Technical Specifications Category Specification Model R622-BCF Type Rotary Control Valve (Eccentric Plug) Body Style Flanged, Angle Pattern (Standard for R/ET series) End Connections Flanged, ANSI Class 300 RF (Interpreted from "62-2") Valve Size Likely 2-inch (DN50). The exact size is defined by the "62" code. Trim Characterization Eccentric Rotary Plug with approximately equal percentage flow characteristic. Trim Material Standard Stainless Steel (e.g., 316 SS). The absence of an "H" suggests it is not a hardened trim. Leakage Class With metal seats, typically ANSI Class IV (0.01% of rated capacity). Actuator Type Pneumatic Spring-Diaphragm Actuator (defined by "BCF" suffix). Actuator Action Determined by "BCF" code. Could be direct-acting (air-to-open) or reverse-acting (air-to-close). This must be confirmed from the datasheet. Air Signal Standard 3-15 psig (0.2-1.0 bar). Spring Range Defined by the "BCF" code (e.g., 3-15 psig, 6-30 psig, etc.). Temperature Range Standard from -20°F to +450°F (-29°C to +232°C). Extended ranges possible with special seals.
