THESE INSTRUCTIONS PROVIDE THE CUSTOMER/OPERATOR WITH IMPORTANT PROJECT-SPECIFIC REFERENCE INFORMATION IN ADDITION TO THE CUSTOMER/ OPERATOR’S NORMAL OPERATION AND MAINTENANCE PROCEDURES. SINCE OPERATION AND MAINTENANCE PHILOSOPHIES VARY, BAKER HUGHES (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.
Model Number Explanation The FEP-CH pilot is available in two different models to cover The Becker FEP-CH series single-acting pilot represents a sensing pressures from 550 psig to 1500 psig. The number breakthrough in valve control technology for the natural gas expressed in the FEP model designation is the maximum industry.
In all, when ordering, the customer should follow this format: Ordering Example: BPE Model FEP-1000-CH-NC (30-0039), Pressure Control Range 550-1000 psig (Yellow Spring , 25-1306), 1/8” Nozzle (25-1030), “M” Orifice Assembly (25-8162) Table 3.
Setpoint Motors are equipped with internal limit switches to prevent over-travel of setpoint. 4-20 mA feedback of Remote Setpoint Module is standard. All Becker RSM Series remote Setpoint Modules are rated Explosion Proof Class1, Div 1 for use in hazardous locations. Standard RSM input signals are:...

2398 lbf/in. From Table 9, the for a standard orifice set on #3 in the forward flow direction A FEP-1000-CH gas application using a standard orifice set on is 0.026. Finally, the effective diaphragm area of the FEP #3 in the forward flow direction configuration.
Table 10 shows the results of the droop calculation (equation closed. Using the model FEP-1000-CH in a gas application with 7) for ΔP values of 200, 400, 600, 800, and 1000 psig. For a ΔP = 800 psig as an example, we can see from Table 10 that if convenience, Table 11 shows the same results as Table 10 given the output is suddenly closed the pressure will increase 10.9 psig...

Body Diaphragm Assembly Step 2. Slide a piston spacer (I) over each piston. The grooved side of the piston spacer should be facing away from the Step 1. Slide a diaphragm (L) over each piston taking into pistons as shown in Body Spacer Assembly Figure here below. account the diaphragm convolute orientation shown in Body Step 3.

Step 1. Press fit the thrust bearing (AA) into the bearing case by spinning the assembly. Make sure that the spring touches no (BB for a FEP-1000-CH and CC for a FEP-1500-CH). parts of the adjusting screw when spinning. If the spring does touch any part of the screw, then replace the spring and repeat the test.
