How to Select the Right Valve Positioner for Rotary and Linear Valves

Valve positioners are useful gadgets that play a crucial role in the regulation of liquid and gaseous flow in various types of valves. The selection of the right valve positioner is necessary for the particular type of valve be it a rotary valve or a linear valve. Knowing the types of valve positioners available, what to look for when selecting a valve positioner and how to properly install and calibrate them is one way to help maintain peak performance and efficiency in your valve system.

Types of Valve Positioner: Explained In Simple Language:

Different types of valve positioners are available for each application. When rotary valves are used, you can select pneumatic, electro-pneumatic, or digital positioners. Pneumatic positioners act through air pressure and drive a valve stem; electro-pneumatic positioners add an electrical signal to the air pressure for better accuracy. Digital positioners, however, rely on sophisticated digital technology for precise positioning.

Considerations When Selecting a Valve Positioner:

There are a number of things to consider when choosing a valve positioner for your application. To begin, find out the size and type of valve you have (not just make and model) as this will: affect what type of positioner is appropriate. Other environmental oil and gas drilling companies considerations such as temperature, pressure, and the presence of potential hazards should also be considered to guarantee that the positioner will be able to operate in these environments.

Also, think about how much accuracy and control your system will need from the valve. More accurate oil drilling positioning is possible, but would require a digital positioner of more sophistication. Budget and maintenance are other points to take into account when you select a valve positioner.

Selecting the Best Valve Positioner for Your Application:

Once you have determined the type of valve considering the above mentioned factors you can correlate the most suitable valve positioner for your application. This will assist you in selecting the appropriate positioner suitable to meet your particular system requirements and configuration. Make sure the positioner is suitable for the valve and that it can offer the required control and performance to obtain an optimal operation.

Installation and Setup Guidelines for Valve Positioners:

It is very important that the valve positioner be installed and calibrated correctly to operate at peak performance. Make sure to follow the crude oil drilling manufacturer instructions when fitting the positioner to guarantee that it is properly and firmly mounted to the valve. Positioner calibration is also important so the valve is actually being controlled as the positioner states.
