|90-180 Degree Valve Types -- Morpac Actuator Division
This type of actuator is characterized by the ball or butterfly types of valves, where total movement of the valve is accomplished in a rotation of 90 degrees. These actuators are fairly universal in their application on these types of valves, and can be readily changed from one valve to another, with minimal or no changes required in position limit switch settings. These actuators are factory set up at a true 90 degree position. Only minor adjustments in the field would be required for errors in couplings, keyways or shaft variations. Each actuator has provision for independent setting of Open and Close torque.
10003 depicts a common Butterfly Valve application. This shows a 5" Military "High Performance" type valve, manufactured to meet Specification Mil-V-24624. The yoke adapter shown permits adjustment of the valve stem packing, with removing the actuator from the valve. The actuator base has a window to view the mechanical position of the valve stem, and includes adjustable mechanical stops. These stops limit overtravel of the valve when manually operated by the handwheel. Total travel is 90 degrees. Version for use with a remote controller shown.
