Description

Description: Position Indication: The Actuatorvalve position is shown via a color-coded insert and NAMUR slot. The indicator is suitable for either direction of actuator rotation, and drive shaft size. Actuator Drive: The NAMUR drive slot on the position indicator permits direct drive engagement of switch boxes and positioners. Direct Mounting of Sensors: The indicator can be supplied with metal inserts to allow for easy installation of many types of sensors. Operating Media: Dry or lubricated air or inert n-corrosive gases on condition that they are compatible with wetted internal actuator parts and lubricant. The operating media dew point must equal either **0℃(**0°F) or *0℃ below the ambient temperature. The maximum particle size must not exceed *0 microns. Supply Pressure: For Double Acting and Spring Return actuators the maximum supply pressure is 8 bar(**6 psi). The minimum supply pressure is 2.5bar(*0psi). Operating Temperature : Normal temperature (NT) actuator with NBR“O-rings” from **0℃(*4°F) to **0℃(***6°F). Low temperature (LT) actuator with Silicon “O-rings” from **0℃(**8°F) to **0℃(***6°F). High temperature(HT) actuator with FPM “O-rings” from **5℃(*5°F) to ***0℃(***0°F). CAUTION: For high and low temperature service special grease is required. High and low temperature will vary the output torque of the actuator. Please contact a ROPO sales representative for each application. Stroke: See technical data Standard construction: *0°rotation with stroke adjustment at 0°and *0°+/- 4°. Operating Time: See Technical Data Sheet. Lubrication: The ROPO Rack and Pinion Actuator comes factory lubricated for the life under normal operating conditions. The standard lubricant is suitable for use from **0℃(*8°F) **0℃(***6°F). For high and low temperature service where special grease is required please contact a ROPO sales representative. Construction: Durable twin piston rack and pinion actuator design is suitable for both indoor and outdoor applications.
