1 EP-1000/100-CH Series lexflo Pilot EP-1000/100-CH lexflo Pilot Provides Superior Performance for High Pressure Setpoint pplications Up To 100 psig (896 ) EP-CH Series lexflo Pilot The EP-1000-CH and EP-100-CH Series Pilots are a reversible pressure control pilots (seat & nozzle) that are used in conjunction with lexflo Regulators to provide pressure control. The EP-1000/ 100-CH is typically utilized for high pressure setpoint applications up to 100 psig (896 ). The EP-CH features superior lockup and droop capabilities over other manufacturer's flexible element pilots. pplications include pressure reduction, monitor regulators, backpressure control, and relief valve. The EP-1000/100-CH features a friction-free design, sensitive sensing diaphragm, high sensitivity and minimal droop. dditionally, note that the EP-1000/100-CH Series lexflo Pilot is a submersible design that is ideally-suited for vault applications that fill with water.

The EP-1000-CH and lexflo Regulator provide the ideal combination for high pressure setpoint regulation. The Model EP-1000-CH provides setpoints up to 1000 psig (6895 ). The Model EP-100-CH provides setpoints up to 100 psig (896 ). The EP-1000-CH and EP-100-CH may be utilized for pressure reduction, relief service and backpressure control. ll Becker EP Pilots are field reversible to allow for use in all application configurations. LOW igure.0 - EP-1000-CH lexflo Pilot for Downstream Pressure Control The EP-1000-CH is shown combined with a Model 900TE lexflo Regulator for downstream pressure control. The EP-1000-CH and Model 900TE are ideal for applications that require superior accuracy. The EP-1000-CH provides unparalleled accuracy, minimal droop, and excellent lock-off characteristics. The EP-1000-CH allows flexible element regulators such as the Model 900TE lexflo to close off flow with minimal overshoot of pressure. This is of particular importance in dead-end system that are equipped with relief valves.

3 How It Works: EP-1000/100-CH configuration shown is for Pressure Reduction (Downstream Pressure Control) in conjunction with a Becker Model 900TE lexflo Regulator. Increasing downstream pressure will cause the EP-1000/100-CH to close the lexflo Regulator and restrict flow. Initially, the downstream pressure is above the setpoint of the EP-1000/100-CH. With the lexflo jacket pressure equal to the upstream pressure, the lexflo Regulator remains fully closed (ig. 7.1). s downstream pressure falls to a pressure equal to setpoint of the EP-1000/100-CH pilot, the lexflo Regulator jacket pressure will begin to decrease. When the lexflo jacket loading pressure falls below the upstream pressure, the lexflo Regulator will begin to open and flow gas (ig. 7.). If the downstream pressure falls to a point nearly equal to the upstream pressure, the lexflo Regulator will fully unload the jacket pressure. With the jacket pressure equal to the downstream pressure, the lexflo Regulator is fully open (ig. 7.). The upstream pressure will be slightly higher than the downstream pressure do the inherent "cracking pressure" associated with the rubber element (tube) of the lexflo Regulator. djustable Orifice ssembly P J EP-1000-CH lexflo Pilot P P 1 P O LOW Legend Inlet Pressure (Upstream Pressure) P 1 Outlet Pressure P O Jacket Pressure P j Sensing Pressure (Downstream Pressure) P igure 7.1 lexflo Regulator ully Closed When the downstream pressure is above the setpoint of the EP-CH, the lexflo jacket pressure will be equal to the upstream pressure.
