Masoneilan 8012 and 8013 Series Advantages

Precise, Straightforward, Durable 

The main purpose of a valve positioner is to guarantee that the position of the control valve plug consistently corresponds to the controller output signal, irrespective of factors such as packing box friction, diaphragm actuator hysteresis, or any unbalanced forces acting on the valve plug. The controller output signal can be either pneumatic or electric, depending on the specific type of positioner used. The Baker Hughes Masoneilan 8012 and 8013 Series cam positioners are force-balance electro-pneumatic devices that achieve remarkable dynamic response and positioning precision by directly comparing the valve position with a controlled DC output signal. A single multi-lobe cam allows for field-adjustable linear or percentage-control characteristics without the need for additional components.

The 8013 Series electro-pneumatic cam positioner possesses the following capabilities: 

• It can modify the valve operation (an increase in the electrical signal results in the opening or closing of the valve) 
• It can alter control characteristics (either linear or equal-percentage) 
• It can manage two control valves in a split-range configuration  This positioner is offered in two action types: direct action, where an increase in the electrical signal leads to an increase in output pressure, and reverse action, where an increase in the electrical signal results in a decrease in output pressure. Furthermore, the positioner facilitates precise split-ranging of the controller output signal, enabling the sequential operation of two control valves using a single controller.
