Smart PRV

Product Brand: Farris

The Farris’ Smart PRV features a 2600 Series Pressure Relief Valve (PRV) Equipped with a Fisher 4320 Wireless Position Monitor. The 4320 features a magnetic array that detects changes in the PRV’s stem position. The wireless device’s sample changes in the stem position every x second. The sample reports are fed into the local wireless network, where they can be tracked in plant asset management systems.

smart prv: technology & performance

Farris Smart PRV technology is a simple, powerful solution to improve your ability to monitor critical safety valves and their effects on plant performance. Overpressure events are unpredictable, can go unnoticed, and consequently can be challenging to estimate. Using the Smart PRV system ensures facilities can record overpressure events. 

 

SmartPRV provides:

  • Equipped plants with the ability to track and monitor valves in real-time
  • Provides immediate feedback during an overpressure event
  • Feedback includes the time and duration of the overpressure event
  • Allowing plants to more accurately estimate releases

PRV 2600 Series: Operation

 

The Smart PRV features a 2600 series bellows valve. The 2600 series features an all stainless steel stem; this construction cost-effectively eliminates dangerous sticking due to galvanic corrosion at the upper guiding point in the spring adjusting screw. 

The Farris design incorporates a positive connection of parts between the valve stem and the stem retainer, and between the disc and disc holder. This allows complete freedom of action for alignment purposes while retaining the positive connection of the threads.  

Smart PRV provides feedback on every PRV discharge event, including the time and duration, allowing plants to estimate releases more accurately. 

PRV Applications

The Smart PRV is designed to function equally well for use in: 

  • Air 
  • Gas 
  • Vapor 
  • Steam or Liquid service 

FAQ

What is a PRV? 

PRVs are pressure regulating valves that are designed to maintain a system at or below a safe pressure. When the pressure in the system starts to exceed the safe point, the valves relieve the system to siphon off excess material that could potentially cause issues or damage to the system, components or operators.   

What is a Smart PRV? 

In partnership with Emerson, Farris Engineering offers Farris SmartPRV technology, a 2600 Series pressure relief valve PRV equipped with a Fisher® 4320 wireless position monitor. 

Wireless monitoring of PRVs provides equipped plants with the ability to track and monitor valves in real-time, providing immediate feedback during an overpressure event. 

What are the benefits of wireless monitoring? 

Until Smart PRV, monitoring PRVs and the amount of product being released has been a daunting task due to traditional equipment and technologies’ limitations. 

This left plants with the inability to estimate product losses without using overly conservative assumptions. Emission fines based on unquantified releases are typically assessed based on the worst-case scenario. Plants are forced to pay the highest possible fine along with the additional administrative and documentation costs incurred during the emissions reporting process. 

Farris Smart PRV technology offers a simple, powerful solution to improve the ability to monitor critical safety valves and their effects on plant performance. 

What is a PRV system? 

A PRV system consists of a relief valve or pressure relief valve (PRV) that controls or limits the pressure in a system. If it wasn’t in use, the pressure could build up and create an issue that could cause damage to the application, component system or operators nearby.  

What is the function of a PRV? 

The purpose of a pressure relief valve is to control or limit surges of pressure within pipelines, acting as protection for the system, and defending against instrument or equipment failure. 

What are the two types of PRV? 

There are two types of PRV pressure reducing valves available, direct acting and pilot operated. 

Direct-acting pressure reducing valve: 

Direct-acting pressure reducing valves are ideal for small loads and designed for point of use installation. So, they are manufactured in a compact size, cheap, and very easy to install. They are the simplest type of pressure-reducing valve that operates with either a flat diaphragm or convoluted bellows.  

Pilot Operated pressure reducing valve: 

Pilot-operated pressure reducing valves are used for larger loads requiring close pressure control. This means they are larger in size and costly. They also provide a faster response to load variation and are suitable for a wider range of flow rates.
