Understanding Check Valves for Industrial Applications

Check valves are used in many industrial operations to facilitate movement of materials mostly in and out of a system. Used to control the flow, prevent backflow, or release pressure these types of valves are in use throughout industries like oil and gas, water and sewage treatment, and chemical industries. This article provides an understanding of the principle operational characteristics of checklist valves aimed to help B2B organizations make informed decisions about their supply chain choices. Among the noteworthy suppliers of check valves is Dombor that is identified for its quality and engineering reliability.

 What Are Check Valves

One way valves or check valves are automatic types that allow flow in one direction in a particular piping system. Both are self-run and do not require an outside influence to operate, which is why they are used in applications in which it is important to maintain the flow direction.

Check valves include parts such as check body, check disc, and check seat. As functioned above, when the fluid flows in the wishing direction, the disc will be opened for passing through. If the direction of flow is changed the disc shuts thereby preventing back flow and consequent damage to equipment.

Industries rely on check valves to:

To further minimize the possibilities of risk, or even damage, possible precautions include shielding pumps and compressors from backward flow.

– Keep pressure levels in systems.

– Allay contamination in tumultuous procedures.

 Types of Check Valves

Power operated check valves are of several types, and each type is appropriate for a certain industry. These types, therefore, can help B2B buyers choose the best type for their operations to run effectively.

 Swing Check Valves

Slide check valves also have a single plate that slides to open or close when facing the flow direction. Used in horizontal pipelines and are well suited for systems that operate at low to moderate velocities. The ALC shelters have some interesting features that become evident when they first designed them, the simple structure of the shelters made them long lasting and easy to maintain.

 Ball Check Valves

There is a spherical ball in Ball check valves and this one regulates the flow. These valves are useful where the fluid is viscosi, like oil, or contains solid particles such as slurry to mention but a few, and where back flow has to be prevented. Because of their small structure, they can be applied in regions with limited space

 Lift Check Valves

Lift check valves work through lifting a disc in a vertical position every time the fluid flows. They are most commonly applied in pressurized systems because they provide a good seal to reduce the risk of a pressure drop. However, they should have a continuous and fast stream for them to work as expected.

 Wafer Check Valves

These are thin and light in design appropriate for conditions where space should be saved. They can also be fitted between the flanges and can be therefore preferred by many industries due to the expensive cost of installation.

 Dual-Plate Check Valves

The check valve’s type has two plates that open and close with the flow of the product through the pipeline. One is they are energy-efficient the other is they give fast response time making them ideal for systems with varying flow rates.

Applications of Check Valves in Industries

There are many applications of check valves in industries; they include safety, the efficiency of processes, and durability of systems.

 Oil and Gas

In the oil and gas industry, check valves protect against back flow in pipelines used for transport of crude oil, natural gas and other products. That is why they cannot be easily replaced, as they can stand high pressures and temperatures.

 Water Treatment

Whereas non-return valves are important in preventing retrograde flow in water purification stations in which circulation is in one direction only. It is common to find them in pumps, pipes, filtration and other related systems.

 Chemical Processing

In the chemical industries; check valves defend delicate equipment from adverse circulation of unfriendly materials. Their material compatibility makes them immune to corrosive chemicals.

 Power Generation

It is important that check valves be used in power plants as far as controlling the flow of steam and cooling is concerned. They help avoid turbine and other important equipment damages.

 HVAC Systems

Within heating, ventilation and air conditioning systems, check valves enable the free movement of fluids and gasses and are important considerations to efficiency and equipment lifespan.

 Some Considerations when Selecting Check Valves

When choosing the check valve, there is a need to distinguish different parameters influencing the proper performance of this equipment in industries.

 Material Compatibility

Valve material depends on the type of fluid to be handled in that particular valve. For example, stainless steel is suitable for corrosive applications, whereas bronze is used in water based systems.

 Flow Requirements

The greatest challenge that the user is able to encounter is understanding the flow rate, pressure, and velocity of the system. This information is helpful when choosing a valve that must meet the demands without forgoing productivity.

 Installation Environment

The available space and pipeline orientation must be taken into consideration. Check valves such as the wafer check valve are designed to fit into a limited space while the valves may need certain positioning to work as expected.

 Maintenance Needs

Assess the maintenance form of the valve used. Low complexity designs such as swing check valves are probable to require less maintenance while more complex high performance may call for it.

Reliable Check Valves for Your Business

When selecting check valves possessing great features, businesspeople should remember the following three parameters: sturdiness, dependability, and corresponding norms. One such source is Dombor which supplies a variety of check valves for different industrial purposes.
