HOW TO SELECT THE RIGHT CONTROL VALVES

The Valve Industry is a highly complex application-oriented one where the navigating of the feasible technology options are just the starting point. Even the valves specification has become a complex job to do. Augmenting the specification by a proper approach to emissions compliance, digitalization along with other regulatory standards is a constantly evolving criteria. Fevisa, one of the leading valve manufacturers and valve suppliers, are experts in proper control valve selection guidance. Now let us discuss how the control valve selection needs to be done as guided by our experts.

The Control Valve: The control valves play an important role in establishing and maintaining an efficient process. When selecting control valves, it’s advisable to be sure to evaluate how the valve’s features match the application’s requirements in terms of connectivity for remote monitoring, stable flow control, versatility and ability to handle a range of flows.

Working: Control valves especially the stock valves regulate the flow of fluid by compressing or expanding the fluid passageway. This particular function alters the volume and the pressure of the of fluids that passes through the system within a given time frame. A rising stem control valve design, is the one where valve stem raises and lowers the valve trim package to increase or decrease the size of the passage, resulting in steady, increased or decreased flow.

Features to look for:

During the selection process, look for and evaluate how the options under consideration meet these key features:

1. Versatility — Will the valve handle the full breadth of conditions between the minimum and maximum specified conditions? How robust is it to withstand out of bound conditions? Will it offer a longer service life without any maintenance?
2. Works equally well on all conditions — A proper Standardization across the base installation helps in the maintenance requirements as well as the spare parts inventory.
3. Stable flow control — Having Consistent control in all conditions is critical since inconsistency will lead to production downtime causing loss of product.
4. Has necessary control characteristics — Varied process conditions require varied control characteristics. Hence the characteristics required must be known and evaluated to confirm that the control valve meets them.
5. Connectivity —Ensure the valve is compatible with the process management system since remote monitoring/control is highly critical to processing applications.
6. Range — Ensure that the valve can handle all flow changes in the process.

Maintenance:

In addition to valve selection, it is important that the valves have ensured proper maintenance features as follows:

• Proper access for inspection/adjustment
• Shaft having protection from blowout
• Seat ring for tight shutoff that is self-aligning
• Coupled /Splined shaft connections that allows easy actuation connection/disconnection
• Easy access to work on the valve without removing the body from the system
• The valve’s ability to maintain tight shutoff to minimize loss of working fluid

For a critical fluid system applications, the control valves that you can trust are designed by our experts at Fevisa, a leading Valve stockist in UAE. We are a premier manufacturer of valves especially control valves.

We ensure that our valves have an:

• Precise flow and pressure control for stable & consistent production results.
• Reduced operating costs.
• Efficient energy usage.
• Lower maintenance coupled with repair costs for a longer valve trim life.
• Increased availability.

Always remember that control valves are not isolation valves, hence don’t use them in the place of isolation valves for plant safety.

Fevisa, one of the leading control valve suppliers, we have the superior functional capability with international standards like WRAS approved Valves and UL FM approved Valves.   Fevisa is a renowned Valve Stockist as their valves are all prevalent product in industries there meeting their needs.

Our Valves Made in Europe so our valves are popularly called as European Valve Manufacturers. We are supplying ball valves, gate valves, butterfly valves and more. Contact our team of professionals for a better valve selection
