Electric Ball Valve Actuators for Plastic Valves

September 6, 2013 – 11:13

EBV Series EBVA Electric Actuators for 2-Way and 3-Way Ball Valves
w/ Direct Manual Override,Visual Position Indicator,CE/IP 65 type Housing Back to Summary

Features:

  • Multi-Voltage with automatic voltage sensing
  • Rugged plastic construction for corrosive atmospheres.
  • Direct manual override with visual position indication helps prevent disaster in the event of a power failure.
  • LED status lights.
  • Electronic over-torque protection.
  • Thermally protected motor.
  • Anti-condensation heater.
  • CE Marked IP-65 water and dust proof enclosure.
  • Easily attached to MBV Ball Valves with Double-D drive.
  • Simple connections for remote operation and position indication.
  • Fail-Safe and 4-20 mA digital positioner options for control valve applications with characterized profile ball designs.
  • Now available in 3" and 4" sizes.

Series EBVA Actuators have many clear and important advantages over competitor's products:

  • Manual override is direct to valve -- not through a gear train -- to eliminate potentially hazardous conditions.Do not consider a valve actuator without manual override unless you have a convenient and regularly tested shutoff capability as backup.
  • Many "discount" actuators are not thermally protected.They could potentially run and run until overheating leads to failure or even fire.
  • Series EBVA position indicator is mechanically attached to the valve shaft and the running lights are wired to the motor.Indicator lights on most low cost actuators are electrically wired to your supplied signal.If the valve is jammed,if the motor burns out,if the gear box strips -- the light will not indicate the position of the valve -- it simply indicates your electrical signal.
Any one of these shortcomings could result in disaster under the right circumstances.We urge you to research actuator specifications carefully,and make an informed,safe decision.

Please consult factory before specifying.

Completing the Actuator Model Number

The base actuator number above is only the first part of the specification process. The base actuator for all size valves is offered as either a standard actuator or with a combination of options,and must be specified with a suffix number.In other words,an "EBVA1" must be completed with a second number,for example,EBVA1-1.A table of these suffix numbers is below.

Partial sterling combustion engine design

2008-08-28 18:29:38 by wuzawuzzal


The main idea is to have the cylinders charge and detonate fuel in an computer controlled automated way as to reduce the amount of combustion cycles that would other wise be necessary to keep the engine running.
The piston is directly connected to a pneumatic actuator that extends and retracts to either draw in fresh fuel or expel exhaust gases. A charge is loaded and valves are operated pneumatically to open a path to the drive train or to exhaust spent fuel. A pressure relief valve is installed to prevent over pressure and also to direct excess cylinder pressure to a pressure tank (not shown) to be used to power actuators
