Higher numbers indicate            a smoother finish. RMS:Defined as Root Mean Square roughness,             this method measures a sample for peaks             and valleys. Lower numbers indicate a             smoother finish. Ra: Known as the Arithmetic Mean, this measure           ment represents the average value of all peaks           and valleys. Lower numbers indicate a smooth           finish.     Electric Actuator 120VAC 12/24 VDC NEMA 4/7 Positioners 4-20 MA Reversing Telemetry Battery back-up Pneumatic Actuators Double Acting Spring return Solenoids Valves Limit Switches Positioners 3-15 PSI Positioners 4-20 mA Intelligent Positioner Declutchable manual Override  Manual valves Oval handle Spring-Return Stem Extensions Fusible Link Locking Device Gear Operators Wing Handle
