starts bleeding gas. noting the setpoint change per revolution of the control spring Check the total deadband again and repeat this process until installed in the pilot.
