Specifications: Models: L2 (Single-Acting, for Inlet Control), L2sj (Double-Acting, for Outlet Control) Type: Pilot-Operated Float Level Controller Operation: Mechanical / Pneumatic (Self-Contained) Process Connections & Mounting: Cage Size: Standard displacer cage lengths from 14 in to 120 in (355 mm to 3048 mm). Process Connection: Typically 2-inch or 3-inch NPT or flanged cage connections. Mounting: Internal cage, external cage, or bridle mounting. Pilot & Supply Pressure: Supply Pressure Range: 35 to 150 psig (2.4 to 10.3 bar) Pilot Output Pressure: Varies based on supply pressure and float position, used to actuate the main control valve. Materials of Construction: Cage/Body: Cast Iron (standard), Ductile Iron, Carbon Steel, Stainless Steel. Float: Stainless Steel. Internal Parts: Stainless Steel and Brass. Performance & Sizing: Control Sensitivity: Highly dependent on float size, lever arm length, and supply pressure. Capacity: The controllers themselves do not have a flow capacity (Cv). They are sized based on their ability to pilot and control a separate main control valve, which is selected based on the required flow rate.
