Actuation Method
   Actuation Method:       
   Your choices are...         
   Manual       A handwheel or lever is utilized to drive a series of gears (typically worm gears) whose ratio results in a higher output torque compared to input (manual) torque. 
   Electric       A single or three phase AC motor or DC motor is utilized to drive a combination of gears to generate the desired torque level. 
   Pneumatic       Air pressure is used to supply pressure, which is converted to linear or rotary motion. 
   Hydraulic       Fluid pressure is used to supply pressure, which is converted to linear or rotary motion. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Valve Motion:       
   Your choices are...         
   Rotary Motion Valve       Rotary motion valves (rotary valves) such as ball, plug and butterfly valves that rotate through a quarter-turn (90 degrees) or more from open to close.  This includes multiturn valves. 
   Linear Motion Valve       Linear motion valves (linear valves) such as gate, globe, diaphragm, pinch, and angle-style valves have a sliding stem design that pushes the closure element open or closed. The valve stem may rise while rotating (multi-turn) or may rise without rotating. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Operation       
   Your choices are...         
   On / Off (isolating)       Actuator motion is limited to preset or open and closed positions. 
   Modulating       Actuator motion is controlable to allow valve to be "throttled" to keep process in proper measure or proportion. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

General Specifications
   Control Signal Input:      Throttling valves regulate the flow, pressure or temperature of the service. They can move to any position within the stroke of the valve and hold that position, including full on or full off. The addition of an actuator to a throttling valve, which has the ability to adjust to a signal, is called a control valve. An actuator used in throttling or modulating service is part of the control loop consisting of a sensing device, controller and an actuator mounted on a valve. The actuator receives a control input signal from the controller or positioner and adjusts closure element position accordingly.
   Your choices are...         
   Milliampere Control Signal       The input control signal to the actuator is a milliampere signal. 
   Voltage Control Signal       The input control signal to the actuator is a voltage signal. 
   Pressure Control Signal       The input control signal to the actuator is a pressure signal. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   DC Voltage:         
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

   Your choices are...         
   Single Phase         
   Three Phase         
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Air Supply Pressure       The input pressure necessary to achieve desired torque or thrust output. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Hydraulic Fluid Supply Pressure       The input pressure necessary to achieve desired torque or thrust output.

   Your choices are...         
   Close at No Power       In case of power failure, actuator closes the valve. 
   Close at No Control       In case of loss of control signal, actuator closes the valve. 
   Open at No Power       In case of power failure, actuator opens the valve. 
   Open at No Control       In case of loss of control signal, actuator opens the valve.
