Valve Actuators

Linear stroke electric actuators and rotary stroke electric actuators are suitable for use on our valves.

Linear Stroke Electric Actuators

Linear stroke electric actuators such as our CE approved MF-63000 series mount directly on the valve body. No linkage is required for valves of 2 inch or smaller size. These are floating control units that stay in position when power is removed. The MF-63123 can be converted to full proportional control with the addition of a plug-in analog input board.

Rotary Stroke Box Style Actuators

Rotary stroke actuators such as our cUL approved EA series box style units are the most common form used for valves. The rotary action is converted to a linear stroke by the linkage kit. Only actuators with a 180° stroke can be used. These actuators must be coupled to a stem-up open valve body. Attempting to use these with stem-up closed valve bodies will result in physical damage.

The actuators in the selection table below can be used on valve assemblies. For details on the actuator specifications, consult the actuator section of this catalog. All actuators may be ordered as components and assembled to the valve body component using the appropriate linkage kit component. However, actuators with a three-digit Actuator code below may also be ordered as complete valve assemblies. These actuators are identified as part of an available factory assembly by using the (1) three digit Actuator code in place of the “000” and (2) the Control Form code for an assembled valve in place of the “VB” (valve body only) code in the complete valve assembly model code.

Valve Actuators

Selection of Actuator

In the table the Control Form defines the kind of control action the actuator will execute. Other than “VB”, this Control Form will only ever appear in the valve model code in the case of complete factory valve assemblies.

 

In the table the Control Form defines the kind of control action the actuator will execute. Other than “VB”, this Control Form will only ever appear in the valve model code in the case of complete factory valve assemblies.

 

The table also provides important specifications to help select the correct actuator for an application. These specifications include actuator torque (in-lb) or force (lb) and travel time in seconds. Actuators may use different linkage kits, depending on the valve body to which the actuator is coupled. The available linkage kits for a particular combination of valve body and actuator is defined in the Valve Assembly Tables.

Valve Close-Off Pressure Tables

Every valve assembly has a finite ability to close-off against inlet pressure, the pressure of the controlled fluid at the inlet of the valve body. The following tables list the maximum pressure at which each valve body actuator combination is rated. Note that these values are not the recommended operating pressures. High differential pressure across the valve body may result in excessive cavitation of the valve seat, even though it does not exceed the close-off pressure rating listed here. Please refer to the section on cavitation limitations in the valve sizing section.

 

This table lists the rated maximum close-off pressure in psig for valves with rotary box style actuators that have 50 to 60 in-lbs of torque. Note: The differential pressure across the valve when closed off is, in nearly all cases, equal to the absolute inlet pressure. The following actuators are in this group: (EA12, EA42, EA42-A, EA44, EA44-A, EA52, EA54, EA54-A)
