MANUAL GEAR ACTUATORS

Transcription

1 MANUAL GEAR ACTUATORS Type M Series and MA manual gear actuators are recommended for use on JAMESBURY ball and butterfly valves. For the sake of convenience, and where lever-handles present space problems, gear actuators are the ideal choice. Type M Series and MA actuators are fully enclosed weather-proof, all-cast-iron, and carbonsteel construction.they are factory lubricated for their lifetime, requiring no future lubrication, and each unit includes a pointer to indicate valve position. Standard M units are temperature rated from -40 F to +176 F (-40 C to +80 C). Standard MA units are temperature rated from -40 F to 212 F (-40 C to 100 C). Units with lower or higher temperature ratings are available on application (See How To Order section). Type M Series and MA gear actuators are available factory-mounted on valves or separately for field installation. Item Components Material Material Description Specification 1.

MA MA MA MA ACTUATOR SELECTION To select the proper actuator for a particular valve and service, first determine the maximum operating torque that will be required for the valve from the valve torque chart in the appropriate valve bulletin, taking into consideration valve size, seat material, maximum pressure differential, and service. Then refer to the tables on page 4 and select the actuator that will provide a torque output no less than the required operating torque for the valve. Note: Full MA manual gear actuator designations carry two additional numbers after the above identifying designations, i.e. MA These two numbers indicate the output drive square or socket dimensions and will normally be determined by Metso or its distributors. Drive dimensions are shown in the How to Order section on page 5. TECHNICAL BULLETIN 9/09 3
