How a Pressure Pilot Works | Kimray Product Overview

A control valve is a vital piece of equipment for controlling oil and gas operations. But today we’re going to talk about a small component that may be even more important: a pressure pilot.

Below we'll cover what a pressure pilot does and take a brief look at four common types of pressure pilots.

What is a Pressure Pilot?

A pressure pilot is used to monitor and control pressure upstream or downstream of a control valve. It does this by pneumatically positioning the valve to achieve your desired set point.

A pressure pilot is almost always used on a high pressure control valve package. Valve packages like these allow producers to effectively control their oil and gas separation equipment.

 

Advantages of Kimray Pilots 

Here are a few of the reasons energy producers rely on Kimray pressure pilots:  

  1. Durability. The first is the durability that is synonymous with the Kimray name.  

    The pressure pilot was one of Kimray’s first innovations, and there’s a reason that energy producers have trusted it for decades. We use only the highest quality materials, and our products are manufactured at our headquarters in Oklahoma City, USA.  
     
  2. bellows pilot options with different spring options and direct vs indirectModular Design. Another reason producers like to use our pilots is because of their modular design. 

    We provide packages for pressure regulation that can be customized to your needs, whether you are holding back pressure on separation equipment or reducing pressure for your compressor

    Components in the pilot can also be changed out to adapt to various operating pressures or different modes of action, like 
    indirect or direct.  
     
  3. Versatility. Finally, we provide material options like steel components and various types of elastomers to help keep your operation running regardless of your production conditions.


4 Types of Pneumatic Pressure Pilots

These four popular pneumatic pilots monitor the upstream or downstream pressure of a control valve and can be used in both back pressure and pressure reducing applications.

  1. Diaphragm Controlled Low Pressure Pilot

  2. Diaphragm Controlled High Pressure Pilot

  3. Bellows-Controlled High Pressure Pilot

Part of its value is that it can act in either direct or indirect mode and can be converted to operate at a vast span of different pressures—from 75 to 2500 PSI.  
     
  4. Pressure Differential Controller

This controller has inputs for both upstream and downstream pressure. Those two pressures work against each other with a spring in the pilot, which controls the difference between the pressures.

Note that all our pneumatic pilots can be operated emission-free, when you use nitrogen or compressed air as the supply source.

Electric Pilot

If you are ready to incorporate automation into your operation, you can also check out our Electric Pilot.  

The Electric Pilot can be used with any electric actuator to automate a control valve. The pilot takes an input signal—like a pressure or timer—and outputs a signal to an electric actuator.  

It offers a ton of versatility, and can be used in back pressure, pressure reduction, pressure differential, gap control, suction control, or as a timer.  

 

Certifications 

Manufactured and assembled in the USA, Kimray Pressure Pilots are certified for use in North and South America and most areas around the world.  

We have 25 distribution centers in the U.S. and international distribution partners globally. Kimray is also an ISO 9001-certified manufacturer.
